Abstract

Installation effects can not be exhaustively analysed due to the wide variety of plant configurations. On the other hand installation effects are one of the most important causes of flow meters inaccuracy. In the present paper the authors analyse the effects of two important low level perturbations in a downstream straight pipe on insertion flow meters. The aim of the work is to evaluate: i) the minimum distance between the flow meter and the perturbation that makes negligible the installation uncertainty, ii) the systematic error of different insertion flow meters.
