ENGINEERING MEASUREMENTS COMPANY REPORTS

FISCAL 2001 SECOND-QUARTER RESULTS

LONGMONT, COLORADO - DECEMBER 15, 2000 - ENGINEERING MEASUREMENTS COMPANY
(NASDAQ NM: EMCO) today reported results for the three months ended October 31,
2000. The Company's current fiscal year ends on April 30, 2001.

For the three months ended October 31, 2000 the Company reported net income of
$50,000, or $0.01 per diluted share, on net sales of $3.0 million, compared to
net income of $11,000 on net sales of $2.5 million in the second quarter of
fiscal 2000. For the six months ended October 31, 2000 the Company reported a
net loss of $73,000, or $0.02 per diluted share, on sales of $5.5 million,
compared to net income of $16,000 on sales of $4.7 million in the comparable
period a year ago.

At the end of the second quarter of fiscal 2001, Company had $4.0 million in
working capital, no long-term debt, and stockholders' equity of $7.0 million.

As announced on July 6, 2000, the Company signed a merger agreement with
Advanced Energy Industries, Inc. Under the terms of the agreement, EMCO
securities holders would have received 900,000 shares of Advanced Energy stock
in exchange for all of the securities of EMCO.

Due to a decline in Advanced Energy's stock price, the parties amended and
restated the merger agreement as of October 20, 2000 to change the consideration
payable by Advanced Energy to the EMCO shareholders from stock to cash. Under
the amended and restated agreement, Advanced Energy will pay EMCO shareholders
an aggregate of $30 million plus an amount equal to the cash exercise prices
paid by EMCO option holders on any exercise of EMCO options between October 20,
2000 and the completion of the merger. The amended merger agreement will be
voted on at a special meeting of shareholders scheduled to take place on January
2, 2001. The agreement, which does not require the approval of Advanced Energy's
shareholders, is subject to the approval of two-thirds of EMCO's shareholders
and certain other conditions detailed in a proxy statement dated December 1,
2000.

Engineering Measurements Company designs, manufactures, and markets electronic
and electro-mechanical precision instruments for measuring and controlling the
flow of liquids, steam, and gases, and also engages in contract electronic
printed circuit board assembly.
