By Tom O Banion, Micro Motion I: Verifying Coriolis fl ow meter calibrationAdvanced diagnostics help this technology s reliability. The perfect flow meter, as described by George Mattingly, , of the National Institute of Standards and Technology (now retired), never drifts or wears. It never needs zeroing and measures in mass units. It is immune to the effects of changing fluid properties and fluid dynamics, density, viscosity, Reynolds number, speed of sound, swirl and irregular flow profile. It has virtually zero pressure drop. It fea-tures advanced diagnostics capable of thoroughly checking any abnormal conditions, perhaps sending text messages to relevant stakeholders to provide advanced notice and guidance on how to remedy the condition.
