The HOBO MicroRX Water Level Station is a cellular, web-enabled water level monitoring solution for stormwater, floodwater, irrigation, hydrologic, and environmental applications. Pre-programmed water flow formulas for select weirs, flumes, and a stage-discharge table result in an easy and intuitive configuration.

New water flow and accumulated rainfall calculations, which are performed directly on the station at the time of measurement, trigger immediate notifications of critical water level 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.

*
Water Level Accuracy With accurate reference water level measurement, known water density, and a stable temperature environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected sensor Water Level Accuracy.
**
Raw Pressure Accuracy Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
***
Changes in Temperature Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes.
Note Measurement accuracy also depends on temperature response time.
