Blocked Sewer detection and sump pump monitoring made easy! The BDT is simple to install proven technology that can deliver real-time Blocked Sewer Alarm and High Sump Alarm messages without cables to existing alarm panels, BMS, SCADA, drive beacons and operated sirens can be repeated over both licenced and un-licenced radio spectrum and accessed or posted to the internet.
The BDT is a unique innovative and award winning solution for blocked sewer and clogged sump pump alarm generation. Unlike float switches that can easily fowl on FOG or wet wipes the BDT Lite is a system that is designed to detect high levels using a bulk dielectric transducer. 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.
