ABSTRACT:
A system for monitoring the transport of concrete includes a computer, pump sensors, and a positive displacement pump for pumping concrete through a pipeline. The monitoring system senses and records the number of pump strokes and the pumping pressure during each pump stroke. The actual volume and instantaneous pumping rates of concrete pumped during each pump stroke are calculated. Based upon a calculated velocity and upon the pressure of the concrete being pumped, the monitoring system provides predicted component wear information for maintenance scheduling and warranty verification.
