Flowell Corporation

Precision-Fabricated Meter Tubes for Reliable Measurement

At Flowell, we specialize in manufacturing Meter Tubes that deliver precise and consistent flow measurement in a wide variety of industrial applications. Our meter tubes are engineered to integrate seamlessly with primary flow devices, including orifice flanges, orifice fittings, turbine meters, and ultrasonic meters. Whether you’re measuring natural gas, other hydrocarbons, or industrial fluids, our meter tubes are built to ensure accuracy, compliance, and long-term performance.

Built to Industry Standards You Can Trust

Each Flowell meter tube is designed and fabricated to meet the rigorous standards of ASME B31.8, which governs gas transmission and distribution piping systems. This ensures that our products meet the durability, reliability, and safety requirements for use in critical systems. In addition to ASME, our meter tubes also comply with API 14.3 and ISO 5167, both of which define best practices for flow measurement using differential pressure devices like orifice plates.

By designing and testing our meter tubes according to these standards, we give our clients confidence in the accuracy of their flow readings, which is essential for regulatory compliance, billing purposes, and operational efficiency.

Premium Welding and Fabrication Quality

At the core of every Flowell meter tube is our commitment to craftsmanship and quality assurance. All welding is performed by individually certified welders who follow qualified welding procedures. These standards help us maintain consistency in fabrication and provide durable, leak-free welds that stand up to demanding operational environments.

We take pride in our ability to fabricate customized and standard meter tubes with exceptional precision. From simple single-run tubes to complex dual-run configurations, we deliver solutions that meet exact customer requirements with tight tolerances and high repeatability.

Thorough Inspection and Testing Options

To further ensure the quality of every meter tube, we provide a range of testing and inspection options tailored to your project requirements:

• Standard Hydrostatic Testing: Every Flowell meter tube comes with an optional one-hour hydrostatic test to confirm the integrity of the welds and pressure-containing components. This test helps to ensure that the assembly is free from leaks and suitable for pressurized operation.
• Radiographic Testing (RT): As an additional option, we offer radiography to inspect welds internally. This non-destructive test is particularly useful when absolute weld quality is mission-critical.
• Dye Penetrant Examination: As part of our standard quality control process, we perform dye penetrant examinations on all meter tubes. This surface-level inspection identifies cracks or defects that could otherwise be missed by visual inspection alone.
• Certified Micrometer Readings: We provide certified micrometer readings with every tube to support traceability and document measurement accuracy. This data is especially valuable for auditors or customers who need clear documentation for compliance purposes.

Customization to Fit Your Needs

Every measurement application is unique, and our meter tubes are built with flexibility in mind. Whether you need specific lengths, diameters, or flow straightening components, we can customize your order to match your exact specifications. Some common customization options include:

• Flow Conditioners or Straightening Vanes: We offer the option to include flow conditioners or straightening vanes to reduce swirl and turbulence before the flow reaches the measurement element. This improves accuracy and consistency, particularly in installations where straight pipe lengths are limited.
• End Connections: Whether you require flanged ends, butt welds, or threaded connections, we can fabricate meter tubes with the right type of connection to match your piping system.
• Meter Run Configurations: We provide both single-run and dual-run meter tubes, as well as bi-directional options when required. Our team can assist in determining the best configuration based on your application.
• Support Stands and Skids: To simplify field installation, we offer optional skids and support structures that are custom-fitted to your meter tube configuration.

Designed for Longevity and Performance

Our meter tubes are not only built for measurement accuracy—they’re also built to last. We use high-grade carbon steel or stainless-steel materials, depending on the application and media being measured. Each tube is treated and coated as needed to resist corrosion and wear over time, making them ideal for use in both onshore and offshore environments.

Our fabrication and inspection process ensures that the final product is robust, precise, and dependable. It delivers long-term value and reduces the need for costly rework or early replacement.

Seamless Integration with Flow Measurement Devices

Whether your application uses a traditional orifice flange or a modern ultrasonic or turbine meter, our meter tubes are designed to integrate cleanly with your measurement equipment. Our engineering team pays close attention to upstream and downstream pipe lengths, surface finishes, and alignment to ensure that the flow profile is optimized for each specific device.

We understand that accurate measurement is about more than just quality materials—it’s about understanding flow dynamics and designing accordingly. That’s why every tube we fabricate is made with careful consideration of meter manufacturer guidelines, industry standards, and field best practices.

Commitment to Customer Satisfaction

We understand the critical role that meter tubes play in your operations. Whether you’re overseeing a pipeline installation, an industrial upgrade, or a metering station for gas distribution, you can count on Flowell to deliver a product that meets your timeline, specification, and performance expectations.
