DIFFERENTIAL PRESSURE DEVICE
ORIFICE PLATES
WITH FLANGE TAPPINGS
DATA SHEET
FVC
Tapping of differential pressure is done by orifice plates
with flange taps. So that differential pressure can be tapped
from points located 25.4mm away from both sides of the
orifice plate, the pressure tapping pipe is equipped to the
flange section.
It is used to measure liquid, steam, gas, etc. The orifice
plate is designed for easy removal.
