A fully coded, one-piece flowmeter that combines the features and benefits of integral orifice metering with a 3- or 5- valve instrument manifold and the latest ABB DP and multivariable transmitters.
FPD220 is dual-chamber orifice fitting with double block and bleed (DBB) isolation, suitable for fiscal (custody transfer) applications. These fittings enable orifice plates to be safely inspected and / or replaced without removing the fitting itself from the pipeline.
The integral orifice is a flow element can be close -coupled with differential pressure transmitters to make a complete flow meter. It provides easy-to-install, low-cost measurement of the small flows found frequently in plant metering operations and research projects.
When high accuracy flow measurement of liquids, gases and steam is demanded from the primary flow element, an orifice flange assembly can be welded into a fabricated orifice meter run, incorporating the upstream and downstream pipe sections required by ISO5167-1:2003.
The FPD470F is a wedge meter with DP connections for flanged remote seals. The flow element consists of a body and wedge flow restriction. This restriction creates a differential pressure in proportion to the square of the volumetric flow rate.
