A fill only model will provide a means to keep an environment full of water all the time and is most typically used in a Residential swimming pool or Vanishing Edge pools.


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.
