Measurement of fluid flow in closed conduits. Guidelines on the effects of flow pulsations on flow-measurement instruments1 Scope This document defines pulsating flow, compares it with steady flow, indicates how it can be detected, and describes the effects it has on orifice plates, nozzles or Venturi tubes, turbine and vortex flowmeters when these devices are being used to measure fluid flow in a pipe. These particular flowmeter types feature in this document because they are amongst those types most susceptible to pulsation effects. Methods for correcting the flowmeter

The object of this performance specification template is to provide a frame for the preparation of performance standards and/or product specifications on the performance of OA devices to be used in single channel applications

It complements the implementation of BS ISO 14065
