Flowmeter Impact from Changing Pressure

  • #1
I have an argon piping system. The pressure is set at 50 psi. Assume no pressure drop. I have a flowmeter that is calibrated to run at 25 psi. Basically, I want to know what the "new" scale will be on the flowmeter as a result of the increased pressure (from 25 to 50 psi).

In other words, if the meter reads 100 SCFH @ 25psi, what would/should it read at 50 psi?

Depends entirely on the type of meter, some will remain correct..
The manual should have the calibration procedure?

No, this one unfortunately is calibrated only for 25psi. Any deviation will result in needing a correction factor.
