Flow control bench, level, and cascade level / flow

It will be possible, for example, to achieve :

• A study with a static response (level or flow).
• Simple level or flow regulation
• A 1st order or 2nd order regulation on the level
• A level control cascade on the flow.
• A delay effect

The bench consists of :

• Two vats
• A feed tank, filling up with mains water by means of a hose
• Auxiliary delay circuit with coil
• A pallet flow meter
• A float flowmeter for comparison of flow measurements on the supply
• A float flowmeter for calibrated flow disturbance
• A pneumatic valve.
• An IP converter
• Regulator regulator
• Two mbar pressure sensors for level measurement, located under the two altuglas tanks
• Two manual valves needle, adjustment and easy identification of the number of revolutions.
• Stainless steel centrifugal pump
• A master regulator
• A slave regulator
• Measurement and setpoint display for both controllers.
• The painted steel control cabinet features:
• The lockable disconnector,
• The power indicator,
• Re-arming,
• The emergency stop,
•  The 2 regulators,
• A 4-position switch for the choice of: first-order level control; 2nd-order level regulation; flow regulation; cascade control.
• Double-well secured terminals allow you to recover the 0-10V of the inputs and outputs of the regulators.
• Control and protection of the pump.

Compound acquisition module:
- an RS485 / RS232 converter
- a Windows operating system that allows:
. Reading the PID parameters,
. The plot of the curves,
. The configuration of the remote controller
. Archiving values.
