Water Pipe Leak Detection Alarm Type WPLD

Two user adjustable settings are provided, one to set the number of allowable missing litres of water, adjustable between 3 and 20L, the second to set the monitoring time period adjustable between 10 and 40 minutes. The settings allow a leak detection range for a continuous leak between 75ml (3L/40m =75mL) and two Litres (20L/10m =2L).

The WPLD also has a 230VAC output to a water shutoff valve to turn off the supply in the event of a leak being detected. A normally open volt free contact is also provided for onward signalling to a BMS or existing alarm system.
