This type of vortex meter is used for flow and volumetric measurements of conductive and non-conductive fluids, gases and vapours in all industrial branches. Applications include volumetric measurements for balancing ( compressed air systems, heat carriers, vapours, chemical products, for example) , process control and high throughput applications. This instrument uses piezoelectric stress sensors, high reliability, can be -20  ~ + 250  operating temperature range. With analog standard signal, but also digital pulse signal output, easily supporting the use of computers and other digital systems is a more advanced and ideal flow Can be seen from the above equation, VSF output pulse frequency signal from fluid properties and composition changes, that instrument coefficient in a certain Reynolds number range, and only with the bluff body shape and size of the pipe and so on. But as the material balance and energy flow in the measurement of mass flow to be detected, then the flow meter should also monitor the volume of the output signal flow and fluid density, fluid properties and composition of the flow measurement or have a direct impact Vortex flowmeterKarman vortex principle is based on Measurement of fluid flow in closed conduits newFlowmeter Media because of its good ability to adapt, without direct measurement of temperature and pressure compensation can be steam, air, gas, water, liquid volume flow conditions, with temperature and pressure sensor measures the standard volume flow and mass flow conditions, is to cut expenditure
