Dedicated to Quality Monitoring for Water Resources

The Water QuB is a monitoring system designed around water resources applications that combines rugged controllers manufactured by Campbell Scientific with sensors used for canal operations, drinking water operations, flood control, well monitoring, or habitat restoration applications. QuBs can stand alone with connected sensors, or be deployed in a networked system to monitor parameters at numerous locations without having to pay for collection at each site. Typical monitored site locations include fields (agriculture), reservoirs, lakes, rivers, streams, springs, bays and estuaries.

Each Water QuB can be deployed with a number of external sensors. Typical sensors include those for temperature, flow, level, weather, (meteorological), and water quality either as individual sensors or packaged together in "multi-parameter" sondes. The signals being measured are likely analog voltage or current, or digital signals consisting of pulse, SDI-12, RTS232/485 or Modbus.

Types of Sensors

Sensor Measures Power Etc
Analog Temperature, pH, Conductivity, Turbidity, etc. 12-24 VDC Most commercial sensors
Pulse Flow 5-24 VDC Common technology for measuring water velocity
SDI-12 WQ (Multi-Parameter), Soil Moisture, Pressure, Flow 12 VDC Increasing number of sensors using this one-wire serial technology
Modbus Gate Position, Industrial Control VAC, VDC Gateway to interfacing with SCADA

Water QuB Host-Remote Station Configuration

The Water QuB site system can include multiple QuB Remote Stations that take their measurements, store them locally and also forward the data to a Host Station for consolidated collection. Each Remote station synchronizes their internal clock with the Host, and uses the clock to know when to turn instruments on and take readings. The radio network is aggressive and robust and can 'repeat' signals to overcome obstructions in line-of-sight pathways to the Host. The Host Station then sends the data to the host server where it is stored and processed for online viewing.

 

QuB is an acronym for "Quality in a Box". The components are chosen for reliability and flexibility in low-power remote deployments. They include data acquisition, data logging, control and communications, and operate in a point-to-multi-point network for cost-effective deployment over a wide area. This powerful, adaptive design means QuBs can be deployed at a lower cost per point because data doesn't have to be collected from each station. Remote stations send their data to "Hosts" over a radio link, and Host Stations store the data for collection using cellular or satellite links. Each type of QuB is built specific for it's application such as environmental, geotechnical or water-related processes. Power and communication configurations are built into each specific installation depending on the project parameters and objectives.

Water QuB

Monitoring systems designed to use sensors most often in water quality, water operations, or habitat restoration applications. This means the signals being measured are likely analog 4-20mA or voltage, or digital signals consisting of pulse, SDI-12, or RS-232. Typical sensors include those for temperature, flow, level, meteorological (weather), and water quality either as individual sensors or packaged together in "multi-parameter" sondes. QuB data sheet

Water Quality QuB

These are self-contained remotely-deployable systems designed to measure "flow-thru" water quality using an array of in-line sensors. Most of these sensors have similar output signals, so many of these monitoring systems differ only by the inclusion or exclusion of a specific measurement type, such as pH, conductivity, turbidity, free-chlorine or ion-specific sensors. WQ QuB's can operate in-line or off-line and may require custom configuration depending on the chosen sensors. Read Water Quality QuB data sheet

Water Quality PAD

A monitoring system designed as a floating platform with sensors deployed in the water column beneath it. Most often these sensors are multi-parameter water quality sondes made by Hydrolabs, YSI or Eureka, but could be anything. The WQ Pads are designed to operate in a Marine environment on solar power alone and can communicate with each other and other floating entities such as dredges so water quality information can be shared in real-time. WQ Pads can be bouys or floating docks. The Pad shown here is stable and large enough to perform maintenance and calibration operations from the deck. PaD data sheet
