Stage Discharge Measurement

Stage Discharge Measurement

Water discharge in rivers and streams is commonly estimated from the measured water-surface elevation (stage) using an empirical fit to measurements of stage and concurrent discharge. NexSens data collection and telemetry systems automate the process of gathering discharge data using this method.

Mast-Mount System

Mast configurations can be mounted above flood stage to accommodate all data logging and communications equipment, simplifying mounting and installation.

Data Collection

NexSens data loggers support a wide variety of analog and digital inputs. Water level readings are sampled and logged with a time and date stamp.

Wireless Communication

Radio, cellular, Ethernet, Wi-Fi, or Iridium satellite telemetry options deliver real-time data from local and remote locations to your computer or mobile device.

Water Level Sensor

The NexSens AccuStage water level sensor is a completely self-contained vented pressure transducer. A vent tube in the cable automatically corrects for changes in barometric pressure, offering +/- 0.1% full-scale accuracy.

Real-Time Flow Data

Point discharge measurements can be obtained using a handheld velocity meter and entered into a rating curve table. Measured water level can then be used to calculate real-time stream flow data.

System Expansion

Fluorometers, multi-parameter sondes, temperature strings, weather sensors, depth sonar, and many other sensors are easily added to the system.

Software and Data Management

Using iChart Live software and the optional WQData Live Web datacenter, project members can quickly access real-time water discharge data for further analysis.

Startup Support

Application engineers are available for training and technical support, both by phone and in person. Our extensive field experience helps ensure seamless implementation of the monitoring project.
