Measurement of fluid flow by means of pressure differential devices. Guidelines on the effect of departure from the specifications and operating conditions given in ISO 5167 Ingestion-build-82396 Water supply authorities1 Scope This Technical Report provides guidance on estimating the flowrate when using pressure differential devices constructed or operated outside the scope of ISO 5167. Additional tolerances or corrections cannot necessarily compensate for the effects of deviating from ISO 5167 (all parts). The information is given, in the first place, to indicate the degree of care necessary in the manufacture, installation and maintenance of pressure differential
