ABB-Orifice carrier assembly with integral manifold FPD175
Overview
The ABB orifice carrier assembly is a convenient alternative to simple orifice plates, combining an orifice plate mounted in a carrier with the correct tapping points already fitted. This range, including the FPD175, provides a complete primary element for differential pressure flow measurement.
Part of the ABB orifice carrier range, the assembly combines the convenience of an orifice carrier with an integral, welded 3- or 5-valve manifold and an optional integral temperature element, reducing installation cost and leak paths.
Engineering & Design
The assembly supports options to reduce pipe straight runs with a multi-hole balanced orifice plate, which significantly improves measurement uncertainty and reduces head loss. A choice of 0.4 or 0.65 beta ratio ensures ease of configuration for the application.
Enhanced user flexibility is provided by direct mounting of a DP or multivariable transmitter to create a one-piece flowmeter, or remote transmitter mounting where direct mounting is not practicable. A centralising tool is supplied as standard, ensuring accurate centralisation of the meter in the pipeline, and optional removable orifice plates provide low-cost maintenance solutions for changes in process data or element wear.

Flow measurement accuracy starts with the primary element, and the ABB orifice carrier assembly provides it, which is why Seven Star LLC supplies the ABB FPD175 orifice carrier assembly for flow metering projects.
The ABB FPD175 orifice carrier assembly keeps the plate centred in the line.
The FPD175 carrier is available with the standard and the high pressure ratings and the material of the carrier is selected for the process fluid. The manifold isolates the transmitter for the zero check and the venting of the impulse lines during the operation. The assembly is supplied with the gaskets and the bolts for the flange installation, and the orifice plate is changed for the new flow range with the carrier in place.
The FPD175 assembly is used with the orifice plates of the primary elements and the carrier size is selected to match the meter run of the piping. The installation is verified with the pressure test after the flange tightening and the manifold valves are operated for the zero check. The spare gaskets and the bolts are supplied with the assembly.
The carrier assembly is matched to the meter run of the loop and the spare kit includes the gasket and the bolts for the flange re-assembly.
Why Seven Star LLC
Seven Star LLC supplies the ABB FPD175 orifice carrier assembly for flow measurement projects across the Gulf, with verified specifications and technical support. Our team assists with beta ratio selection, manifold configuration, and transmitter matching.
We support oil and gas, chemical, and process industries with reliable B2B supply of primary flow elements throughout the GCC.
Because the correct beta ratio and carrier material depend on the specific process fluid, pipe schedule, and expected flow range, we verify these details against your piping isometrics before an order is confirmed, rather than defaulting to a standard configuration that may not deliver the measurement uncertainty your application actually requires. We also confirm whether a 3-valve or 5-valve manifold suits your maintenance philosophy, since a 5-valve configuration supports safer in-service zero checks on higher-pressure applications where isolating the transmitter without a full process shutdown matters.
Metering Performance
The integral manifold and tapping arrangement reduce the number of potential leak points compared to separately mounted components, and the multi-hole balanced orifice option improves uncertainty and reduces head loss where straight run is limited. The 0.4 or 0.65 beta ratio options cover the common flow ranges.
Direct transmitter mounting creates a compact one-piece flowmeter, while the removable orifice plate option supports low-cost element replacement when process conditions change.
Planning for Long-Term Flow Measurement Accuracy
Orifice plate wear and process changes over years of service can quietly degrade measurement accuracy even when a flow reading still looks reasonable on a control room display, so we help customers plan periodic orifice plate inspection and replacement into their maintenance calendar rather than treating the primary element as a fit-and-forget component. The FPD175’s removable orifice plate design supports this directly, letting a plate be swapped for a new flow range or a fresh, unworn edge without disturbing the carrier body or the surrounding piping.
For projects specifying multiple orifice carrier assemblies across a facility, we help confirm a consistent beta ratio and manifold configuration approach where appropriate, simplifying future spares stocking and giving instrumentation technicians a familiar configuration to work with across different measurement points. Where a plant is upgrading older, separately-mounted orifice plate installations to the integrated carrier format, we are glad to review the existing piping and instrumentation before recommending a transition plan.
