* 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.
Measurement accuracy also depends on temperature response time.

The cost-effective HOBO MicroRX station is ideal for flood alert system, storm water monitoring, irrigation, hydrological research, and environmental applications. Pre-programmed water flow formulas and a stage discharge table result in easy and intuitive configuration. Spend more time focusing on results, and less time on configuration and data access.
Key Features
- Keep updated with changes in water level as they occur - real-time alerts via text message & email
- Eliminate complicated manual calculations - pre-programmed water flow and accumulated rainfall formulas trigger immediate notifications of critical water level conditions
- Powerful web-based access to your data - with LI-COR Cloud web-based software: view and manage your water level measurements, configure alarms, create custom dashboards
- Reduce maintenance visits - non-vented water level sensor, with a choice of four ranges
- Station-side alarms - for water flow and accumulated rainfall triggered at time of measurement
- Expandable - add up to five additional sensors to monitor other parameters such as rainfall & soil moisture (comes with integrated barometric pressure sensor)
-
Solar and battery power options:
- Model RX2104 - Integrated 1.7 W solar panel with rechargeable battery pack (for extra solar power, a 5W or 15W external solar panel can be added to the RX2104)
- Model RX2103 - User-replaceable AA lithium batteries
- Up to 10-minute connection rates - via 4G cellular data plans
- Built tough - compact IP66/NEMA 4X enclosure
- Easy integration - can provide provide an automated data feed to AQUARIUS Analytics Software for Water Environments.
Requires an RX data plan (see options above), which must be renewed annually. The station comes with a SIM card installed; you can use your own if needed.
