ABB has released two online calculators showing how its Orimaster single-piece orifice flowmeter can help plant operators save on costs.

A conventional orifice flowmeter installation can be comprised of over 25 separate components, each presenting one or more potential leakage paths.

In comparison, ABB’s Orimaster features an integrated ABB DP transmitter and manifold design.

By eliminating up to 80 per cent of the potential leak points, it reduces fugitive emissions and metering errors caused by leakage.

The online calculators enable users to select a choice of pipe diameter sizes and set the number of orifice flowmeter installations at their plant.

The calculators then compare a conventional orifice hook-up, half-inch schedule 80-impulse pipe installation against the Orimaster to calculate the reduction in the number of leakage paths and the overall cost saving.

The Orimaster comes fully factory configured and pressure tested and is suitable for clean liquids, gases and steam applications in line sizes from 1 to 8in (DN25 to DN200) and at pressures up to 100-bar, the Orimaster combines the major components for orifice-plate installation in one assembly.

This eliminates the need for users to design, source and install a separate manifold, transmitter and impulse piping, typically cutting the cost of installation and commissioning by up to 40 per cent.

The Orimaster all-in-one design 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 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 pipework.
