Which flowmeter is more accurate for measuring nitrogen?
Can AK-LUGB vortex flowmeter, temperature and pressure compensation liquid crystal display instantaneous cumulative flow meter
If the volume flow rate is measured (m3/h, m/s), the vortex flowmeter is best. The accuracy is quite high, and the cost performance is good. However, if you use the vortex flowmeter to measure it, you should pay attention to the range of measurement.
If mass flow measurements are used, a gas mass flowmeter may be used.
Volume flow measurement, can also use the differential pressure flowmeter and orifice plate flowmeter, vembar, Annubar flowmeter. But the accuracy is slightly lower and the price is more expensive. Its advantage is that it can measure the flow of gas-liquid two-phase medium (e.g., gas liquefaction or gas-liquid two-phase flow due to high pressure).
