This bench allows to study different technologies of level measurement sensors used in the industry.


Teaching objectives

- Study of the sensors installation

- Study of the different cases of applications.

- Calibration of the sensors.

- Determination of the characteristic curves of the sensors and their accuracy.



The water network feed a vat through an adjustable pressure regulator (0 to 3 bar). The vat is equipped with a flow adjusting valve, an overflow, a total draining valve, a discharge valve with a leak flow adjusting valve and a steel rule to locate easely the level.

In the vat are installed several types of level measurement sensors: an ultrasonic sensor, a capacitive effect sensor, a float sensor and a hydrostatic pressure sensor.

The display of the different sensors is common and situated in the front side of the electrical cabinet. A 4 positions switch allows to select the sensor to study.

The device is mounted on a welded stainless steel frame, with PVC panel and is equipped with 4 adjustable feet.
