Volume flow meter unaffected by gaseous medium components
Thread Content
Question: Which type of positive-displacement flow meter is suitable and not affected by the components of the gaseous medium? Flow meter at the outlet of the circulating hydrogen compressor in the hydrogen peroxide plant – currently a Rosemount vortex flow meter is being used. The ratio of nitrogen to hydrogen in the fluid changes frequently; when the proportion of hydrogen is high, the flow rate drops significantly. I am looking for a volume flow meter that is not affected by the composition of the fluid
Metal tube float flow meter, but it is highly affected by pressure
A mass flow meter could be considered
In that case, a positive displacement flow meter should be chosen. This type of flow meter offers high accuracy, but its price is also much higher than that of other differential pressure flow meters or vortex flow meters
Select a differential pressure flow meter with temperature and pressure compensation
Are there gas flow meters that are not affected by changes in composition? Using a component analyzer to determine that the medium density is known, and making corresponding corrections is the correct approach.
