Established in 1987, F. Master is a manufacturer specializing in DP Flow Meters, Orifice Fittings, and Orifice Meter Tubes.

F. Master was the first Brazilian company to develop and manufacture Orifice Fittings for gas measurement in South America. Our Orifice Meter Tubes are currently working in several offshore production facilities.

We are an ISO 9001: 2015 certified company.


  • Dual Chamber Orifice Fitting
    Allows for accurate flow measurements, orifice plate inspection and changing without depressurizing the flow line. As a proven technology, F. Master Orifice Fittings have been supplied to offshore production facilities for over 16 years....

  • Dual Chamber Orifice Fittings have an extra chamber into which the orifice plate is first withdrawn; this chamber is then isolated from the pipeline. This means that the flow in the pipeline does not necessarily have to be stopped to enable removal and refitting of the orifice plate.


    • Field-repairable, reducing downtime and costs associated with shipping to a repair site
    • Ensures fast and safe plate replacement
    • Greaseless design. Delivers clean, positive isolation between upper and lower chambers
    • All F. Master Orifice Fittings are hydrostatically tested to 1.5 times operating pressure
    • According to ASME B16.5, ASME B31.4, ASME B31.8 Standards

    Line Size: 2 to 24"

    Discharge Coefficient Uncertainty: In accordance with AGA 3/API 14.3

    Max. Operating Pressure: ANSI 2500

    Materials: Carbon Steel, Stainless Steel, Duplex. Others on request.

  • FlowCone
    F. Master's Flow-Cone flow meter is an advanced differential pressure instrument. A key feature of this device is its ability to fit into small spaces while offering high levels of accuracy and repeatability....

  • Designed for mild to harsh operating environments, and for a variety of fluids such as liquid, steam or gas where accuracy, low maintenance and cost are important, this advanced flow meter stands out from other flow technologies.

    According to ISO 5167 Standard.

    Line Size: 0.5 to 120" or larger

    Accuracy: ±0.5% of rate (certain fluids and Reynolds number applications require specific calibrations to achieve this value)

    Repeatability: ±0.1%

    Materials: Carbon Steel, 304/316 Stainless Steel, Duplex. Others on request.

  • Orifice Meter Tube
    F. Master manufactures custom meter tubes or meter runs for all of our orifice fitting models, orifice flanges and a variety of other metering applications....

  • Built by qualified welders with decades of experience, F. Master meter tubes adhere to the hightest quality standards to ensure internal roundness, a smooth, even surface finish, and precise alignment for enhanced long-term measurement performance.


    • Highly reliable and field-repairable
    • Ensures fast and safe plate replacement
    • Meet application and/or installation needs with weld fitting and ends that can be beveled, flanged or reduced
    • Ensure performance in accordance with ASME with optional hydrostatic testing to 1.5 times operating pressure

    Accuracy: In accordance with AGA 3/API 14.3, ISO 5167

    Max. Operating Pressure: ANSI 2500

    Materials: Carbon Steel, 304/316 Stainless Steel, Duplex. Others on request.
