SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

          Certain statements contained in this Form 10-Q, as well as other
information provided from time to time by the Company or its employees, may
contain forward looking statements that involve risks and uncertainties that
could cause actual results to differ materially from those in the forward
looking statements. The words "anticipate," "believe," "estimate," "expect,"
"think," "should" and "objective" or similar expressions are intended to
identify forward looking statements. All such forward looking statements are
based on the Company's then current views and assumptions and involve risks and
uncertainties that include, among other things:

     -    the continued shift in the Company's business from lower cost, local
          read meters toward more expensive, value-added automatic meter reading
          (AMR) systems;

     -    the success or failure of newer Company products, including the
          Orion(R) radio frequency mobile AMR system, the absolute digital
          encoder (ADE(TM)) and the Galaxy(R) fixed network AMR system;

     -    changes in competitive pricing and bids in both the domestic and
          foreign marketplaces, and particularly in continued intense price
          competition on government bid contracts for lower cost, local read
          meters;

     -    the actions (or lack thereof) of the Company's competitors;

     -    changes in the Company's relationships with its alliance partners,
          primarily its alliance partners that provide AMR connectivity
          solutions, and particularly those that sell products that do or may
          compete with the Company's products;

     -    changes in the general health of the United States and foreign
          economies, including housing starts in the United States and overall
          industrial activity;

     -    increases in the cost and/or availability of needed raw materials and
          parts, including recent increases in the cost of brass housings as a
          result of increases in the commodity prices for copper and zinc at the
          supplier level and resin as a result of increases in petroleum and
          natural gas prices;

     -    the ability to improve operating results for foreign markets that have
          experienced historical losses;

     -    changes in foreign economic conditions, particularly currency
          fluctuations between the United States dollar and the euro; and

     -    changes in laws and regulations, particularly laws dealing with the
          use of lead (which can be used in the manufacture of certain meters
          incorporating brass housings) and Federal Communications Commission
          rules affecting the use and/or licensing of radio frequencies
          necessary for AMR products.

          All of these factors are beyond the Company's control to varying
degrees. Shareholders, potential investors and other readers are urged to
consider these factors carefully in evaluating the forward looking statements
and are cautioned not to place undue reliance on such forward looking
statements. The forward looking statements made in this document are made only
as of the date of this document and the Company assumes no obligation, and
disclaims any obligation, to update any such forward looking statements to
reflect subsequent events or circumstances.

                               BADGER METER, INC.

         NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1.   In the opinion of management, the accompanying unaudited consolidated
     condensed financial statements of Badger Meter, Inc. (the "Company")
     contain all adjustments (consisting only of normal recurring accruals)
     necessary to present fairly the Company's consolidated condensed financial
     position at March 31, 2006, results of operations for the three-month
     periods ended March 31, 2006 and 2005, and cash flows for the three-month
     periods ended March 31, 2006 and 2005. The results of operations for any
     interim period are not necessarily indicative of the results to be expected
     for the full year.

     The preparation of financial statements in conformity with U.S. generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the amounts reported in the financial statements
     and accompanying notes. Actual results could differ from those estimates.

     Certain reclassifications have been made to the 2005 consolidated condensed
     financial statements to conform to the 2006 presentation.

2.   The consolidated condensed balance sheet at December 31, 2005 was derived
     from amounts included in the Company's Annual Report on Form 10-K for the
     year ended December 31, 2005. Refer to the footnotes to the financial
     statements included in that report for a description of the Company's
     accounting policies and for additional details of the Company's financial
     condition. The details in those notes have not changed except as discussed
     below and as a result of normal adjustments in the interim.

     GOODWILL Goodwill increased from $6.6 million at December 31, 2005 to $6.7
     million at March 31, 2006 as a result of translation adjustments for
     goodwill denominated in foreign currencies.

