Water Level and Flow Control Bench

Teaching Objectives of Water Level and Flow Control Bench

The equipment allow, for example to experiment the following subjects :
Study of a static answer (level or flow).
Study of flow measurement with diaphragm and differential pressure transducer with digital display with square root extractor.
Study of (Broïda or other) Identifications on the level or the flow process control.
Study of simple level process control (with V1 or V2).
Study of simple flow process control
Study of a process control by extent sharing.
Study of a process level control with cascade on the flow.
Study of a Split-Range process control.
The model is designed so that the disturbances are easily reproducible. That’s allows a fine study of the influence of the control parameters (needle valve with 10 revolutions).
