Vortex Flowmeters

Vortex Flowmeters (VSF)
Vortex flowmeter (VSF) is a kind of the vibration meters. It simple configuration, and install conveniently. It can measure and control
various liquid (e.g.: water, oil, petroleum, acid, alkali and different chemical fluids) gas (e.g.: air, oxygen, N2, natural gas,
coal gas), and steam (e.g.: saturation steam, overheated water vapor).
SUMMARY
The principle of operation of vortex flowmeter
Vortex Flowmeter is based on a Karmana principle. Flow transmitter is composed of a body with the same nominal diameter and a
column with triangular transect. When a column object placed in flowing fluids ( including gas and liquid ) in pipe, a series of vortexes
will be generated alternately on each side of the object as shown below ( figure 1 ).
