Product Description

Product Description

The orifice plate flow meter is a type of differential pressure flow meter that is commonly used in clean liquid, gas, and stream mass flow measurement. It is available for all pipe sizes, and if the pressure loss it requires is free, it is very cost-effective for measuring fluid flows in larger pipes (over 6" diameter). The orifice plate is also approved by many standards organizations for the custody transfer of liquids and gases.

The orifice flow equations - which make use of the Bernoulli Equation - that are used today still differ from one another, although the various standards organizations are working to adopt a single, universally accepted orifice flow equation. Orifice sizing programs usually allow the user to select the flow equation desired from among several.
The orifice plate can be made of any material, although stainless steel is the most common. The thickness of the plate used (1/8 - 1/2") is a function of the line size, the process temperature, the pressure, and the differential pressure. The traditional orifice is a thin circular plate (with a tab for handling and for data), inserted into the pipeline between the two flanges of an orifice union. This method of installation is cost-effective, but it calls for a process shutdown whenever the plate is removed for maintenance or inspection. In contrast, an orifice fitting allows the orifice to be removed from the process without depressurizing the line and shutting down flow. In such fittings, the universal orifice plate, a circular plate with no tab, is used.

Features of Annular Orifice Plate:

Measuring mediu

1. flow of general fluids; 2. fluids containing various impurities (such as dust, suspension, precipitation, etc.) 3. various coal gas hot wind, flue gas, natural gas, cooling water and so on.

Although it is a simple device, the orifice plate is, in principle, a precision instrument. Under ideal conditions, the inaccuracy of an orifice plate can be in the range of 0.75-1.5% AR. Orifice plates are, however, quite sensitive to a variety of error-inducing conditions. Precision in the bore calculations, the quality of the installation, and the condition of the plate itself determine total performance. Installation factors include tap location and condition, condition of the process pipe, adequacy of straight pipe runs, gasket interference, misalignment of pipe and orifice bores, and lead line design. Other adverse conditions include the dulling of the sharp edge or nicks caused by corrosion or erosion, warpage of the plate due to waterhammer and dirt, and grease or secondary phase deposits on either orifice surface. Any of the above conditions can change the orifice discharge coefficient by as much as 10%. In combination, these problems can be even more worrisome and the net effect unpredictable. Therefore, under average operating conditions, a typical orifice installation can be expected to have an overall inaccuracy in the range of 2 to 5% AR.

The typical custody-transfer grade orifice meter is more accurate because it can be calibrated in a testing laboratory and is provided with honed pipe sections, flow straighteners, senior orifice fittings, and temperature-controlled enclosures.

• When to measure saturated steam superheated steam, the accumulation of condensate formed by stopping steam can be avoided , and when supplying steam again, it can quickly enter the accurate measurement.
• There is a straight measuring tube in the instrument body, when installed on-site, there is hardly no affected to the instrument measurement by the installation errors (such as off-center, sealing gasket into the pipeline).
• Using the "pressure balancing ring" structure, when the length of the straight pipe section is not long enough, it can still be accurately measured. For example: in the downstream of a 90°elbow, it will be available where is a 2D length before the flowmeter; in the downstream of a 30° elbow, there is a 0.5D length before the flowmeter is available either.
• Adopting the "welding method" connection, suitable for high temperature and high pressure fluids (such as superheated steam), low cost, reliable work, stable performance.
• The use of "jacket insulation" structure, suitable for easily crystallized, easily vaporized and other need to be warmed or cooled fluids (such as liquid ammonia, some chemical products, etc.).
