Flow measurement is arguably one of the most frequent tasks in any industrial environment. Apart from design challenges to ensure a good metering system, there are also installation challenges. No matter how good a design for a given flow metering system is, if the installation is not in accordance with best practices, such a flow meter will not deliver on reliability, performance and accuracy.
In non-fiscal and non-custody transfer applications, flow meters are rarely calibrated and are often left in situ for many years without any thought to their accuracy. In these applications, accuracy is not often the stated goal but maybe repeatability for control purposes but even at that some care and attention still need to be given the flow measurement set up
