Compact orifice DP flowmeters

The OriMaster compact orifice DP flowmeter is a one-piece flowmeter that comes fully factory configured and pressure tested, solving many of the problems associated with sizing, selection, installation and operation of conventional orifice plate installations.

Suitable for clean liquids, gases and steam applications in line sizes from 1 to 8" (DN25 to DN200) and at pressures up to 100 bar, the OriMaster combines all the major components needed for an orifice plate installation in one assembly. This eliminates the need for users to source and install a separate manifold, transmitter and impulse piping, typically cutting the cost of installation and commissioning by up to 50%. It can be fitted into an existing space between standard pipe flanges with minimal disruption to the surrounding pipework.

Due to the integrated design, OriMaster eliminates up to 80% of potential leak points, greatly reducing both fugitive emissions (at threaded connections and compression fittings) and also the metering errors caused by such leakage.

There are two orifice bores for each pipe size and the OriMaster is supplied in two versions — OriMaster V and OriMaster M. OriMaster V is a designed for general-purpose volume measurement, featuring a stainless steel transmitter housing and meter body. It provides an optional flow rate and total display as well as an analog output.

OriMaster M provides measurement directly in mass or corrected volume units. It uses ABB’s 267CS multivariable transmitter to measure differential pressure, temperature and pressure.

Both the OriMaster V and OriMaster M have HART communications and the OriMaster M has support for Profibus PA, Foundation Fieldbus or Modbus.
