Universal Orifice Plates
Flowell manufactures universal orifice plates for differential pressure flow measurement in gas, liquid, and steam service. These precision-machined plates are a practical choice when you need repeatable performance, dependable fit-up, and a well-established primary flow element that works with a broad range of industrial installations. If you are comparing complete assemblies instead of a stand-alone plate, review our orifice plate flow meter systems page. For broader technical reading and application guidance, you can also visit orifice plates.
Plate selection should be driven by actual operating conditions, not just line size. Bore design, material, edge condition, pressure class, media, and installation geometry all influence long-term performance. If your team is already working with process data, you can move directly to sizing support or contact us for help with an application-specific recommendation.
Application details that speed up quoting
A better recommendation usually starts with line size, media, operating pressure, temperature range, expected flow range, and allowable pressure drop. If you already have those details, Flowell can move faster on the right plate configuration.

- Minimum, normal, and maximum flow
- Fluid type and operating conditions
- Material and pressure class requirements
- Existing holder, flange, or meter run details
Universal orifice plates product overview
Universal orifice plates remain one of the most widely used primary elements in differential pressure measurement because they combine straightforward construction with proven measurement methodology. In the right service, they offer a practical balance of cost, repeatability, and maintainability. They are often selected for installations where teams want a familiar and serviceable solution that fits established engineering standards and plant practices.
If you are evaluating the surrounding assembly, mounting arrangement, or support hardware, Flowell also offers related components such as orifice flange unions, RTJ plate holders, meter tubes, and straightening vanes. You can also browse more categories through flow measurement products.
For users comparing measurement approaches rather than buying a replacement plate, the best next read is usually orifice plates or orifice plate flow meter systems, depending on how far along the project is.
Why engineers specify universal orifice plates
Simple, proven measurement method
Universal orifice plates support a well-known differential pressure approach that is broadly accepted across industrial flow measurement work.
Practical replacement and maintenance path
In many installations, the plate can be inspected, replaced, or matched to an existing assembly more easily than more complex metering technologies.
Broad service flexibility
These plates are commonly applied in liquid, gas, and steam service where the process conditions and installation geometry support reliable readings.
Universal orifice plates specifications and options
Exact dimensions and configuration details should always be tied to the application, but most selection discussions come down to a common set of specifications. These are the details that most often affect fit, repeatability, and suitability in service.
| Specification Area | What to Review | Why It Matters |
|---|---|---|
| Plate Type | Universal-style plate matched to holder or flange arrangement | Confirms the plate will integrate correctly with the intended installation hardware |
| Bore Configuration | Bore sizing based on flow range, fluid properties, and pressure drop limits | Directly affects measurement performance and usable operating range |
| Material | Stainless steel, carbon steel, and other alloys by service requirement | Supports corrosion resistance, temperature limits, and mechanical durability |
| Line Data | Pipe size, schedule, and internal diameter | Required to match the plate to actual installation geometry |
| Operating Conditions | Pressure, temperature, media, and expected flow profile | Helps determine whether the plate is the right fit for the application |
| Standards Considerations | Installation and calculation practices commonly referenced in industry | Supports consistent design review and more dependable field performance |
Universal orifice plates material and sizing considerations
Material and bore decisions should never be guessed. Corrosive service, elevated temperature, abrasive media, and pressure limitations all change what makes sense. If you are reviewing plate performance in a broader metering context, our differential pressure flow measurement page adds useful context, while the future-facing technical overview at orifice plates will serve users who need more education before submitting a quote request.
Common applications for universal orifice plates
Process and utility service
- Oil and gas operations
- Chemical processing lines
- Water and wastewater systems
- Power generation applications
- Steam and utility service
Typical reasons for selection
- Need for a proven differential pressure primary element
- Compatibility with existing meter runs or holder arrangements
- Preference for a practical replacement component
- Need for a machined plate matched to service conditions
- Project requirements tied to established industry practices
Not every application should default to an orifice plate. In services where permanent pressure loss is a larger concern, a different device may deserve review. That is one reason Flowell also covers alternatives such as venturi flow meter systems and product categories like flow nozzles.

Technical reference for universal orifice plates
For general industry background on differential pressure flow devices and installation methodology, ISO provides a widely recognized reference through ISO 5167. That external reference is useful for engineering context, but final product selection should still be tied to the actual service details, dimensions, and hardware arrangement involved in the job.
Universal Orifice Plates FAQs
What are universal orifice plates used for?
Universal orifice plates are used as primary elements in differential pressure flow measurement for gas, liquid, and steam applications where a proven and widely accepted measurement approach is required.
How do universal orifice plates differ from paddle-type orifice plates?
Paddle-type orifice plates are often chosen when handling and maintenance access play a bigger role, while universal orifice plates are commonly selected for broader general-purpose installations and established holder or flange arrangements.
Can Flowell help match a replacement plate to an existing setup?
Yes. Flowell can review dimensions, service data, and installation details to help identify a practical replacement path for an existing assembly.
What information is needed to quote universal orifice plates?
The most useful starting information includes line size, schedule, media, operating pressure and temperature, expected flow range, allowable pressure drop, and any existing holder or flange details.
