First, the characteristics of gas turbine flowmeter and spiral vortex flowmeter
Gas turbine flowmeter and screwing vortex flowmeter are the main gas metering instruments in China. In foreign countries, almost no one uses gas to swirl into the vortex flow meter. At present, there are certain applications in the domestic vortex flowmeter. In terms of standard conditions. The international standard ISO9551 promulgated by the International Organization for Standardization and the international recommendations R6, R32 promulgated by the International Organization of Legal Metrology (OIML) have corresponding national standards and regulations in China and developed countries. The above documents guarantee the authority of gas turbine flowmeters in gas metering. Sex. Gas-introducing vortex flowmeters have not yet established relevant standards. It is difficult to guarantee the authority of the flow meter in gas metering. At present, in domestic flow meters for gas measurement, gas turbine flowmeters dominate, and the vortex flowmeters also have a certain market. The use of the two is similar, and users often have doubts about the choice of the two.

The gas turbine flowmeter has good repeatability and is the preferred flow meter for trade settlement. The gas swirling vortex flowmeter is generally repeatable.
The gas turbine flowmeter can obtain very high frequency signals with strong signal resolution. The frequency of the gas swirling vortex flowmeter is very low, and the smaller the diameter, the lower the signal resolution. The measurement error is to be measured.
The gas turbine flowmeter has a wide range, generally 40:1~20:1, and has a wide measuring range, which can be suitable for occasions with large flow changes. When natural gas is delivered, the flow changes are generally large and, therefore, are particularly suitable for natural gas measurements. The latter range is medium, generally 15:1 to 10:1, and the measurement range is slightly narrower. When measuring gas, it is more suitable for occasions where the flow rate does not change much.
In terms of seismic performance, gas turbine flowmeters have better resistance to pipeline vibration. The gas swirling vortex flowmeter is susceptible to pipeline vibration and should be taken care of when using it.
