We have a small steam leak in the upstream sensing leg of our steam export (750°F, 640 psig) billing meter, causing it to read low. It is before the isolation valve, and appears to be fragile (the leak is under insulation), so it will not be repaired until an outage. I'm drawing a blank, is there a way I can determine the effect of a steam leak on the downstream static pressure in the sensing leg? I have calculated the flux through a potential leak, I just need to figure out how that will affect the pressure at the transmitter, so I can determine the approximate leak size and be able to calculate a corrected flow.
