The British designed and manufactured BDT is an award winning and industry proven level monitoring device that has been specifically designed for sewer and drain monitoring. BDTs are normally installed underneath existing manhole covers in areas at risk from blockages. Wireless technology makes BDT installation easy, with minimal disruption and without the need for cables.
The is a proven alternative to using ultrasonics for real-time blockage and surcharge detection in sewers, storm drains, tanks and wet wells. Unlike ultrasonic transducers which are difficult to programme and consume vast amounts of energy, the BDT is easy to use as it does not require programming. Further, the energy required is just 1/50,000 compared to that of as typical the ultrasonic.
Bulk Dielectric Transducer Technology has no moving parts, is easy to install often without the need for confined space entry teams. Normally supplied with a wireless transmitting head unit the BDT plus its radio can enjoy a battery life of up 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.
The BDT can also be used as a flood alarm. In this application it has many advantages as there are no moving parts to become snagged by spiders webs of debris, further the BDT self tests. In flood applications the BDT can be interfaced with a variety of radio systems enabling communication over distances of up to 100km,
– Detecting Blockages in Sewer Networks – Wet Well High Alarms
– Sewer Surcharge Monitoring – Storm Drain Monitoring
– Industrial & Commercial Sewer Alarms – Basement Flooding Alarm
– Wide Area Flood Alarms – Community Flood Alarms

The BDT MKII was introduced in the summer of 2014, featuring a brand new injection mounded housing in water repellent HEDP and enhanced immunity to FOG and ragging. The MKII BDT is fully compatible with existing Gateway Receivers and Booster/Repeaters.
The MKII BDT has has already been installed in hundreds of locations both in the Utility and Industrial / Commercial sectors.
For small domestic and commercial applications there is also a compact version of the BDT called the BDT Lite.
In 2015 a new high power version of the BDT will be introduced capable of communicating directly from a manhole cover over a distance of up to 500m. Above ground there is an even high power version that can be used for flood monitoring that has a range of up to 100km.
The High Power BDT is ideal for use on large industrial sites requiring 24/7 real-time monitoring of sewers and wet wells.
