WATER LEVEL CONTROL BENCH MP115

Floor mounted bench. The water level control loop is composed of a differential pressure measurement (dP) located under a transparent column, a centrifugal pump with loop on a tank through and a proportional pneumatic valve controlled by a PID controller. A valve under the column allow to introduce a disturbance.

MP115

Teaching objectives

- Study of a level control loop (1st range)
- Study of the static answer
- Identification in open loop and closed-loop mode
- Calibration of a level sensor
- Disturbance of the set point.

 

Technical specifications
