Rotary vortex flowmeters and vortex street vortex flowmeters
Thread Content
Both the progressive vortex flowmeter and the vortex street vortex flowmeter are flowmeters designed based on fluid mechanics, but their structures are different. The swirl-type vortex flowmeter causes the uniform fluid in the pipeline to rotate as a whole, thereby generating vortices, which allows for a direct measurement of the total flow rate. On the other hand, the vortex street vortex flow meter inserts a sensing element into the fluid, and detects the overall flow rate by measuring local vortices. The former has high pressure loss and is suitable for flow measurement in pipes with a diameter of less than 150 mm. The latter has low pressure loss and is suitable for measuring large pipe diameters and high flow rates. Rotating vortex flowmeters are currently used only for measuring gases. Vortex street vortex flowmeters can measure liquids, gases, and steam.
Using a rotary vortex meter is better for measuring natural gas, as it can handle large pressure differences
What is the difference between a rotating vortex and an ordinary vortex? And what is its relationship with vortex flow meters? Please ask the original poster to help clarify this. .
