From high-quality portable field to stand alone measurement instruments and system EXIMP offers you end to end solutions that will help you monitor, protect and control your critical processes and applications.
Whether your process is up, mid or downstream, and application demands for custody transfer meters or accurate measurement of liquid or gas, EXIMP understands that an integrated equipment and expertise solution can help give you a competitive advantage. We are the experts for dependable and accurate flow measurement systems and will work with you to analyze your unique requirements and provide answers to your technical and business related problems.

INTEGRATED DESIGN CAPABILITIES

Our group of specialized measurement engineers consciously make the right engineering decisions and thus help positively impact the project costs and design. We are adept at selecting the right metering technology, making right engineering decisions, anticipating operations and installation to design problems, which helps us avoid costly changes during execution.
The basic requirement of any flow metering package is selecting the right measuring principle. This in turn depends on the selection and sizing of the flowmeter, service fluid properties, system uncertainty, flow rates, system pressure drop etc.

• ORIFICE METER

METER TUBES

Available in two or three section designs with flow conditioning plates. The meter tube is the most critical component for accurate measurement. Meter Runs are fabricated from pipe that is selected for diameter, roundness and straightness. We offer the entire package.

FLOW CONDITIONING SYSTEM

The complete system includes a flow profile conditioning plate and a straight pipe run of ten-diameters upstream of the Sentinel meter body. The system requires the customer to provide a minimum of five-diameter straight pipe run both upstream and downstream of the installation. When used in a bidirectional flow application, the system includes an additional flow profile conditioning plate and ten-diameters of straight pipe run on the downstream side of the flowmeter.

ORIFICE FITTINGS

The Orifice Fitting is a high-quality, high-accuracy orifice fitting manufactured in a wide selection of sizes and materials. These units are built to meet or exceed ASME and ANSI specifications as well as to comply with the requirements of the latest editions of AGA-3, ISO-5167 and API-14.3. The fittings are available to meet the NACE MR-0175 specifications.

Orifice Plate Seal assemblies

The assemblies comply with the latest editions of AGA-3 and ISO- 5167. The seal assembly mounts securely on to the existing plate carrier with setscrews. it comprises of a stainless steel seal and retainer ring. Standard size O-Ring seals in a variety of compositions are incorporated. A solid seal is established both on the orifice plate and on the seal surfaces of the orifice fitting body. This unit simplifies orifice plate changing.
Stainless Steel internals are also available to meet extreme corrosive applications.
These fittings are designed and constructed to allow orifice plate replacement or inspection under pressure without interruption of flow in the line.

CONFORMANCE AND REPORTING

• All fittings come standard with a documentation package including hydro test, functional test, inner valve seal test, quality control inspection report and material test reports
