Fuji EDS6-50I Differential pressure device orifice plate with carrier ring Datasheet

FFI SYSTEM
DIFFERENTIAL PRESSURE DEVICE
ORIFICE PLATE WITH CARRIER RINGS
DATA SHEET
FVA
This orifice plate is widely used for measuring liquid,
steam, and gas in low or medium pressure, lines. Tapping
of differential pressure is done by comer tap method with
differential pressure tapping rings having CARRIER RINGS.
One set is composed of differential pressure tapping rings,
an orifice plate, and a gasket. CARRIER RINGS are installed
to average the differential pressure inside the rings.
