Vortex flow meters operate by generating vortices as fluid passes through a pipe containing a columnar object. When vortices hit a vortex detector, it generates voltage signals that are then used to calculate the flow rate in liters per minute (LPM). The frequency of these signals is directly proportional to the flow rate, allowing for accurate measurement.


The piezoelectric ceramic can be assembled to be used as a detector to sense vortex frequencies to calculate the flow rate (LPM=l/min).

Features of vortex flow meters

•Measurements of a wide range of substances, including liquids, gases, and steam

•A cost-effective solution with low installation costs

•Good accuracy in flow rate measurement

•They exhibit a linear response to changes in flow.

•Vortex flow meters are not affected by variations in pressure or temperature, ensuring consistent performance.

Depending on the specific configuration, vortex flow meters can accurately measure flow rates as low as 2 LPM and as high as 180 LPM
