You are here: Home / Process Engineering / Industrial Engineering / Process Control / 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.


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

- A tank in PVC
- A column in altuglas, height 1300 mm
- A stainless steel centrifugal pump
- A controller :
- universal entry: mV, V, my, T/L
- dual display measure/instruction
- Algorithm control : P, PI, PID, T autoadaptatif.
- A converter P/I
- A differential pressure sensor, 0-100 mbar,
- A set of manual valves
- Filter regulator
- A flow meter
- A control cabinet
- Floor mounted bench with stainless steel frame and aluminium nuts
- Shunt for the measure of the output power of the regulator and the signal of the pneumatic valve with the help of secured plugs for connecting recorder or other devices.

- Data acquisition module ref MAC composed with :
- A regulator with a RS485 communication card. In this case the reference number of the equipment equipped with the regulator with card become MP115VE
- A converter RS485/RS232
- A data acquisition software under Windows allowing :

- Reading PID parameters,

- The drawing of the curves,

- The remote control of the regulator parameters

- The storage of the values

- PC computer type Pentium IV
