Radio Data Netorks Ltd have over 30-years of experience in the application of wireless and RFID Technology. They are able to offer turnkey solutions to meet the most challenging demands from virtually any sector of industry from proof of concept through to manufacture. In the past Radio Data Networks have supplied real time wireless remote condition monitoring for the rail, road transport industries, wireless CSO monitoring for the water industry, the remote activation of pollution control valves, vibration monitoring apparatus for machine runtime and fault monitoring, and even wireless lone working systems for equine, along with many more remote monitoring solutions. 


With the wealth of experience to draw upon, Radio Data Networks offer a consultancy service which covers all aspects of custom design from specification through to manufacture and RF test. Radio Data Networks have specialist knowledge in the design of integrated wireless smart sensors, operation at micro-power levels – achieving up to 20-years from a single cell - and can also design systems to work in hazardous areas (ATEX Directive to Zone 2, 1 or to Zone 0 levels).






CSO Monitoring

The services on offer from Radio Data Networks are about being proactive. In the past CSO Spill Monitoring (Combined Sewer Overflow) has been reactionary and informs the owner of an issue. Radio Data Networks employ the commonly used DAM policy of Detect, Alarm, and Mitigate to create real-time systems with fast sampling rates measured in seconds. The ultimate system Radio Data Networks can offer will shut off a CSO discharge point to prevent the blocked sewer incident resulting in a dry weather spill. This system would employ Blocked Sewer Detection (BSD) devices which are detailed on our website and are listed below.

Block Sewer Detection

Blocked Sewer Detection employs the DAM policy formulated in conjunction with European Union environmental bodies to sample typically every 2.5 seconds (RDN1000), and are able to detect sporadic short surcharges which previously went unnoticed. The data is relayed wirelessly either by drive-by or through a fixed network operation (BDT booster) saving the need to deploy engineers, close-off areas and open up manhole covers before knowing the extent of the problem. All real-time results are cross-referenced with rainfall data to assess the risk of an overspill. The ultimate system on offer features advanced low power valve technology, such as the Environmental Innovations FlapstopperTM to contain any spillage until a solution can be found.


Radio Data Networks practices the provision of highly effective remote wireless and smart sensor systems that provide extremely reliable data acquisition for billing and analytical resources. Because of our licenced radio bands we are able to provide a stand-alone wireless system with excellent building penetration bring up to date accurate data to your PC, and from there can be displayed on the web on our data hosting service. Our wireless sub-meters are able to transmit data from 100m to 500m and up to 2km with an external antenna. Our systems easily integrate with existing BMS software packages or similarly can be paired with our Windows Sentinel Software package for graphing, trending and billing etc.

Temperature Monitoring

At Radio Data Networks we provide the necessary control points for all manors of temperature monitoring needs including food safety through temperature monitoring and data logging which is essential to HACCP compliance. Using our durable proven temperature sensor transmitters paired with our highly reliable licenced radio bands we provide a highly effective monitoring and logging service for HACCP and hundreds of other temperature monitoring needs. This system can be visually viewed on our bespoke Windows Sentinel Software for tolerance setting, graphing, logging, trending and can be used to send out alert emails and SMS text.

Flood Alarms

With the threat of flooding on the increase in recent years these flood alarms construct an early warning system. Housed in a descreet bollard package (cut out shown) to allow strategic deployment along river beds and public highways, these self sufficient battery operated units are fully encapsulated to exceed the IP68 Standard in order to withstand prolonged submersion. These low power units are cost effective, unlike GSM/SMS high power consuming systems these BDT devices can exceed ten years of operation, when sending a message every 5 to 15 minutes. These devices can be transmitted over a utility gateway with other CSO devices or a network of up to 64 flood alarms over many square miles (300m to 10km - with a BDT booster); a small utility hub ideal for smaller communities or a centralised GSM/SMS adapted utility hub receiver.
