Is the vortex flowmeter the best instrument for measuring gas flow?
Thread Content
Upon arriving at the design firm, I was tasked with designing an instrument system for a chemical plant. There is a gas flow measurement system, and I’m not sure which type of gauge would be the best choice – the priority is high accuracy, as it will be used for trade measurements. Basic requirement: Pipe, DN100 ； Pressure 2.5Mpa; Temperature 30 degrees ； Components: N2+H2; Range: 2500~8000 NM3/h. Please help recommend a suitable flow meter.
For trade measurement, the accuracy may not be sufficient; it is recommended to use a mass flow meter
Can a mass flow meter be used for gases?
Yes, there are ones that can measure gases.
If the medium composition is stable, it is recommended to use a mass flow meter
Use a thermal gas mass flow meter.
Using imported vortex flowmeters can ensure accuracy. Like Rosemont’s
Use E+H. The purified air supplied for use in our equipment here all uses E+H vortex flow meters. The effect is pretty good.
May I ask: What gas is the purification air? Is a good effect equivalent to high precision?
Turbines are relatively good instruments for measuring gas flow rates, offering good sensitivity, accuracy, and measurement range.
A turbine flowmeter is the most accurate; it is commonly used for natural gas measurement abroad
