Turbine

The working principle of a gas turbine flowmeter relies on the conversion of kinetic energy from a moving gas into mechanical rotation. As the gas enters the meter, it is directed through an internal flow conditioner to stabilize the stream before it strikes the blades of a free-spinning turbine rotor. The velocity of the gas exerts a force on these blades, causing the rotor to spin at an angular velocity that is directly proportional to the flow rate of the gas. This rotation is detected by an external electromagnetic pickup or a mechanical sensor that counts the revolutions, translating the mechanical motion into a digital pulse or an analog signal. By integrating these pulses over time, the system accurately calculates the total volume of gas passing through the pipeline, making it a highly effective tool for high-accuracy measurement in industrial and custody transfer applications.
