Manufacturing facility supporting differential pressure flow measurement components and precision machining

Flow Measurement Products & Precision Machining by Flowell

differential pressure flow measurement components, meter-run assemblies, and build-to-spec machining support for industrial piping systems.

Start Here: Flow Measurement Systems

Use these hubs to match the right primary element and accessories to your service conditions, allowable pressure loss, and documentation requirements. Each hub links you to the correct product pages and the most relevant calibration and accuracy resources.

Differential Pressure Flow Measurement
Overview hub for DP measurement fundamentals, selection guidance, and system-level decisions.
Orifice Plate Flow Meter Systems
When you need standards-based DP measurement with broad industry adoption and cost-effective primary elements.
Venturi Flow Meter Systems
A strong fit when lower permanent pressure loss and long-term stability matter.
Flow Meter Accuracy & Calibration
Calibration, accuracy factors, and field realities that impact measurement confidence.

What We Build

Flowell manufactures flow measurement components used across oil and gas, chemical processing, power generation, water and wastewater, and industrial facilities. From stocked items to build-to-spec projects, we focus on repeatable machining, fit-up consistency, and responsive quote support.

Engineering & Standards Alignment

Many DP measurement configurations and documentation practices align to industry standards and accepted engineering frameworks. For broader standards reference, visit ASME. If you need calculations, dimensional drawings, or documentation support for procurement, include that in your request.

Frequently Asked Questions

Where should I start to avoid choosing the wrong configuration?

Start with the system hubs: Differential Pressure Flow Measurement and then pick the right path: Orifice Plate Flow Meter Systems or Venturi Flow Meter Systems. For performance realities and maintenance, use Flow Meter Accuracy & Calibration.

What information do you need for sizing support?

Line size/ID, media, operating pressure and temperature, min/normal/max flow, and any limits on allowable pressure loss. Use Sizing Support to send details or Contact Us for quoting.

Do you support custom machining outside catalog configurations?

Yes. If you have non-standard dimensions, material requirements, or a specific fit-up, start with Custom Machine Work and include your documentation and inspection needs.

Do you ship outside your local region?

Yes. Flowell ships products nationwide and can support international orders depending on product type, documentation requirements, and lead time.
