Regarding density compensation issues in gas measurement
Thread Content
When using a differential pressure flowmeter to measure gas flow, many current flow totalizers can be equipped with temperature and pressure compensation functions. But there is no compensation for density, but in actual circumstances, I think density must also be compensated. Because there is density in the flow calculation formula? ?
How big will the error be if there is no compensation?
I think temperature and pressure compensation means density compensation.
You can first measure the volume under standard conditions, and then multiply the volume by the density under standard conditions to get the total mass flow rate.
