System Having Drum Discharge Outlet Sensors and Method of Characterizing Fresh Concrete Delivery Using Same
4 Feb 21
There is described a system generally having a rotatable drum rotatably for receiving fresh concrete, the drum having inwardly protruding blades mounted inside the drum which, when the drum is rotated in an unloading direction, force fresh concrete inside the drum towards a discharge outlet of the drum, at least one discharge outlet sensor disposed at the discharge outlet of the drum and being configured to sense the presence of fresh concrete at the discharge outlet as the drum rotates in the unloading direction; and a controller communicatively coupled with the at least one discharge outlet sensor, the controller being configured for performing the steps of: receiving a signal from the at least one discharge outlet sensor indicative of the presence of the discharged fresh concrete at the discharge outlet as the drum rotates in the unloading direction; and determining at least one parameter based on the received signal.

Utility
Methods and System for Measuring Density of Fresh Concrete
22 Jul 20
The method for determining density of fresh concrete inside a drum of a mixer truck involves a probe mounted inside the drum, extending in a radial orientation of the drum and being moved circumferentially as the drum rotates.

Methods and System for Handling Fresh Concrete
11 Mar 20
The method of handling fresh concrete generally includes the steps of receiving a viscosity value of the fresh concrete and a pressure value of a pressure exerted on a Theological probe moving in the fresh concrete; using a processor, accessing at least two calibration data sets, the at least two calibration data sets including combinations of different reference pressure values and associated reference workability values for a corresponding one of at least two reference viscosity values; determining a viscosity difference value by comparing the received viscosity value to the at least two reference viscosity values; and determining a workability value of the workability of the fresh concrete based on the reference workability values associated with reference pressure values corresponding to the received pressure value in the at least two calibration data sets and on the viscosity difference value; and handling the fresh concrete based on the determined workability value.

Probe and method for obtaining rheological property value
30 Dec 19
The probe can include a base and a resistance member extending from the base and onto which a resistance pressure is imparted by a rheological substance when the resistance member is submerged and moved therein.

Utility
System and method for determining a status of a valve using an actuator accelerometer and a reference accelerometer
9 Dec 19
The system for determining a status of a valve being mounted in a liquid supply line of a concrete mixer and being actuatable via an actuator generally has: an actuator accelerometer mounted to the actuator and being adapted to measure an actuator position associated with a position of the valve; a reference accelerometer mounted to the concrete mixer and being adapted to measure a reference position fixed relative to the concrete mixer, the actuator position and the reference position being measured while the concrete mixer is fixed relative to the ground; a computing device adapted to receive the actuator and reference positions, the computing device being adapted to determine the status of the valve based on the actuator position, the reference position and calibration position data; and to generate status of the valve indicative of the determined status of the valve.
