WATER FLOW CONTROL BENCH MP116

Floor mounted bench composed of a flow measurement by a diaphragm with differential pressure sensor, a centrifugal pump with loop on a tank through a proportional pneumatic valve controlled by a PID controller. A by-pass circuit allow to introduce a disturbance of the flow that the controller offset by modifying the opening of the pneumatic valve to maintain the flow at the set point in the circuit.

MP116

Teaching objectives

- Study of a pressure process control
