Monitor water levels and flows from mobiles

A new water monitoring station that measures levels, flows, flumes and stage discharge via cloud networks has been launched to assist in the mitigation of the effects of floodwaters, stormwater, and protect against compromised storage dams.

Distributed by local technology integrator, Euca Technologies, on behalf of one of the world’s leading logging and monitoring system specialist companies, Onset Computer Corporation, the HOBO MicroRX Water Level Station delivers near real-time water level and flow alerts.  The new cellular, web-enabled station uses the same 4G cellular technology widely adopted for mobile devices, to provide fast, reliable communications. Pre-programmed water flow formulas for select weirs, flumes, and a stage discharge table result in an easy and intuitive configuration.


Euca Technologies managing director, Ernest Campling, says the new water flow and accumulated rainfall calculations, which are performed directly on the station at time of measurement, trigger immediate notifications of critical water level conditions, combined with Onset’s ceramic water level sensor, delivers calculated water level and flow data through the powerful cloud-based HOBOlink software for remote reporting and management.

“As a result, hydrologists and others can access their water level data via any web-enabled device to get timely information whenever and wherever they need it. Designed to withstand the harshest conditions, the tough, compact station is available with built-in solar power or battery power.

He explains that the monitoring of water level can be particularly challenging, especially with the need for immediate access to critical data in what are often severe weather conditions. The compact and durable station, together with the non-vented water level sensor, enables harsh condition deployments and reliable monitoring. The optional integrated solar panel or battery power, with a wide range of plug-and-play smart sensors, supports flexible environmental monitoring.

Supported measurements include absolute pressure, barometric pressure, leaf wetness, light intensity, PAR, pulse input, rainfall, relative humidity, soil moisture, temperature, water level and wind


  • Stormwater monitoring – and wetlands monitoring
  • Floodwater mitigation – providing an alert system for potential flood situations
  • Irrigation control – delivering accurate water usage data for conservation, water use records, and water rights issues
  • Hydrological studies – monitoring surface water systems and aquifers, to support water quality and environmental studies
  • Station-side alarms for water flow and accumulated rainfall triggered at time of measurement

The system includes a non-vented ceramic water level sensor with a choice of four ranges, interchangeable, Kevlar-reinforced water level sensor cables, integrated barometric pressure sensor and a compact IP66/NEMA 4X enclosure.

The unit includes a built-in LCD which confirms proper setup and operation and can be powered via solar power and lithium battery packs. It also has inputs for five plug-and-play smart sensors.
