A system for a concrete mixer having a drum receiving fresh concrete therein. The system generally has: a sensor measuring a set of measurand values indicative of a measurand associated with at least one of the fresh concrete, the drum and components of the concrete mixer; and a controller communicatively coupled to the sensor, the controller performing the steps of: accessing the set of measurand values generated by the sensor; using a trained data processing engine stored on the non-transitory memory, at least one of determining a property value indicative of a property of the fresh concrete, determining a parameter value indicative of a parameter of the drum, and determining that the set of measurand values are indicative of some operating conditions of the concrete mixer; and outputting a signal based on said determining.

System and method for monitoring fresh concrete being handled in a concrete mixer using trained data processing engines

A method for determining cleanliness of a drum of a fresh concrete mixer truck. The method generally has: rotating the drum about the rotation axis with a constant torque; using a rotational speed sensor, measuring a plurality of speed values corresponding to speeds at which the drum rotates at different moments in time during said rotating; and using a controller, receiving the plurality of speed values; accessing calibration data having different reference speed values-related data associated to corresponding reference degrees of cleanliness of the drum; comparing at least some of the speed values to the calibration data; and determining a degree of cleanliness of the drum based on said comparison.

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. Rheological properties can be obtained using values indicative of the resistance pressure both in a low speed range and in a high speed range.
