Overview
The Onset 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.
Mechanics
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.
Benefits
- 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

Lake Erie Volunteer Science Network: Building Trust in Citizen Science Programs
Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question.

Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. 
 
Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit.

Lightweight and easy to use, the SonTek CastAway offers a convenient 3-in-1 solution for measuring conductivity, temperature, and depth profiles. At a 5 Hz sampling rate, the CastAway is designed for up to 1 m/s free-fall through the water column. 
 
 With fast response and accurate conductivity, temperature, and depth measurements, the CastAway is ideal for thermocline and halocline profiling. The unit also reports salinity and speed of sound.
