Sewer Blockage and Surge Detection wireless transmitters are an award-winning and widely used alternative to using ultra sonics for real-time blockage and surcharge detection in sewers, storm drains, tanks and wet wells.

Using Bulk Dielectric Transducer (BDT) Technology the unit has no moving parts, is easy to install, easy to set up and thanks to its low power consumption has a battery life of 10-years in spite of broadcasting data every 2.5 seconds.

The BDT is ideal for drive-by monitoring or fixed networks where messages can be delivered to existing SCADA, remote data servers or interfaced with BMS/telemetry over distances of many km using our Network Boosters, Gateway Receivers or Cellular Data Concentrators.

Areas the BDT can be used.

  • Detecting Blockages in Sewer Networks
  • Wet Well High Alarms
  • Sewer Surcharge Monitoring
  • Storm Drain Monitoring
  • Industrial & Commercial Sewer Alarms
  • Basement Flooding Alarm
