QUALIFICATION OF A FLOW CONDTIONING DEVICE ACCORDING TO THE NEW API 14.3 PROCEDURE

Klaus Zanker, Dale Goodson
Abstract:
The new AGA 3/API 14.3 standard on concentric square edged orifice meters suggests that, if installation effects can be shown to be less than about 0.23 %, there is no need to apply any additional uncertainty to that of the basic discharge coefficient. This suggestion has revived interest in flow conditioners that can assure this performance without the need for long straight upstream lengths of pipe.
A feature of the new standard is that it specifies performance acceptance tests for evaluating other flow conditioners, which were not included in the previous versions of the document. In this paper we will review this procedure and show results for a device that has been qualified in this manner.
