LUGB Series Vortex Flow Meter
Using Karman vortex technology, this flow meter accurately measures steam, gases and low-viscosity liquids like water and gasoline.
Key Benefits:
No moving parts, minimal wear;
Easy installation & maintenance;
Multi-parameter measurement with optional configuration of temperature/pressure transducer (temperature/pressure);
Long service life.
Working principle:
A non-streamlined vortex generator is installed inside the flowmeter. When fluid passes through, two rows of regular vortices are alternately generated on both sides of the vortex generator, which is known as the Karman vortex street. The frequency of the vortices is proportional to the flow velocity. The volumetric flow rate of the fluid is obtained by detecting the vortex frequency through a built-in sensor.
