vortex flowmeter
Description of vortex flowmeter
vortex flowmeters, flow meters to measure the volume of gas, vapor or liquid volume flow, volumetric flow or standard conditions of mass flow rate based on Carmen (Karman) vortex principle. And as a flow transmitter used in automated control systems Vortex.
