The flow of the medium is directed at the turbine wheel in the axial direction and so rotated. The speed of the freely turning wheel over a wide range is directly proportional to the average flow velocity.

Turbine flowmeters are used mainly for applications with lubricating and non-lubricating media. They are especially well suited for the flow rate measurement of low and medium-viscosity liquids such as water, emulsions, glycol mixtures, and light oils. Measuring cryogenic liquids is possible as well.

Numerous process connections are available due to the flexible design.
