BS 1042-1-1.5:1997 Measurement of fluid flow in closed conduits. Pressure differential devices - Guide to the effect of departure from the conditions specified in BS EN ISO 5167-1

Withdrawn
This Section of BS 1042 provides guidance to assist in estimating the flowrate when using pressure differential devices constructed or operated outside the scope of BS EN ISO 5167-1. It should not be inferred that additional tolerances or corrections can necessarily compensate for the effects of deviating from the standard. The information is given, in the first place, to indicate the degree of care necessary in the manufacture, installation and maintenance of pressure differential devices by describing some of the effects of non-conformity to the requirements; and in the second place, to permit those users who may not be able to comply fully with the requirements to assess, however roughly, the magnitude and direction of the resulting error in flowrate. Each variation dealt with is treated as though it were the only one present. Where more than one is known to exist, there may be unpredictable interactions and care has to be taken when combining the assessment of these errors. If there is a significant number of errors, means of eliminating some of them must be considered. The variations included in this standard are by no means complete and relate largely to examples with orifice plates. There are, no doubt, many similar examples of installations not conforming to BS EN ISO 5167-1 for which no comparable data have been published. Such additional information from users, manufacturers and any others may be taken into account in future revisions of this Section of BS 1042.
