WLDS 10 & 20

Water Leak Detection Systems

Water Leak Detection Systems

WLDS-10 mk3 and WLDS-20 mk3

British designed and manufactured at our plant in Suffolk the WLDS-10 mk3 & WLDS-20 mk3 BREEAM WAT03 water leak detection systems monitor the flow of water into a building.

If the flow rate exceeds preset parameters an alarm sounds and optionally the water supply can be shut off.

WLDS water leak detection systems activate when the flow of water exceeds the preset maximum for the preset period. It identifies different flows and therefore leakage rates, in accordance with BREEAM WAT03. This gives you flexibility to adjust the parameters to suit your specific conditions.

Features

  • Easy to navigate user interface
  • Accepts inputs from 1, 5, 10 or 100 LPP reed switch type pulse meters
  • Main (M1) & Sub (M2) pulse meters can have different K factors (number of pulses produced per gallon of water)
  • Seven-day clock enables different periods of high flow (HF) to be programmed
  • Peak flow capture enables easy setting of accurate parameters
  • Displays total throughput in litres – useful for parameter setting and water audits
  • Output contact for BMS or optional SB-100 sounder/beacon alarm
  • Output for 24v DC Normally Closed or Normally Open solenoid valve with timed service function
  • Solenoid valve set up enables a Normally Closed or a Normally Open solenoid valve to be selected in software
  • Timed valve service function can be set to reduce the likelihood of valve sticking due to calcification etc.
  • Manual override (protection off) function with adjustable timeout period
  • External alarm input for the connection of ancillary equipment such as tape leak sensing to be interfaced to the water leak detection system
  • Enclosure 300 x 300 x 150mm with a RH hinged door. Facilitates easier wall mounting and access to the internal terminals
  • Alarm test function
  • Tough steel wall mounting enclosure to IP65 protection, optional wall mounting brackets WMB-100
  • Universal 100-240v 50/60Hz input for worldwide use
  • Designed and manufactured in the UK
