API MPMS CH 14.3.1, 4th Edition: Concentric, Square-Edged Orifice Meters, Part 1—General Equations and Uncertaint

CDN $395.00

This publication was last reviewed and confirmed in 2017.

Concentric, Square-Edged Orifice Meters, Part 1—General Equations and Uncertaint

SKU: 3757bf0ca2dd Category:

Description

Provides a single reference for engineering equations, uncertainty estimations, construction and installation requirements, and standardized implementation recommendations for the calculation of flow rate through concentric, square-edged, flange-tapped orifice meters. Both U.S. customary (USC), and international system of units (SI) units are included. The mass flow rate and base (or standard) volumetric flow rate equations are discussed, along with the terms required for solution of the flow equation. The empirical equations for the coefficient of discharge and expansion factor are also presented. This revision includes a change to the empirical expansion factor calculation for flange-tapped orifice meters.