     WARRANTY AND AFTER-SALE COSTS The Company estimates and records provisions
     for warranties and other after-sale costs in the period the sale is
     reported. After-sale costs represent a variety of activities outside of the
     written warranty policy, such as investigation of unanticipated problems
     after the customer has installed the product, or analysis of water quality
     issues. Changes in the Company's warranty and after-sale costs reserve for
     the three-month periods ended March 31, 2006 and 2005 are as follows:

     STOCK-BASED COMPENSATION PLANS At March 31, 2006, the Company has two types
     of stock-based employee compensation plans, which are described more fully
     in Note 1 "Summary of Significant Accounting Policies" under the heading
     "Stock-Based Compensation Plans" and Note 5 "Stock Option Plans" in the
     Notes to Consolidated Financial Statements in Part II, Item 8 of the
     Company's 2005 Annual Report on Form 10-K.

     The Company recognizes the cost of share-based awards for the two types of
     stock-based employee compensation plans on a straight-line basis over the
     vesting period of the awards. Total stock compensation expense recognized
     by the Company for the three month periods ended March 31, 2006 and 2005
     was $218,000 and $32,000, respectively.

     Stock Options:

     The Company has six stock option plans which provide for the issuance of
     options to key employees and directors of the Company. Each plan authorizes
     the issuance of options to purchase up to an aggregate of 400,000 shares of
     Common Stock, with vesting periods of up to ten years and maximum option
     terms of ten years. As of March 31, 2006, options to purchase 287,268
     shares remain available for grant under four of these plans.


                                        7



     Prior to January 1, 2006, the Company accounted for stock compensation
     plans under the recognition and measurement provisions of Accounting
     Principles Board Opinion No. 25 (APB 25), "Accounting for Stock Issued to
     Employees," and related Interpretations, as permitted by Financial
     Accounting Standards Board (FASB) Statement No. 123 (SFAS 123), "Accounting
     for Stock-Based Compensation." No stock-based employee compensation cost
     was recognized for stock option awards in the Consolidated Statements of
     Operations for the periods prior to January 1, 2006 as all options granted
     under those plans had an exercise price equal to the market value of the
     underlying Common Stock on the date of grant.

     Effective January 1, 2006, the Company adopted the fair value recognition
     provisions of FASB Statement No. 123(R) (SFAS 123(R)), "Share-Based
     Payment," using the modified-prospective-transition method. Under this
     transition method, compensation cost recognized in the first quarter of
     2006 includes compensation costs for all share-based payments granted prior
     to, but not yet vested as of January 1, 2006, based on the grant date fair
     value estimated in accordance with the original provisions of SFAS 123 and
     compensation cost for all share-based payments granted subsequent to
     January 1, 2006, based on the grant date fair value estimated in accordance
     with the provisions of SFAS 123(R). There were no stock option grants made
     in the first quarter of 2006. The Company estimated the fair value of its
     option awards granted prior to January 1, 2006 using the Black-Scholes
     option-pricing formula, and will continue to use this model. Results for
     prior periods have not been restated.

     As a result of adopting SFAS 123(R) on January 1, 2006, the Company's
     earnings before income taxes and net earnings for the three month period
     ended March 31, 2006 were $107,000 and $78,000 lower, respectively, than if
     the Company had continued to account for share-based compensation under APB
     25.

     Prior to the adoption of SFAS 123(R), the Company presented all tax
     benefits of deductions resulting from the exercise of stock options as
     operating cash flows in the Consolidated Condensed Statements of Cash
     Flows. SFAS 123(R) requires the cash flows resulting from the tax benefits
     of the tax deductions in excess of the compensation cost recognized for
     those options (excess tax benefits) to be classified as financing cash
     flows.

     The following table illustrates the effects on net earnings and earnings
     per share if the Company had applied the fair value recognition provisions
     of SFAS 123 to stock option plans during the three months ended March 31,
     2005. These pro forma calculations only include the effects of stock-based
     compensation granted since January 1, 1995. The value of the options is
     amortized to expense on a straight-line basis over their vesting periods
     and forfeitures are recognized as they occur.

