Vortex flowmeter parameters and measuring medium

The vortex flowmeter is a type of velocity flowmeter. Its working principle is based on the Karman vortex principle. It can measure gas, liquid, and steam media. In most cases, it mainly measures gas media and is widely used in petroleum. , chemical industry, electric power, light industry, power heating and other industries. The output of the vortex flowmeter is a pulse frequency, and its frequency is linear with the actual flow rate of the fluid being measured. There is no drift in the zero point, stable performance, and various structural forms, including pipeline type and plug-in flow sensors.
