Doppler Radar – Surface Flow Sensor

Our Doppler Radar Surface Flow Sensor is the ideal sensor for all applications in water flow monitoring and measurement applications. It is particularly suitable for flow measurement in open flumes, rivers and lakes as well as coastal areas. It is an economical solution through versatile and simple mounting options. The flood-proof IP 68 housing ensures a maintenance-free permanent operation. The usage of remote sensing technology eliminates the installation, corrosion & fouling issues associated with submerged sensors. Additionally, accuracy and performance are unaffected by changes in water density and atmospheric conditions.

The Radar Doppler Surface Flow Sensor can be interfaced to either our Water Level Gauge or to the ULS UltraLab Advanced Field controller. For applications where directional surface flow information is needed, a dual Radar Doppler Surface Flow Sensor set and an additional  software module are necessary.