     Nonvested Stock:

     Director Stock Grant Plan: Non-employee directors receive an annual award
     of 600 shares of Common Stock under the shareholder-approved 2002 Director
     Stock Grant Plan. The Company records compensation expense for this plan
     ratably over the annual service period beginning May 1. Director stock
     compensation expense recognized by the Company for the three-month periods
     ended March 31, 2006 and 2005 was $64,000 and $32,000, respectively. As of
     March 31, 2006, the unrecognized compensation cost related to the nonvested
     director stock award that is expected to be recognized over the remaining
     one month is estimated to be approximately $20,000.

     Restricted Stock: On April 28, 2005, a restricted stock plan was approved
     which provides for the issuance of nonvested Common Stock to certain
     eligible employees. The plan authorizes the issuance of up to an aggregate
     of 50,000 shares of Common Stock, of which a net of 15,500 were issued in
     the second quarter of 2005. This restricted stock award has a three-year
     cliff vesting period contingent on employment. There were no restricted
     stock grants made in the first quarter of 2006. Restricted stock
     compensation expense recognized by the Company for the three-month period
     ended March 31, 2006 was $47,000.

     The fair value of nonvested shares is determined based on the market price
     of the Company's shares on the grant date. As of January 1, 2006, 15,500
     restricted shares were issued with a fair value of $36.65 per share, and
     there were no changes to these amounts during the period ended March 31,
     2006. As of March 31, 2006, there was $394,000 of unrecognized compensation
     cost related to nonvested restricted stock that is expected to be
     recognized over a weighted average period of 2.08 years.

3.   The Company maintains a non-contributory defined benefit pension plan for
     its domestic employees and a non-contributory postretirement plan that
     provides medical benefits for certain domestic retirees and eligible

     The Company previously disclosed in its financial statements for the year
     ended December 31, 2005 that it did not expect to contribute funds to its
     pension plan in 2006. While the Company believes that it will not be
     required to make a contribution in 2006, such belief is based upon the
     estimated return on assets as of the annual measurement date of September
     30, 2006.

     The Company also disclosed in its financial statements for the year ended
     December 31, 2005 that it estimated it would pay $1.0 million in other
     postretirement benefits in 2006. As of March 31, 2006, $250,000 of such
     benefits were paid. The Company continues to believe that its estimated
     payments for the full year are reasonable. Note that the amount of benefits
     paid in calendar year 2006 will not impact the expense for postretirement
     benefits for the current year.

4.   The Company guarantees the debt of the Badger Meter Officers' Voting Trust
     ("BMOVT"), from which the BMOVT obtained loans from a bank on behalf of the
     officers of the Company in order to purchase shares of the Company's Common
     Stock. The officers' loan amounts are collateralized by the Company's
     shares that were purchased with the loans' proceeds. There have been no
     loans made to officers by the BMOVT since July 2002. The Company has
     guaranteed $0.8 million and $1.1 million of the BMOVT's debt at March 31,
     2006 and December 31, 2005, respectively. The current loan matures in April
     2006, at which time it is expected to be renewed. The fair market value of
     this guarantee at March 31, 2006 continues to be insignificant because the
     collateral value of the shares exceeds the loan amount. It is the Company's
     intention to eliminate the BMOVT by December 31, 2010, because it no longer
     fulfills its original purpose of providing officers with loans to purchase
     Common Stock. The Company has no other off-balance sheet arrangements.

     The Company guarantees the outstanding debt of the Badger Meter Employee
     Savings and Stock Ownership Plan that is recorded in long-term debt, offset
     by a similar amount of unearned compensation that has been recorded as a
     reduction of shareholders' equity. The loan amount is collateralized by
     shares of the Company's Common Stock. A payment of $120,000 in the first
     quarter of 2006 reduced the loan from $0.9 million at December 31, 2005 to
     $0.8 million at March 31, 2006.

5.   Total comprehensive income was $4.4 million and $2.8 million for the
     three-month periods ended March 31, 2006 and 2005, respectively. Included
     in the three-month periods ended March 31, 2006 and 2005 was a $0.2 million
     gain and a $0.8 million loss, respectively, of other comprehensive income
     related to foreign currency translation adjustments.


