Working Principle of Gas Turbine Flowmeters

Working Principle of Gas Turbine Flowmeters

Gas turbine flowmeters operate on the principle of fluid dynamics, specifically the interaction between the flowing fluid and a set of rotating turbine blades. The flow of the liquid or gas causes the turbine blades to rotate at a speed proportional to the flow rate. This rotational motion is detected by sensors, which convert it into an electrical signal. The frequency of the electrical signal is directly proportional to the flow rate, allowing for accurate measurement.
