Flow Measurement


The vortices cause a small sensing element either behind or within the shedder bar to oscillate back and forth at a specific frequency. The velocity of the working fluid is directly proportional to this frequency of the vortices generated by the shedder bar’s unique geometry. With the known cross sectional area of the pipe, volumetric flow can be calculated.

Often Vortex flow meters will also utilize a pressure and/or temperature sensor to achieve a compensated mass flow measurement.

Turbine flow meters are cost-effective and offer reliable, measurement with minimal flow meter maintenance required.

Von Kármán Effect


Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect, which states that when flow passes by a bluff body, a repeating pattern of swirling vortices is generated.

In a Vortex flow meter, an obstruction in the flow path, often referred to as a shedder bar, serves as the bluff body. The shedder bar causes process fluid to separate and form areas of alternating differential pressure known as vortices around the back side of the shedder bar.

 Turbine flow meters for Gas

​Turbine meters are simple to operate and maintain, and in service worldwide as a reliable, cost-effective method for achieving accurate flow measurement. Turbine flow meters are designed to maximize throughout and minimize pressure drop, maintain high flow rates over an extended flow range and offer pulse output that is linear to the flow rate. The turbine meters also minimize fiscal measurement uncertainty by delivering high-frequency pulse resolution to account for minute increments of the flow rate.
