Orifice plate with annular chambers
The version orifice plate with annular chambers comprises two support rings which are connected to the inside of the pipe over an annular chamber and an annular gap. Tapping sockets direct the differential pressure from the support rings to the differential pressure transmitter over shut-off fittings and differential pressure lines.
The orifice disk is inserted between the support rings together with a gasket.
Orifice plate with single tappings
In the version of the orifice plate with single tappings the orifice plate is a single unit. The inside of the tube is connected to the tapping sockets by two single tappings.
Both types of orifice plate are installed between two flanges in the pipeline.
