Content Description

This Standard specifies the geometric and method of use (installation and flowing conditions) for orifice meters of 6 mm to 40 mm (1/4 in. to 1 ½ in.) line size when they are inserted in a conduit running full. It also gives necessary information for calculating flow rate and its associated uncertainty. It applies only to differential pressure devices in which the flow remains subsonic throughout the measuring section, flow is steady or varies only slowly with time, and the fluid is considered single-phase. In addition, the uncertainties are given in the appropriate sections of this Standard for each of these devices within the pipe size and Reynolds number limits, which are specified. This Standard covers devices for which sufficient calibrations have been made to enable the specification of coherent systems of application and to enable calculations to be made within certain predictable limits of uncetainty. The devices introduced into the pipe are called primary devices. The term primary device also includes the pressure taps and the associated upstream and downstream piping. All other instruments or devices required for the measurement or transmission of the differential pressures are known as secondary elements, and in combination are referred to as the secondary devices. This Standard covers primary devices; the secondary devices will be mentioned only occasionally, as and when necessary for the proper operation of the primary device. The different primary devices covered in this Standard are (a) orifice plates used with corner pressure taps, (b) orifice plates used with flange pressure taps, (c) specially designed orifice meters with integral fittings.

About ASME

ASME is a not-for-profit membership organization that enables collaboration, knowledge sharing, career enrichment, and skills development across all engineering disciplines, toward a goal of helping the global engineering community develop solutions to benefit lives and livelihoods. Founded in 1880 by a small group of leading industrialists, ASME has grown through the decades to include more than 130,000 members in 158 countries. Thirty-thousand of these members are students.

From college students and early-career engineers to project managers, corporate executives, researchers and academic leaders, ASME's members are as diverse as the engineering community itself. ASME serves this wide-ranging technical community through quality programs in continuing education, training and professional development, codes and standards, research, conferences and publications, government relations and other forms of outreach.
