MeasureMasterDual Chamber Orifice Fitting
FMC Technologies Measure
Master is engineered and
manufactured to ensure complete
safety and superior measurement
accuracy, simplicity of operation
and economy. For maximum op-
erational stability and efficiency, its
design allows regular orifice plate
inspections without interrupting
the product flow. MeasureMaster
fully complies with the stringent
requirements of the latest editions
of AGA #3 / API 14.3 and
ISO 5167 measurement standard
specifications and tolerances and
is inspected and tested during
manufacturing and assembly to
ensure 100% compliance and
unmatched accuracy.
Safety, accuracy and ease of opera-
tion, key requirements for gas
measurement equipment, are
the basic elements built into
every MeasureMaster Dual
Chamber fitting.
Features and Benefits• Designed to allow inspection or replacement of the orifice plate
without interrupting the flow.
• Most parts can be replaced without removing the fitting from the line.
• Slip-lock design prevents cover plate blow-off in the event the line has not been depressurized.
• Designed to provide maximum safety to the operator during operation, service and inspection.
• Tested for positive plate sealing, pressure tap integrity, seal protrusion and eccentricity.
• Meets stringent requirements
The MeasureMaster’s unique “Dry Seal Valve” guarantees upper chamber isolation by way of a precision compressed o-ring seat valve for greaseless – and safe – operation and maintenance. The valve design provides superior sealing capabilities and substantial reduction in turning torque allowing easy operation even in large diameter fittings.
Advantages• Most seals are standard size o-rings for
immediate worldwide availability• Superior o-ring seals for cover bar
compared to composite gaskets • Rugged standard design clamping bar
bolts provide superior strength to prevent breakage
• Service access to internal parts does not require orifice fitting top section removal
• Simpler operation compared to other designs
• Proven safety record
Improvements• Non-lubricated design for minimal main-
tenance and enhanced operation:– Improved, non-lubricated internal
stem seals– Non-lubricated isolation valve– Reduced torque requirements to operate
isolation valve– Greaseless bearings minimize corrosion
on operating stems• Improved, top seal design for easier
operation and extended seal lifeIn addition to its design enhancements, every MeasureMaster Orifice Fitting and its components are thoroughly inspected and tested prior to customer shipment – 100% of the time.
Applications• Custody transfer to fiscal metering• Natural gas production and transmission• High pressure gas injection and storage
– Capable of bi-directional flow• Specialty products: CO2, ethylene, LPG,
light oils• Fuel gas (process plants, power genera-
tion, gas compression)
Design Codes• ASME B31.8 Gas Transmission and
Distribution Piping• NACE MR-01-75 – standard orifice
fitting design compliance for sour gas applications. Stainless steel and other alloys are available as an option
Also in compliance with: ASME B31.1 Power Piping; ASME B31.3 Process Piping. PED available upon request.
Complete Product LineOffering products and services necessary for a complete gas measurement solution is the primary objective of FMC Technologies. To provide this solution to our customers, MeasureMaster is available in a wide range of sizes and pressure ratings for applica-tion versatility (Refer to Bulletin SSOR001). Standard sizes range from 2”-24”, ANSI 150 - 600 pressure class. Other sizes available on request.As a compliment to the fittings themselves, FMC Technologies Measurement Solu-tions offers orifice plates, meter tubes and replacement parts for a total orifice fitting package. In addition, our flow nozzles and venturi tube product lines are available when application requirements specify a device capable of measuring demand-ing flow streams or in applications where flange connections are not desirable or acceptable.Choosing and applying the right gas measurement solutions is possible with the broad product range offered by FMC Technologies Measurement Solutions.
Low Maintenance Costs and Long Service LifeCost efficiency and reduced downtime increase the output value of any mea-surement application. With only seven
operating steps, four moving parts and five recommended spare parts, MeasureMaster is designed to keep maintenance costs to a minimum, while providing reliable service.Several key features of its design include:• Seals utilize standard o-rings for easy
and inexpensive replacement• Greaseless bearings eliminate the need
for operating shaft lubrication and pro-tect mating parts from corrosion
• Carrier and elevator screw combine rug-gedness and jam-free operation
Simple operation, few moving parts and technician-friendly design translate to low costs and high operating efficiency.
Worldwide Support and ServiceFMC Measurement Solutions’ highly specialized and experienced gas measure-ment engineers and support personnel are available anywhere in the world to provide application recommendations, custom design capabilities, assistance with instal-lation, operation, field service and other support services.
Highest Measurement StandardsThe MeasureMaster is in compliance with the latest editions of:• API 14.3, Manual of Petroleum Measurement
Standards, Chapter 14 Natural Gas Fluids Measurement, Section 3 Concentric, Square-edged Orifice Meters (AGA Report No. 3, American Gas Association)
• GPA 8185-90, Part 2, Gas Processors Association
