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 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.

  • Station-side alarms for water flow and accumulated rainfall triggered at time of measurement
  • Non-vented ceramic water level sensor with a choice of four ranges
  • Interchangeable, Kevlar-reinforced water level sensor cables
  • Integrated barometric pressure sensor
  • Compact IP66/NEMA 4X enclosure
  • Built-in LCD confirms proper setup and operation
  • Two power options:
  • Integrated 1.7 W solar panel with rechargeable battery pack
  • 5 W and 15 W external solar panels can be added (RX2104 only)
  • User-replaceable AA lithium batteries
  • Inputs for five plug-and-play sensors
  • Up to 10-minute connections rates via 4G cellular data plans
  • Cloud-based monitoring and data access through HOBOlink
  • Available with stainless steel or titanium sensor ends
  • 3-point NIST-traceable calibration certificate included for the water pressure sensor

  • "Operating Range: RX2103: -40° to 60°C (-40° to 140°F) RX2104: -20° to 60°C (-4° to 140°F)"
  • Smart Sensor Connectors: 5
  • Smart Sensor Network Cable Length: 100 m (328 ft) maximum
  • Smart Sensor Data Channels: Maximum of 15 (some smart sensors use more than one data channel; see sensor manual for details)
  • Logging Rate: 1 minute to 18 hours
  • "Time Accuracy: ±8 seconds per month in 0° to 40°C (32°F to 104°F) range; ±30 seconds per month in -40° to 60°C (-40° to 140°F) range"
  • "Battery Type/Power Source: RX2103: 6 AA 1.5 V lithium batteries or AC power adapter (P-AC-1) RX2104: Integrated 1.7 watt solar panel and NiMH rechargeable battery pack; optional AC power adapter (P-AC-1) or external solar panel (SOLAR-xW) can be used in place of integrated solar panel"
  • Battery Life: RX2104: Typical 3–5 years when operated in the temperature range -20° to 40°C (-4° to 104°F); operation outside this range will reduce the battery service life.
