What are the structural differences between natural gas flow meters and other flow meters?

The density of gas is much smaller than that of liquid, so gas turbine flow meters have some differences in structure compared to liquid turbine flow meters. The density of gas is greatly affected by changes in temperature and pressure. Therefore, when measuring gas volume flow, gas turbine flow meters with temperature and pressure compensation functions are often used to achieve accurate measurement of gas media. When measuring the volume flow, this turbine flowmeter must track and detect the temperature and pressure of the gas medium, and convert the volume flow of gas under different working conditions into the volume flow under Standard state (P=101.325Kpa T=273.15K).

The temperature and pressure compensated gas turbine flowmeter can use the principle of electromagnetic induction to convert the turbine speed into a pulse signal proportional to the fluid volume flow rate. The signal is input into the arithmetic unit after amplification, filtering and shaping, and is processed together with the temperature and pressure signal. The arithmetic unit calculates according to the gas Equation of state, and the results can be displayed locally or transmitted remotely in various signal forms. If the turbine flowmeter adopts various single-chip microcomputer technologies and micro power consumption technologies as the arithmetic unit, in addition to temperature and pressure compensation, it can also have various functions such as alarm self-diagnosis signal remote transmission, achieving strong functionality and computationessenceHigh precision, compact structure, strong anti-interference ability, wide measurement range, and good repeatability. The gas turbine flowmeter can be applied to the measurement of single-phase gas, standard volume total, and is an ideal instrument for gas measurement in industries such as petrochemical, power metallurgy, and urban gas pipeline networks.
