Our systems can be uniquely configured to detect and report the five common sources of flooding: River; Surface Water; Ground Water; Sewer and Burst Water Pipe. Further, they can be constructed to detect and generate advanced warnings concerning conditions that can contribute to flooding including the blinding of trash screens, failed sump pumps, full storm tanks, heavy rainfall, soil saturation and sewer blockages. Systems can also be built to help mitigate incidents through for example the control of pumps to optimise sewer flows to flattened out peaks to prevent overload surcharges and sewer spills.
We offer a wide range of solutions from simple high/OK alarms though to high precision systems that deliver river depth to mm accuracy. The systems can include multiple measurement points and data can be routed in real-time to existing telemetry, BMS, SCADA, the cloud or a remote web server.
BDT Based Automated River Level Alarm / Staff Gauge
Our simplest and most popular flood sensor our BDT (Bulk Dielectric Transducer) which was first introduced in 2010 for sewer level monitoring.
Unlike float switches which can get trapped by debris the BDT has no moving parts and has minimal hysteresis making it easy to visually verify the set-point. The BDT can be installed in drains, stilling tubes and on river banks within hollow staff gauges and normally is supplied with an integrated wireless communication head unit that contains a sealed for life lithium battery pack with up to 10-years service life.
Systems can be constructed that communicate to existing telemetry, BMS, SCADA, the cloud or a remote web server. Further, they can also include sewer and drainage alarms.
Gateway Receiver with Relay Outputs
We have a range of single and dual redundant telemetry units that can be used to both power and extract the data from 4-20mA, 0-5V or SDI-12 hydrostatic pressure transducers.