                                       10



6.   In the normal course of business, the Company is named in legal proceedings
     from time to time. There are currently no material legal proceedings
     pending with respect to the Company. The more significant legal proceedings
     are as follows.

     The Company is subject to contingencies relative to environmental laws and
     regulations. Currently, the Company is in the process of resolving matters
     relative to two landfill sites. Provision has been made for all known
     settlement costs, which are not material.

     The Company is also a defendant in numerous multi-party asbestos lawsuits
     pending in various states. These lawsuits assert claims alleging that
     certain industrial products were manufactured by the defendants and were
     the cause of injury and harm. The Company is vigorously defending itself
     against these claims. Although it is not possible to predict the ultimate
     outcome of these matters, the Company does not believe the ultimate
     resolution of these issues will have a material adverse effect on the
     Company's financial position or results of operations, either from a cash
     flow perspective or on the financial statements as a whole.

     The Company has evaluated its worldwide operations to determine whether any
     risks and uncertainties exist that could severely impact its operations in
     the near term. The Company does not believe that there are any significant
     risks. However, the Company relies on single suppliers for certain castings
     and components in several of its product lines. Although alternate sources
     of supply exist for these items, loss of certain suppliers could
     temporarily disrupt operations in the short term. The Company attempts to
     mitigate these risks by working closely with key suppliers, purchasing
     minimal amounts from alternative suppliers and by purchasing business
     interruption insurance where appropriate.

     The Company reevaluates its exposures on a periodic basis and makes
     adjustments to reserves as appropriate.

ITEM 2 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

BUSINESS DESCRIPTION AND OVERVIEW

     The Company is a leading marketer and manufacturer of products using flow
measurement and control technologies developed both internally and with other
technology companies. Its products are used to measure and control the flow of
liquids in a variety of applications. The Company's product lines fall into two
general categories, utility and industrial. The utility category is comprised of
two product lines, residential and commercial water meters (with various
automatic meter reading (AMR) technology systems), which are generally sold to
water utilities and constitute a majority of the Company's sales. Industrial
product line sales comprise the remainder of the Company's sales and include
automotive fluid meters and systems, small precision valves, electromagnetic
meters, impeller flow meters and industrial process meters (all with related
accessories and instrumentation).

     Residential and commercial water meters and related systems are classified
as local (or manual) read meters or AMR products. Local read meters consist of a
water meter and a register. With AMR meters, the register digitally encodes the
mechanical reading and its radio frequency transmitter communicates the data to
a computerized system that collects the data and sends it to specific utility
computerized programs. Net sales and the corresponding net earnings depend on
unit volume and mix of products, with the Company generally earning higher
margins on residential AMR products (the impact of AMR on commercial products is
not as significant given the higher sales prices of commercial meters). The
Company sells AMR products of other companies as well as its own proprietary
product, Orion(R), which has higher margins than the other AMR products.
Orion(R) is currently being sold as a walk-by/drive-by system, but also has the
ability to connect with a variety of other technologies, such as power line
carrier, broadband over power line, municipal WI-FI and radio frequency systems
to allow for remote reading of the data. Net sales and the corresponding net
earnings are therefore also dependent on the mix of AMR products between
proprietary and non-proprietary products.

     There is a base level of annual business for utility products driven by
replacement units and, to a lesser extent, housing starts. Sales above the base
level depend on conversions to AMR away from manual read meters. The Company
believes that conversion from local read meters to AMR products can accelerate
replacements of meters and result in growth, because it is estimated that only
15-20% of the water meter market has been converted to AMR. Badger Meter's
strategy is to solve customers' metering needs with its proprietary meter
reading systems or other systems available through alliances within the
marketplace.

     The industrial products generally serve niche markets and have in the past
utilized technology derived from utility products to serve industrial uses. As
these markets evolve, these products are becoming more specialized to meet
industrial flow measurement and communication protocol requirements. Serving
these markets allows the Company to expand its technologies into other areas of
flow measurement and control, as well as utilize existing capacity and spread
fixed costs over a larger sales base.

