Your meter transmitter must be calibrated to compensate for pressure/temperature change to reflect the differing cubic ft per pound at the lower pressure.tm
: : We have a meter that totalizes the 250 psi in lbs/hr. The steam is then reduced to 125 for the plant. Considering that the heat content is different and the volume is also, I'm curious if this effects how it's measured.
: : Does this effect the total amount of steam used?
: : Is 1 lb of 250 psi steam equal to 1 lb of 125 psi steam?
: : Since a pound of feathers and a pound of lead are the same, but that is at atmospheric pressure. Would a pound of either, at half atmospheric pressure, contain more?
: : Thank you in advance for any light you can shed.
