ABB Australia have announced the launch of ABB Australia's OriMaster Compact Orifice DP flowmeter. The latest in ABB Australia's new FlowMaster range, the OriMaster 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 Compact Orifice DP flowmeter 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%.
Featuring an integrated ABB DP transmitter and manifold design, OriMaster Compact Orifice DP flowmeter offers a number of key benefits. Its short integral impulse paths simplify installation, and by eliminating up to 80% of the potential leak points, greatly reduces both fugitive emissions (at threaded connections and compression fittings) and also the metering errors caused by such leakage.
The OriMaster Compact Orifice DP flowmeter's all-in-one design also offers enhanced accuracy and a faster speed of response, with no problems caused by issues such as long or blocked impulse lines, or impaired signals due to condensation in gas system impulse lines or gas bubbles in liquid lines.
Installing the OriMaster Compact Orifice DP flowmeter is simplified by its wafer design orifice carrier assembly, enabling it to be fitted into an existing space between standard pipe flanges with minimal disruption to the surrounding pipe work. This makes it ideal for Maintenance, Repair and Overhaul (MRO) applications, by enabling fast and simple replacement with no cutting or welding required.
Incorrect centralisation of orifice devices can cause additional metering errors of 3%. To eliminate such errors, every OriMaster Compact Orifice DP flowmeter comes complete with a centralisation tool, ensuring that the meter is correctly positioned in the pipeline within common flange specifications.
The selection process is simplified by having just two orifice bores for each pipe size and versatility is ensured as the OriMaster Compact Orifice DP flowmeter is supplied in two versions – OriMaster V and OriMaster M. The OriMaster V is 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 analogue output.
The OriMaster M provides measurement directly in mass or corrected volume units. It uses ABB Australia's 267CS multivariable transmitter to measure differential pressure, temperature and pressure, providing an optional display and analogue output. In addition to its stainless steel 316L body and alloy transmitter case, which is optionally available in 316 stainless steel, the OriMaster M can be supplied complete with an optional PT100 temperature sensing assembly mounted within the flow sensor, offering both simplified and cost-effective installation.
Both the OriMaster V and OriMaster M have HART communications and the OriMaster M has the additional options of Profibus PA, Foundation Fieldbus or Modbus communications.
To simplify the selection process, ABB Australia supply a free sizing, selection and coding software tool to help users to quickly turn their application into the best configuration of OriMaster Compact Orifice DP flowmeter for their needs. The software is available online or on CD.
