The measuring principle of vortex type is that the frequency of the Karman vortex generated behind a columnar object in the flow is proportional to the flow velocity. Liquid, gas, and steam can be measured. Compared to throttle flowmeters, vortex flowmeters have a simple structure, wide rangeability, and cost advantages. Vortex flowmeters have a unique sensing structure that integrates a vortex shedder bar and vortex sensing sensor, and proprietary signal processing technology, which enables stable flow measurement over a long time from high-temperature fluid to cryogenic fluids.
The reducer type with integrated reducer (shrinking and expanding tubes) is suitable for lines with large seasonal flow fluctuations, such as steam supply lines.
The multivariable type with a temperature sensor built into the vortex shedder bar is also suitable for steam measurement.
