DP Meter Diagnostic Systems – Operator Experience
Abstract/Introduction-
In this paper, first field tests of Prognosis were carried out by BPCATS and ConocoPhillips TGT and reported to the NSFMW in 2010 by Skelton et al [3]. Since thenPrognosis has been further developed and applied in the field to orifice and Venturi meters by severaloperators. This paper describes these developments and the field experience of these operators.

Abstract/Introduction-
This paper describes about the Different linearization techniques and can be chosen to subtly modify flow meter output without necessarily violating any contract, standard, or accepted norm. If linearization techniques are not fully disclosed then in reality the end user does not know the true flow rate prediction uncertainty of that meter across its flow range.
