Description

The Small Line Flowmeter, Engineered for Accuracy

The integral orifice meter run assembly represents a specialized and highly refined approach to differential pressure (DP) flow measurement, specifically designed to address the unique challenges of smaller line sizes. In pipes with a nominal diameter down to DN15 ($½$“), traditional DP flowmeters can suffer from significant measurement uncertainty. This is because minor geometric imperfections, such as surface roughness or weld seams, have a disproportionately large influence on the fluid dynamics and, consequently, the accuracy of the measurement. The integral orifice meter run assembly solves this problem by providing a standardized, pre-calibrated meter run that includes a minimum length of straight upstream and downstream pipe. This careful engineering ensures that the flow profile is fully developed and laminar before it reaches the orifice, thereby eliminating the additional uncertainties caused by installation effects. This complete, factory-calibrated system is delivered as a single unit, ready for immediate installation, and it provides a level of accuracy and reliability that is essential for critical process and allocation measurements of liquids, gases, and even complex fluids with suspended solids or gas entrainment.

 

Understanding the Principle of Precision

The operational heart of the integral orifice meter run assembly lies in the time-tested principle of differential pressure. When a fluid or gas passes through a constriction, such as the integral orifice plate, its velocity increases, leading to a measurable drop in pressure on the downstream side. The relationship between this differential pressure and the volumetric flow rate is a fundamental physical law. What sets this assembly apart is the meticulous control over the surrounding conditions. The standardized calibrated meter run assembly, designed in strict accordance with ISO 5167 or ISO/TR 15377, guarantees that the flow entering the orifice is predictable and stable. By eliminating the need for on-site pipe runs and supports, the assembly removes a major source of potential measurement error. The included DP transmitter, which is pre-assembled and pre-configured, precisely measures the pressure difference and translates it into an accurate flow reading. This highly controlled and pre-calibrated system ensures a level of measurement integrity that is simply unattainable with field-installed components, making it an ideal choice for high-accuracy applications.

 

Applications Across a Spectrum of Industries

The integral orifice meter run assembly’s precision and robust design make it an invaluable tool across a wide range of industries where small-line flow measurement is critical. In chemical and petrochemical plants, it’s used for precisely dosing chemical additives, monitoring reaction flows, and managing solvent usage. Its ability to handle a variety of media, including viscous fluids and those with solids, makes it perfect for these demanding environments. In the oil and gas industry, these assemblies are used for custody transfer applications and allocation measurement, where every drop and cubic foot counts. They are also crucial for monitoring fuel gas flows to burners and flares. In the food and beverage industry, they provide accurate measurement of ingredients in small lines, ensuring product consistency and quality control. Furthermore, their resilience to high temperatures and pressures makes them suitable for measuring steam and hot liquids in pharmaceutical manufacturing and power generation. The flexibility of the assembly, with various material and communication options, allows it to be tailored for virtually any small-line process application, ensuring safety and efficiency.

 

Advanced Design Features for Enhanced Performance

The integral orifice meter run assembly is packed with features that go beyond its core principle, providing enhanced performance and reliability. A significant advantage is the elimination of external impulse lines. This design choice not only simplifies installation but also drastically reduces the potential for leaks, which is a major safety and environmental concern in many industrial settings. The OPTIBAR DP transmitter is a key component, offering advanced 3-D linearisation that minimizes the need for costly and time-consuming recalibration in the field. This smart technology, combined with the pre-calibrated meter run, ensures sustained accuracy over time. The entire solution, from the orifice plate to the manifold and DP transmitter, is available from a single source. This simplifies the procurement process, ensuring compatibility and providing a comprehensive set of documentation, including sizing and engineering specifications, right from the start.

 

Unwavering Reliability in Extreme Conditions

Engineered to operate in the most challenging industrial environments, the integral orifice meter run assembly is a symbol of durability and reliability. It is built to withstand an impressive range of process temperatures, from a frigid −130∘C (−202∘F) up to a scorching +400∘C (+752∘F). This broad temperature range allows it to be used for everything from cryogenic applications to high-temperature steam measurement. The assembly is also designed to handle high line pressures up to $160$ bar ($2320$ psi). A variety of robust materials are available for the measuring tube, including austenitic stainless steel (1.4404/316L), carbon steel (A105), and various alloy steels, ensuring exceptional corrosion resistance and mechanical strength. For mission-critical applications, the assembly can be configured with redundancy options (1oo2, 2oo3), which provide a high level of safety and reliability. The device’s certification for SIL 2/3 safety applications further underscores its suitability for use in safety-instrumented systems where precise and reliable measurement is paramount.
