This Practice provides fabrication details and describes the minimum requirements for fabricating concentric or eccentric square edge orifice plates and the orifice meter run.
This Practice provides installation details and describes the minimum requirements for installing orifice plates in gas, liquid, steam, or condensing vapors service.
ESDU 81039 provides basic data for use in the calculation of pressure losses for incompressible flow (generally liquid flow) in ducts containing orifice plates, perforated plates and thick orifice plates or in the determination of a suitable geometry for a...
This part of SAE J968 specifies the flow measuring system, including the fixture, to be used for flow testing the single hole orifice plates used in an orifice plate type nozzle and holder assembly (described in SAE J968/1) which is intended for testing and setting...
This standard is intended to cover only orifice plates designed for bolting between flanges, with flat or raised face, whose bolting dimensions are in accordance with one of the following ASA standards: B16b2 B16.1 B16b B16.5-1957 PURPOSE The purpose of this Standard is to establish:...
This Technical Note discusses the studies conducted by ESDU for the CFD validation of the predictions for pressure loss, discharge coefficient and flow characteristics in square-edged orifice plates. These studies used the validation data from the literature reviewed in ESDU TN 07007....
ESDU 82009 presents pressure loss and discharge coefficient data for subsonic compressible flow of gases through single, or multiple, sharp-edged orifices in thin or thick plates for flow rates up to choking. The mechanics of compressible flow through orifices are discussed...
This Technical Note provides a review of the data in the literature for incompressible flow through orifice plates published prior to 2006. These data include measurements and numerical predictions of the flow field and pressure distribution over the orifice test pipe, pressure...
Geometry and method of use for conical entrance orifice plates, quarter circle orifice plates and eccentric orifices plates Also square-edged orifice plates and nozzles outside the scope of BS 1042:Section 1.1.
This document describes the geometry and method of use for conical-entrance orifice plates, quarter-circle orifice plates, eccentric orifice plates and Venturi tubes with 10,5° convergent angles. Recommendations are also given for square-edged...
ESDU CFD-BPG 11010 provides the Best Practice Guidelines recommended by ESDU for the CFD modelling of pressure loss, discharge coefficient and flow characteristics in square- and knife-edged orifice plates. These Guidelines are based on the extensive ESDU CFD validation studies...
Describes the geometry and methods of use of various types of orifice plates and nozzles outside the scope of ISO 5167-1.
This part of EN ISO 5167 specifies the geometry and method of use (installation and operating conditions) of orifice plates when they are inserted in a conduit running full to determine the flowrate of the fluid flowing in the conduit. This part of EN ISO 5167 also provides background...
