Abstract
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.
