Linear velocity sensor SVS

DopplerIP67non-contact

HyQuest Solutions’ SVS is a contact-free surface velocity sensor for open channels and rivers. The sensor uses innovative radar technology and enables reliable, non-contact measurement without the need for structural work in the water. With its very low power consumption, its high reliability and low maintenance SVS enables the permanent recording of the flow velocity of open channels for long periods of time. It is the ideal sensor for 24/7 monitoring surface water velocity especially in unattended areas. Because contact-free water velocity measurements are unaffected by sediments, mud and floating refuse, the SVS provides accurate results even in flooding situations. SVS is easily mounted on bridges, ceilings of closed channels or any superstructures of the channel. Depending on the condition of the water surface, the device can be installed in a height of 0.5 to 35 m. The SVS transmits a a radar signal to the water surface (at a 60° angle) and receives the reflected signal. By analyzing and comparing both signals the water surface velocity can be derived (principle of Doppler frequency shift). To provide reliable data, a minimum wave height of at least 3 mm is required. Setting and configuration of the SVS can be easily and conveniently done on a PC or laptop via standard terminal programs Non-contact, maintenance-free No structural constructions in the water needed Simple integration into existing system Remains operational in flooding situations
