Integrating High-precision Gas Turbine Flowmeter Accurate Measurement Gas Volume Flow

The LWQZ series intelligent gas turbine flowmeter is suitable for measuring various gases in the gas and industrial fields, such as natural gas, city gas, propane, air, nitrogen, etc.

The instrument has high accuracy and good repeatability, making it an ideal instrument for gas metering in petroleum, power, metallurgy, industrial and civilian boilers, as well as for measuring urban natural gas, gas pressure regulating stations, and gas trade.

Working principle:

The working principle of LWQZ intelligent gas turbine flowmeter: the measured gas entering the instrument is accelerated by the flow guide body with cross-sectional contraction, and then acts on the turbine blades through the inlet channel, causing the turbine to rotate; The turbine speed is proportional to the volume of the measured gas and the magnetic resistance of the sensor is periodically changed by the magnet on the rotating transmission disk, so that the sensor outputs a pulse signal proportional to the fluid flow rate.
