Orifice meters measure flow rates using differential pressure created when a fluid passes through an orifice plate. The flow calculations use a form of the Bernoulli equation with an empirical discharge coefficient. Orifice flow meter calibration helps reduce uncertainty in the discharge coefficient from 0.5% to 0.25%. Orifice meters are normally built to specification from standards such as API 14.3, AGA 3 and ISO 5167. Southwest Research Institute performs flow calibrations to lower uncertainty by matching the Reynolds number to the final application. Improved flow measurement improves accuracy for computing plant efficiency, system balances and end-user consumption. ![]() Orifice Plate Calibration & Flow Meter Services. Flow calibration of an orifice flange fitting and plate over the application Reynolds number range. Flow calibrations and tests at SwRI typically require one day for setup and checkout and half a day for testing. Clients can witness tests in person or monitor remotely. Constants for virtually every model of Orifice Plate, Nozzle, Venturi, Multi-Port. Averaging (MPA), Taylor Wedge, Veris Verabar and the ability to enter the flow coefficient. Only The FLOW CONSULTANT software contains the new equation. The orifice, nozzle and venturi flow rate meters use the Bernoulli Equation to calculate fluid flow rate using pressure difference through obstructions in the flow. Sponsored Links. In a flow metering device based on the Bernoulli Equation the downstream pressure after an obstruction will be lower than the upstream pressure before. Reports can be generated that reference either API 14.3/AGA-3, ASME PTC 19.5 or any other commonly used orifice meter standard. ISO 5167 Differential Flow Meter Services In addition to orifice plates and meters, we calibrate and test other ISO 5167 differential flow meters: • Cone meters • Averaging pitot meters, anemometers and other velocity flow meters • Subsonic venturis (ASME MFC-7M and ISO 9300) • Wedge flow meters Orifice Flow Meter Troubleshooting & Research SwRI has been a leader in orifice meter diagnostics for many years as evidenced by the development of the patented. Pulsation detection and assessment is just one of the services that we can provide to improve your measurement.

SwRI can provide field audits of meter stations that include orifice meters and suggest operational and configuration changes to improve your measurement. Many improvements to the orifice meter standards were verified by testing at SwRI's Metering Research Facility. To learn how SwRI has is helping to advance technology for orifice flow meters and other flow measurement systems. Flow Measurement & Metering Research • • • • Or call Terry Grimley at. Orifice Plate Calculation and Design One of the key challenges when dealing with flow measurement using differential pressure meters is the design of the primary flow element such as an orifice plate, flow nozzle, venturi or other differential producer. The design of an orifice plate or any other primary device starts with the accumulation of several data items. These data points are then used to design physical dimensions of the orifice plate including the outer diameter, the plate thickness, the handle requirements, and the orifice bore. Process data are used in a calculation iteration to develop the orifice bore, and once the physical dimensions of the orifice are decided, this information is then used to complete the overall flow calculation. Worksheets are often utilized in order to accumulate the needed data for the flow calculation.

A sample process data worksheet is included below: Triad Measurement & Equipment, Inc. The process of designing and manufacturing primary flow elements such as orifice plates and orifice plate meters involves a high level of accuracy not only in the manufacturing process, but also in the data accumulation and calculation process. Many information sources regarding flow calculations provide simplified versions of the detailed flow calculations. These should not be used for detailed design of orifice plates or any other differential pressure producer such as flow nozzles or venturi because they do not consider the vast number of correction factors and detailed fluid properties that are needed to ensure the most accurate meter possible.
