Flood, River Monitoring, Sewer Flooding Reduction & Systems & Alarms

Flood & River Level Monitoring, Flood Warning, Sewer Flooding Reduction, Flood Alarm, Erosion  and Flood Alarm System.

At Radio Data Networks we do more than generate alarms that are used later to generate autopsy reports! We have created a vast portfolio of sensors, actuators and delivery platforms that enables us to deliver a wide variety of solutions that are applicable across all sectors  from Industry, Housing through to Road and Rail transport.

Uniquely we can also provide systems that not only detect the potential of flooding but in a number of cases can operate autonomously to reduce the risks, especially in the case of the UK’s largest cause of flooding, “sewer flooding”.

Our portfolio if too vast to do justice on any website so always call and ask as many of our solutions are bespoke, designed and built here in the UK to meet customer specific requirements.

Product Portfolio:

• Surface Water Flooding

• River Flooding

• River Level

• Trash Screen Blinding

• Groundwater Levels / Flooding

• Sewer Flooding/ Sewer Surcharges

• Burst Pipe Flooding

• Storm Tank Level

• Failed Sump Pumps

River Level Monitoring:

We offer a wide range of solutions from simple high “OK” alarms through 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, cloud or a remote web server.

BDT Based Automated River Level Alarm / Staff Gauge

High “OK” River Level Alarms

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.
