The WLDS panel monitors the flow of water into a building and sounds an alarm and optionally shuts off the supply should the flow rate exceed preset parameters. It activates when the flow exceeds the pre-set minimum for the pre-set period of time and can identify different flow and therefore leakage rates, in accordance with BREEAM Wat 3. These parameters can be adjusted by the user to allow for different conditions.
For smaller premises and domestic installations please see our WLDS-50 system
IMPORTANT: in order that meaningful parameters are entered, we strongly recommend that a full water audit be carried out in order to establish water consumption trends over a period of time.

Designed to detect major leaks and help prevent flood damage caused by leaking pipes and fittings or by vandalism.
The WLDS-10 panel is connected to a pulse water meter installed at the main intake point of the building and hence monitors the consumption of water. An audible/visual alarm output is activated when a continuous flow of water passes through the water meter at a flow rate above a preset amount for a preset period of time.
A normally open free contact is provided for connection to a BMS (Building Management System) or to activate a local sounder/beacon type alarm.
A normally closed free contact is also provided to shut off the water supply via a solenoid shut off valve if required.
The WDLS-20 has a second pulse water meter installed at the site boundary and in addition can detect a loss of water between the site boundary and the main intake point.
