 Gas turbine flow meter is a precision measuring instrument used for gas flow measurement.
It has small pressure loss, high accuracy, and low dynamic flow, great anti-vibration and anti-pulsation performance, wide range ratio, excellent low and high-pressure measurement performance, multiple signal output methods and low sensitivity to fluid disturbances.

Gas turbine flow meter take into account the compressibility of gases, and the correlation between volume, temperature and pressure of the medium. To convert Process Condition medium to Standard Condition, temperature and pressure sensors are added to track temperature and pressure changes of the measuring medium.

Gas turbine flowmeters are widely used in gas metering and gas pressure regulating stations for petroleum gas, chemical gas, electric power and industrial boilers, as well as gas transmission and distribution pipeline networks, urban natural gas metering. It is the preferred instrument for trade settlements.
