June 2005

Overview

Materials

This Product Specification sheet defines the requirements for the Conditioning Orifice Plate (COP). This Specification is also included for Electronic Pressure Instruments when integrated with the Conditioning Orifice Plate (COP) primary to form complete flowmeters.

Vendor Requirements

The manufacturer of the COP shall be certified to the international standard ISO 9001.

The vendor shall have the ability to pre-assemble the COP primary with a pressure instrument (transmitter), perform a leak-test and calibrate the unit before shipping.

The vendor shall have the ability to provide technical support for the COP primary element and the pressure instrument.

When a pressure instrument is supplied with the COP, each pressure instrument shall be individually tested for accuracy using calibration equipment traceable to NIST or an equivalent internationally recognized authority.

Instrument Specifications

The COP shall perform within ± 0.5% to ± 0.75% of discharge coefficient (dependant on conditioning orifice beta size) and the vendor shall make independent testing documentation available demonstrating this performance.

The COP shall have the ability to accommodate isolation valves and connections that are suitable for connecting a pressure instrument.

All line sizes serviced by the COP shall be able to accommodate a remote RTD.

Conditioning Orifice Plate

The COP shall consist of four symmetrical orifice holes to allow flow separation independent of flow rate, pressure or temperature. As a result, a flow coefficient (Cd) shall be maintained over a wide range of Reynolds numbers.

These products shall deliver accurate and repeatable results when installed downstream of a variety of flow disturbances, that normally cause measurement errors in the flow process.

The primary element shall be available in 316 Stainless Steel, 304L Stainless Steel, Monel® and Hastelloy® 276 material types.

The COP shall be available for use with industry standard flanges:

•ANSI B16.5 (FF, RF, RTJ)

•ANSI B16.36 Orifice Flange Unions (FF, RF, RTJ)

•DIN EN.1092 (FF, RF)

•DIN 19214 Orifice Flange Unions (FF, RF)

The COP material will be the same or equivalent to that of the Flange Unions.

Conditioning Orifice Type

The COP will be configured as either a Compact Orifice Plate design or as an Orifice Plate design. Both designs will have four symmetrical orifice holes with a specific beta size depending on the process application.

Compact Conditioning Orifice Plate

•Shall be of all-welded design

•Shall be capable of withstanding 1440 psig at 100°F (99 bar at 38°C)

•Shall be capable of installing between ANSI Flange Unions

•Shall have a centering mechanism for installation in center of pipe

•Shall be capable of direct mounting to the pressure instrument

Conditioning Orifice Plate

•Shall be of Paddle type or Universal Type

•Shall be capable of withstanding 6000 psig at 100°F (408 bar at 38°C)

•Shall be capable of installing between Orifice Flange Unions

Flowmeter Specifications

The vendor shall be able to supply the COP primary integrated with the pressure instrument to create a complete flowmeter.

•The vendor shall have the ability to provide a flowmeter for both volumetric and mass flow output.