BUSINESS TRENDS

     As noted above, the Company sells AMR products of other companies as well
as its own proprietary product, Orion(R). The Company currently has a
distribution agreement under which it resells products produced by Itron, Inc.
Prior to the Company's introduction of its own proprietary Orion(R) products,
Itron water utility related products were a significant contributor to the
Company's results. The Company's Orion(R) products directly compete with Itron
water AMR products and, in recent years, many of the Company's customers have
selected Orion(R) products. As a result, the Company's 2005 sales of Itron
products decreased approximately 12%, while Orion(R) sales doubled compared to
2004. In the first quarter of 2006, this trend continued as sales of Itron
products decreased approximately 6%, while Orion(R) sales increased 43% as
compared to the first quarter of 2005. The Company expects this trend to
continue in the future as it moves towards the February 2009 expiration of the
distribution agreement with Itron, and as Itron introduces new products not
offered under the agreement. Decreases in sales of Itron products have been
offset by increases in sales of Orion(R) products that produce a higher gross
margin than the Itron products. As a result, the Company does not expect this
trend to have a material negative impact on the Company's financial position or
results of operations.


                                       12


RESULTS OF OPERATIONS - THREE MONTHS ENDED MARCH 31, 2006

     Net sales for the three-month period ended March 31, 2006 increased $6.6
million, or 12.1%, over the same period in 2005. The overall sales increase was
driven by increased sales in both local read and AMR meters as well as
significant increases in commercial meters, all caused by volume increases,
mitigated somewhat by slightly lower industrial sales.

     Residential and commercial water meter sales represented 77.4% of total
sales in the first quarter of 2006 compared to 73.2% in the first quarter of
2005. These sales increased $7.5 million to $47.3 million compared to $39.8
million in the same period in 2005. These increases were in local (or manual)
read water meter units, units utilizing AMR technologies, which carry higher
prices and contributed to the majority of the increase in net sales for the
quarter, and commercial meters. Most notable in the increase of AMR technologies
was the increase in sales of the Company's proprietary AMR product, Orion(R),
which increased approximately 43% over the amount sold in the first quarter of
2005. This was mitigated somewhat by sales decreases in other AMR technologies.

     Industrial sales are affected by economic conditions, domestically and
internationally, in each of the markets served by the various product lines. In
total, industrial products represented 22.6% of total sales for the three months
ended March 31, 2006 compared to 26.8% for the same period in 2005. Industrial
sales decreased $0.9 million to $13.7 million in the first quarter of 2006
compared to $14.6 million in the first quarter of 2005. This was driven
primarily by lower sales of automotive fluid meters and related systems sold
through the Company's French subsidiary.

     Gross margins in total for the first quarter of 2006 were 34.6% compared to
35.6% in the first quarter of 2005. The decrease was the net impact of lower
margins on automotive fluid meters and related systems due to competition,
offset somewhat by higher residential meter margins due to the higher mix of AMR
products, particularly the Orion(R) product which carries higher margins.

     Selling, engineering and administration costs for the first quarter of 2006
were 22.0% as a percent of net sales compared to 23.6% for the same period in
2005. The decrease in selling, engineering and administration costs as a percent
of net sales is the result of cost containment efforts and higher sales levels,
offset by normal inflationary pressures. In addition, the first quarter of 2006
includes $107,000 of additional compensation expense due to expensing stock
options for the first time to comply with Financial Accounting Standards Board
Statement No. 123(R) (SFAS 123(R)), "Share-Based Payment".

     Interest expense for the first quarter of 2006 was less than $0.1 million
lower than the same period in the prior year primarily due to lower debt
balances, offset somewhat by higher interest rates.

     The effective tax rate for the first quarter of 2006 was 42.0% compared to
41.0% in the same period in the prior year. Both periods are negatively affected
by the impact of the valuation reserve for the operating losses of the Company's
French subsidiary. The French operation continues to generate losses and the
Company is exploring options for the future of this business.

