Blocked Sewer and High Level detection and sump pump monitoring made easy! The BDT is simple to install proven technology that can deliver real-time Blocked Sewer / High Sewer Level Alarms, High Level Sump Alarm messages without cables to existing alarm panels, BMS, SCADA, or over a Wide Area Network to Mission Critical IoT and via Satellite SBD messaging services.
The BDT is a unique and innovative and since its debut in 2010 has won multiple industry awards.
Unlike float switches that can get held down by FOG or wet wipes etc the BDT is a system that is designed to detect high levels using a bulk dielectric transducer principle, thus will fail safe if fouled.
However, unlike other dielectric based sensors on the market, the BDT has been optimised to be operated for up to a decade on a single battery pack. It is also 100% water proof, includes an integrated wireless transmitter head and is declared for conformity to ATEX Zone 2 to mitigate the risk of explosion due to sewer gases, etc. that can occasionally build up in sewers and sumps.
The BDT is supplied with 2m or 4m of cable which separates the BDT Transducer and the Transmitter Head Unit. The head unit is normally mounted from the surface just below the manhole of the sewer or sump cover and secured in place using stainless steel screws. The cable is then tied up to set the depth of the transducer and hence the trigger point and the job is compete.
