MEASURING PRINCIPLE

The vortex flowmeter is based on the principle of Karman vortex street (Karman vortex street) for measurement. When the fluid passes through the baffle, vortices with opposite rotation directions alternately appear on both sides. Each vortex will produce a low pressure zone, the vortex sensor detects the pressure change and converts it into an electrical pulse signal. The vortex flowmeter measures the flow of liquid, gas and steam by detecting the frequency of the alternating flow of vortices from the baffle. According to proven laws and physics, the frequency of vortex shedding is proportional to the flow velocity.

APPLICATION

Vortex flow meter is always used in measuring steam with high temperature, it also can be used in most kinds of gases like nitrogen, methane, hydrogen, air, compressed air. Because of its accurate measurement, it can also be used for gas trade settlement.

It can also measure liquids. We should pay attention to avoid vibration while use vortex flow meter.
