WL420 Level Transmitter

Description

The WL420 water level transmitter, part number 8801802505, is a reliable solution for water level monitoring with a 2.5m measurement range and short 5m cable. This model is ideal for applications involving rain water collection systems like Sustainable Drainage Systems (SuDs) that try to mimic natural water drainage instead of immediately channelling rainwater into local water courses. Suburban areas often have increased impermeable surfaces (roofs, roads and driveways), which generate more runoff. SuDS help mitigate this, reducing the risk of localised flooding.

Application

  • Wastewater Treatment (Primary Settlement Tanks):
    • Monitoring the liquid level in primary settlement tanks at wastewater treatment tanks.
    • Preventing overflows and controlling pump operation.
  • Monitoring in Rainwater Runoff Systems:
    • Monitoring water levels in Sustainable Drainage Systems to ensure the systems are large enough for the local area.
    • Preventing flooding from sudden heavy rainfall by delaying it draining into local water sources.
    • SuDS features, such as rain gardens and swales, can create habitats for wildlife.
