Gas Vortex flow meter

Gas Vortex flow meter

Gas vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.
If a trigonal column vortex generator is set in the fluid, regular vortexes are generated alternately from both sides of the vortex generator, which is called Karman vortexes. The vortexes are arranged asymmetrically in the downstream of the vortex generator.

IP65 vortex flowmeter is a volume flowmeter which measures the volume flow of gas, steam or liquid, the volume flow of standard condition or mass flow according to Karman vortex street principle. It can be used as a flow transmitter in automatic control system.

The instrument uses advanced differential technology, with isolation, shielding, filtering and other measures, to overcome the similar products of poor earthquake resistance, small signal data disorder and other problems, and uses a unique sensor packaging technology and protection measures, to ensure the reliability of the product. There are two types of products: basic type and compound type. Basic type measures single flow signal. It can measure temperature, pressure and flow at the same time. Each type has a monolithic, split structure to adapt to different installation conditions.
It is characterized by small pressure loss, large measuring range and high precision. It is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. No moving mechanical parts, so high reliability, small maintenance. Instrument parameters can be stable for a long time. Vortex flowmeter adopts piezoelectric stress sensor with high reliability and can work in the operating temperature range of -20℃ ~ +250℃. Analog standard signal, digital pulse signal output, easy to use with computers and other digital systems, is a relatively advanced, ideal.
