NexSens RiverGage Radar Level System

Details:

The NexSens RiverGage is a bridge-mount water level measurement system based on cutting edge radar sensing technology and reliable data logging. This downward looking system provides quick and easy (on-bridge) installation with no need to enter the water. The radar level sensor is ideal for monitoring in remote areas and applications where conventional level measurement systems are not suitable. Eight D-cell alkaline batteries power the system for months or an optional solar pack is available for continuous, long-term operation.

A sampling rate of 16 Hz (16 measurements/second) with 20 second averaging minimizes effects of water surface conditions, such as waves and turbulence. The RiverGage sensor is unaffected by air temperature, wave action, humidity, flood events, floating debris, or contaminated water. This highly accurate radar sensing technology meets USGS guidelines for water level detection and will not drift over time. Discharge (flow) is calculated based on manually-entered stage/discharge rating data.

The RG500 RiverGage system consists of a NexSens SDL500 Submersible Data Logger, OTT RLS Radar Level Sensor, and 10m sensor interface cable. The RG500C real-time cellular telemetry system also incorporates a built-in modem and high gain antenna. The real-time system can be configured for any of the major cellular networks, including Verizon, AT&T, or Sprint Nextel. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to a RiverGage system or network of systems.
