HR7350 / HR.FSL-1 Radar Velocity Meter

HR7350 is a velocity measuring instrument using microwave technology which can be used with water level detection for hydrological monitoring. It is designed for surface flow monitoring of natural rivers canals/cules/pipes etc. and flood monitoring in urban flood seasons such as low-lying Ground water drain flow rate monitoring etc. The product absorbs the 24GHz planar microstrip radar technology of InnoSenT from Germany and adopts its own back-end processing technology to accurately extract the water flow speed which can realize non-contact and unmanned automatic monitoring.
