Flowmeter Impact from Changing Pressure

Click For Summary
The discussion focuses on the impact of increased pressure on a flowmeter calibrated for 25 psi when the system pressure is set to 50 psi. It highlights that the new reading at 50 psi will depend on the type of flowmeter used, as some may remain accurate while others will not. Since the flowmeter in question is only calibrated for 25 psi, any deviation from this pressure will require a correction factor to obtain accurate readings. The manual does not provide a calibration procedure for the higher pressure. Accurate flow measurements at the new pressure will necessitate adjustments based on the specific characteristics of the flowmeter.

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.
 

Thread 'Is energy really conserved?'

I built a device designed to brake angular velocity which seems to work based on below, i used a flexible shaft that could bow up and down so i could visually see what was happening for the prototypes. If you spin two wheels in opposite directions each with a magnitude of angular momentum L on a rigid shaft (equal magnitude opposite directions), then rotate the shaft at 90 degrees to the momentum vectors at constant angular velocity omega, then the resulting torques oppose each other...
