Product Overview
The HFS Vortex Flow Meter operates based on the vortex precession principle. When fluid passes through a vortex generator, vortices are formed and forced to rotate within a Venturi tube. Flow measurement is achieved by detecting the precession frequency of these vortices, which is proportional to the flow rate.The device is suitable for gaseous media such as natural gas, liquefied gas, and air. With self-conditioning flow characteristics and strong anti-interference capability, it is widely used in medium and small-scale natural gas measurement, boiler and burner gas metering, and industrial process gas measurement applications.
