Water Level and Flow Control Bench Manufacturer

Teaching objectives

  • 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).

Technical specifications
