DIFFERENTIAL PRESSURE DEVICE
ORIFICE PLATES ^{WITHOUT CARRIER RINGS}
Tapping of differential pressure is done by this D and
D/2 tap orifice. Since orifice plate can be installed di-
rectly to flange of pipe, flow measurement by this orifice
plate can be performed more economically than by orifice
plates with rings, and it is generally suited for large diam-
eter pipes.
