What is 2” natural gas meter?
2” natural gas meter means 2 inch size or we can say DN50 flow meter to measure natural gas flow rate and total flow. Turbine flow meter is acknowledged a perfect flow meter for natural gas.
Gas turbine flowmeter is actually a device used to detect the flow rate and flow of gas in a gas pipeline in a closed state, and it is a typical velocity flow meter. Gas turbine flowmeter has the advantages of high measurement accuracy, high flexibility, small and compact volume, simple operation, and low failure rate. It is the mainstream gas measurement device in the field of gas measurement. 2” natural gas flow measurement is a normal request for turbine flow meter.
With the deepening of understanding, the application of flow meter has gradually expanded to oil fields, chemical industries, and urban natural gas projects. It is a very ideal gas measurement instrument so far.
Principle of 2” natural gas meter
2” Turbine flowmeter for natural gas is a speed flowmeter composed of turbine, sensor, preamplifier, induction coil, housing, etc. The flowmeter's impeller rotates under this force as natural gas enters the gas stream mounted on the duct. The rotational angular velocity of the turbine wheel is proportional to the gas flow over a range of flow rates. Therefore, the gas flow rate can be obtained from the rotational angular velocity of the turbine, and thus the gas flow through the turbine flow meter tube can be calculated. Turbine flow meter is widely used in measurement of petroleum, natural gas, biogas, LPG gas, light hydrocarbon gas and other gases. In the natural gas industry, it has gradually become the preferred handover of industrial gases and measuring instruments for urban gas in my country. In the calibration of turbine flowmeters, we found that in addition to the normal measurement deviation of the system caused by the structure of the flowmeter itself, most turbine flowmeters have different degrees of wear, corrosion and clogging during the verification period, whichn cause of error of natural gas turbine flow meters.
