WLC3000 – Fill Only

WLC3000 – Fill Only

Complete Kit Includes:

  • Sensor With 50 ft. Sensor Wire*
  • Controller
  • Mounting Assembly


  • 4-wire Dry contacts to BMS for measuring:
    • Fill “ON” time
    • fault conditions
  • Operates any 110VAC valve. (Not supplied in this kit…see Options Section for valves)


There are many applications where a fill only control can be used. Typically, these environments will not require a BMS connection or the high and low alarms. These applications just need a long-life dependable workhorse to keep them full and this is the ideal product for that.


There are three outputs which:

  1. Close a set of dry contacts for a BMS
  2. Operate a relay rated at 30AMPS for 250VAC
  3. Turn on an LED to indicate this sensor has tripped.

The Fill dry contacts can be used as a comparative to develop a baseline benchmark of water usage for the system.

*Custom Sensors lengths available upon request.
