WebBeta Ratio is the ratio between the line inner diameter to bore size of the orifice. The flow coefficient is found to be stable between beta ratio of 0.2 to 0.7 below which the uncertainty in flow measurement increases. An orifice plate beta ratio of 0.6 means that the orifice plate bore diameter is 60% of the pipe internal diameter. WebThe table given below gives the discharge of air through an orifice in cu. ft. of free Air per minute at atmospheric Pressure of 14.7 psia, and 70 °F Based on 100% coefficient of flow. For well-rounded entrance multiply values by 0.97.

WebFinish of plate. The upstream and downstream faces of the orifice plate to a diameter equal to D3 shall have a surface roughness Ra ≤ 0.8 µm ASME B46.1. The remaining annular part (between D4 & D3) of upstream and downstream faces shall have a surface roughness Ra between 3.2 and 3.6 µm ASME B46.1. WebThe downstream side of the orifice plate is bevelled if the plate is relatively thick (1/8” or 1” or more). This bevelling helps to minimize contact with the fluid stream. Bevelled orifice plates are obviously uni-directional, and must be installed with the paddle text facing upstream while the bevelled end faces downstream.
