Function

  • Operation and Control:
    • Protects pumps by switching electrical circuits when liquid flow decreases or stops.
    • Enables sequential control of pump operation.
    • Allows automatic starting of auxiliary pumps and machines.
    • Activates alarm and signalling systems in case of insufficient or interrupted flow.
    • Disconnects water flow cooling processes and associated equipment when flow is interrupted.
    • Switches off sprayers when air supply fails in heating coil systems.
    • Disconnects machine tools when freezing oil flow is interrupted.
