Flow Conditioning – A Technology Research Updated

Inferential meters, such as orifice, turbine and ultrasonic meters, infer fluid flow based on an observed meter output combined with a number of fluid flow assumptions. Optimal flow conditions lead to optimal meter performance and in some cases “fully developed turbulent pipeline flow” is used to describe these optimal flow conditions. Unfortunately, the length of long/straight/uniform/clean pipe required to produce “fully developed pipeline flow” often exceeds practical installation constraints. Although flow conditioning has been successfully used to create optimal flow conditions and reduce meter run lengths, problems can still exist if they are incorrectly applied. This overview presents material available from the literature, which describes some of the installation effects that need to be managed
