Automated Staff Gauge River Level Transmitters

Cosmetically designed to look like nothing more than an ordinarily staff gauge, the RDNET1000 Wireless River Staff Gauge offers industry leading performance when it comes to automated river level measurement and alarm generation.

Already employed by the NHS and others to protect some of the UK’s most critical strategic sites, the wireless staff gauge offers significant performance advantages over its GSM rivals, including real-time messaging, improved battery life, 100% cyber attack immunity and automated health messaging.

With the choice of set point BDT type sensors, analogue or SDI-12 pressure transducers, systems can be constructed to monitor depth in streams and rivers from just a few cm depth to many meters, with data reporting back to a Gateway Receiver, local PC, BMS system or telemetry outstation in real-time.

Dual and triple redundancy options exits satisfying those critical industry sectors such as heavy industry, rail and nuclear. The staff gauges are fabricated in high quality weather resistant GRP and can be supplied in lengths from 1m to up to 6m. Scaling on the outside of the staff gauge can be metric or imperial.

Additional features include and integrated temperature monitoring to raise an alarm in the event of ice formation which could damage the level transducer and tamper. The latter is considered key by customers when installing gauges in public areas, where an instant tamper message is broadcast if the gauge is subject to a significant shock, removed or tilted.
