These may be located in various positions, depending on the application (e.g., corner, D and D/2, or flange tappings), and reference should be made to BS Part 1 for correct rate is determined from Equation ().

An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice: 85–86 but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.

A little downstream of the orifice the flow reaches C d {\displaystyle C_{d}}: = coefficient of. Flow measurement by square-edged orifice plate using corner tappings. Oxford, New York, Pergamon Press [] (DLC) (OCoLC) Material Type: Document, Internet resource: Document Type: Internet Resource, Computer File: All Authors / Contributors: W J Clark.

Here, pressure taps are located 1 pipe diameter upstream and ½ diameter downstream from the orifice plate (see figure ). This arrangement is best from a practical standpoint because the downstream pressure tap is located at about the mean position of the vena contracta, and the upstream tap is sufficiently far upstream to be unaffected by distortion of the flow in the immediate vicinity.

Orifice plates are most commonly used primary elements for flow measurement in pipelines based on the principle of measurement of ‘differential pressure’ created when an obstruction is placed in the fluid flow, due to increase in fluid velocity.

Orifice Plates cover a wide range of. Fundamentals of Orifice Meter Measurement This white paper provides an overview of orifice meter technology, its advantages and general installation recommendations, as well as describes basic gas flow laws and the variables of orifice meter flow equations.

The concentric orifice plate flow meter has a sharp (square-edged) concentric bore Flow measurement by square-edged orifice plate using corner tappings book provides an almost pure line contact between the plate and the fluid, with negligible friction drag at the boundary.

The beta (or diameter) ratios of concentric orifice plates range from to The maximum velocity and minimum static pressure occurs. - the type of orifice plate (Square, Restriction etc.) Letter height approx.

4 mm; Welding of tab Tab may be integral with orifice plate up to and including 7 mm plate thickness. In other cases full penetration joint to be applied. Finish of plate The upstream and downstream faces of the orifice plate to a diameter equal to D3 shall have a. In the case of an orifice plate with no downstream pipeline, ISO/TR implied that an orifice plate discharging into a large space from a pipe of finite bore will have the same discharge coefficient using corner tappings as an orifice plate installed with a downstream pipe of the same diameter as the upstream by: 3.

Orifice Bore: In accordance with ISO, BS, ASME MFC 3M, AGA Tab Plate: In the same material as plate & is welded to orifice plate. Tab plate integral to the Orifice plate (i.e. without welding) can also be offered as a special case.

Orifice plate meter flow measurement. An orifice meter is a circular piece of metal plate placed between flanges in a pipe.

In it is a square-edged round hole machined to pipe diameter in size. Pressure tapping points are placed either side of the plate at specified distances.
