The general purpose level controller is offered in two configurations for pump and valve control. The LC10 accepts one level sensor input and provides one 16A relay for high level control or low level control. The LC11 accepts two level sensor inputs and provides one latching 16A relay for automatic fill or empty control. The optional flash alarm brings attention to level alarm conditions. Package this level controller with our liquid level switch sensors and fittings.


  • Fail-safe relay control of pumps or valves with 0-60 second delay
  • Optional strobe brings immediate attention to level alarm conditions
  • PP enclosure rated NEMA 4X with swivel base for conduit alignment
  • Easy setup with LED indicators for sensor, power and relay status
  • Invert switch changes relay state from NO to NC without rewiring
