This Practice provides installation details and describes the minimum requirements for installing orifice plates in gas, liquid, steam, or condensing vapors service.
This Standard covers pressure-temperature
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 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...
SCOPE AND FIELD OF APPLICATION This Standard specifies the geometry and method of use (installation and flowing conditions) for orifice meters of 6 mm to 40 mm (¼ in. to 1½ in.) line size when they are inserted in a conduit running full. It also gives necessary information for...
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...
This part of 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 ISO 5167 also provides...
FOREWORD This report analyzes four flange tap equations and three corner tap equations for the discharge coefficient for orifice plates. All of the equations analyzed are functions of Beta Ratios, Reynolds Number, and Line Size, and all data points were evaluated against each of the...
INTRODUCTION Description As its name implies, an orifice meter utilizes an orifice for its basic component in the measurement of natural gas. The placing of an orifice in a pipe in which there is gas flow creates a pressure difference across the orifice. This pressure...
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 part of IS0 5167 specifies the geometry and method of use (installation and operating conditions) of orifice plates, nozzles and Venturi tubes when they are inserted in a conduit running full to determine the flow-rate of the fluid flowing in the conduit. It also gives...
SCOPE AND FIELD OF APPLICATION This International Standard specifies the geometry and method of use (installation and operating conditions) of orifice plates, nozzles and venturi tubes when they are inserted in a conduit running full, to determine the rate of the fluid flowing...
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....
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:...
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...
