Description

Overview

Enabled with cellular communication, this award-winning remote water level monitoring station completes calculations onsite and sends notifications of critical conditions via cellular plans to the cloud. Ideal for stormwater, floodwater, irrigation, hydrologic, and environmental applications, this remote monitoring solution comes with pre-programmed water flow formulas for select weirs, flumes, and a stage discharge table that allow easy and intuitive configuration.

This compact and durable station, together with the non-vented water level sensor, provides reliable monitoring, even when deployed in harsh conditions. 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 optional integrated solar panel or battery power, with a wide range of plug-and-play smart sensors, supports flexible environmental monitoring.

Features

  • 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

* 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.
