The floodwater sensor unit, integrated into the pump, uses three conductive probes – a pump start probe, a pump stop probe and a common probe for measuring conductivity between the other probes.
Control unit
The wall-mounted control unit recognises conductivity between the probes. If water is detected between the common probe and the pump start probe, the control unit will automatically activate the pump and will deactivate it when the water level drops below the pump stop probe.
The control unit has a green LED to indicate mains power is on and a red LED indicating the pump is active.
Stainless-steel pump
The pump operates at a typical flow rate of 140 litres per minute at a 3-metre head. There is an option to install a larger capacity pump if required.
