BEST IN CLASS ACCURACY
Streamflow, or discharge, is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic meters/feet per second or litres/gallons per day. Because stream discharge cannot be measured directly, it must be computed from parameters that can be measured directly, including water level/stage, velocity and the stream or river-bed profile.
With the introduction of radar level/stage and velocity sensors, it is now possible to continuously monitor and therefore calculate discharge using solid state technology. FTS offers a variety of both types of sensors to suite your specific needs.
