Abstract (en)
A system for measuring the flow rate of fluids discharged from positive-displacement pumps, and real-time monitoring of these pumps. The system comprises pressure and proximity sensors and a microcomputer. The pressure sensors transmit the pressure in the discharge chambers of the pumps to the microcomputer in the form of signals. The proximity sensors provide a reference in the operating cycle of the pumps. The computer monitors sensor status and processes the data received from the sensors to provide monitoring of the pump. It transmits the results via a serial communications bus. In the event of a malfunction, an alarm is transmitted.
