Description

The WL420 water level transmitter, part number 8801801005, is a reliable solution for water level monitoring with a 1m measurement range and 5m cable. This model is suitable for applications involving rain water collection systems like Blue, or Green, Roofs that are designed to collect rainwater and release it at a controlled rate to reduce the peak flow rate into local drainage systems. Green Roofs tend to have less control over the run off and just try to limit the drainage flow, whilst Blue Roofs will collect the rainwater and then control the flow rate into local drainage systems

Application

• Monitoring in Green Roof Systems:
  • Monitoring water levels in Green Roofs allows for better control of the outflows.
  • Level monitoring can also ensure the plants and substrate aren’t washed away by high levels
  • Green Roof water levels tend to be shallow (commonly up to 15cm) but intensive Green Roof can be much deeper.
• Monitoring in Blue Roof Systems:
  • Monitoring water levels in Blue Roofs allows for better control of the outflows.
  • Preventing flooding from sudden heavy rainfall by holding, or restricting the drainage into local water sources.
  • Blue Roof water levels tend to be shallow (commonly around 100mm) for structural protection of the building, but main include holding areas where depth can be higher to aid pumping operations.