     As a result of the above-mentioned items, net earnings for the first
quarter of 2006 were $4.2 million compared to net earnings in the first quarter
of 2005 of $3.6 million. On a diluted earnings per share basis, this equated to
$0.59 per share for the first quarter of 2006 compared to $0.51 for the same
period in 2005.

LIQUIDITY AND CAPITAL RESOURCES

     The main sources of liquidity for the Company typically are cash provided
by operations and borrowing capacity. For the first three months of 2006, $2.7
million of cash was provided by operations, primarily as the net result of
increased earnings adjusted for depreciation and amortization, offset by
increased inventory and receivables.

     The change in the receivables balance from $30.5 million at December 31,
2005 to $34.9 million at March 31, 2006 was primarily due to increased sales and
the timing of certain customer payments.


                                       13



     Inventories at March 31, 2006 have increased $0.9 million to $32.9 million
from the December 31, 2005 balance of $32.0 million due primarily to increased
sales and the longer lead times for residential products.

     Property, plant and equipment increased $0.4 million since December 31,
2005. This is the net result of $2.0 million of capital expenditures and $1.8
million of depreciation expense adjusted for the effects of foreign exchange
rates on the foreign assets.

     Short-term debt and the current portion of long-term debt at March 31, 2006
decreased $0.6 million to a combined $15.7 million versus a balance at the end
of 2005 of $16.3 million. Long-term debt increased to $15.7 million at March 31,
2006 from $15.4 million at December 31, 2005. In 2005, the Company obtained a
$10 million five-year term loan to replace short-term debt. This increase in
long-term debt was reduced by normal scheduled payments. Overall, the Company's
total debt position has decreased as cash was provided from operations. At March
31, 2006, none of the Company's debt carries financial covenants or was
collateralized.

     Payables increased to $15.0 million at March 31, 2006 from $11.5 million at
December 31, 2005 primarily as a result of the timing of payments. Accrued
compensation and employee benefits declined $1.8 million since December 31, 2005
to $4.6 million due to the first quarter 2006 payments of amounts accrued at
December 31, 2005, offset somewhat by costs accrued for 2006 expenses to date.
Income and other taxes payable increased to $3.0 million at March 31, 2006 from
$1.8 million at December 31, 2005 as a result of the timing of tax payments.

     Common stock and capital in excess of par value have increased from
December 31, 2005 due to new shares issued in connection with the exercise of
stock options. Employee benefit stock decreased as a result of a payment made on
the ESSOP loan during the first quarter of 2006, amortization of nonvested stock
expense and the adoption of FAS 123(R), which required the reclassification of
amounts from employee benefit stock to capital in excess of par value.

     Badger Meter's financial condition remains strong. The Company believes
that its operating cash flows, available borrowing capacity, including $34.4
million of unused credit lines, and its ability to raise additional capital
provide adequate resources to fund ongoing operating requirements, future
capital requirements and the development of new products.

OTHER MATTERS

     There are currently no material legal proceedings pending with respect to
the Company. The more significant legal proceedings are as follows.

     The Company is subject to contingencies relative to environmental laws and
regulations. Currently, the Company is in the process of resolving matters
relative to two landfill sites. Provision has been made for all known settlement
costs, which are not material.

     The Company is also a defendant in numerous multi-party asbestos lawsuits
pending in various states. These lawsuits assert claims alleging that certain
industrial products were manufactured by the defendants and were the cause of
injury and harm. The Company is vigorously defending itself against these
claims. Although it is not possible to predict the ultimate outcome of these
matters, the Company does not believe the ultimate resolution of these issues
will have a material adverse effect on the Company's financial position or
results of operations, either from a cash flow perspective or on the financial
statements as a whole.

     No other risks or uncertainties were identified that could have a material
impact on operations and no long-lived assets have become permanently impaired
in value.

ACCOUNTING CHANGE

     The Company began expensing the cost of stock options on January 1, 2006
when it adopted Financial Accounting Standards Board Statement No.123(R),
"Share-Based Payment". See Note 2 to the Notes to Unaudited Consolidated
Condensed Financial Statements in this Form 10-Q for information regarding this
accounting change.
