The gas passing through the turbine meter rotates the turbine, whose revolutions are proportional to the gas flow rate.

The revolutions of the turbine are transmitted to the counting mechanism by a special transmission mechanism (it can be mechanical or magnetic).

Turbine gas meters used for commercial gas metering must be three meter diameter lengths (3D) to avoid additional errors due to uneven distribution of gas flow velocities.

These meters, together with the mechanical calculation mechanism, usually have an electrical converter, which can be used to transfer the value of the measured gas volume to the gas volume computer-corrector, which, after evaluating the change in pressure and temperature, the measured with appropriate sensors, calculates the gas volume under normal conditions.

To ensure the reliability and accuracy of gas metering, turbine meters can have several electrical converters and a control wheel that constantly monitors the state of the turbine wheel.
