Process effects on Coriolis flowmeter calibration

The oil and gas industry is increasingly installing Coriolis flowmeters as an alternative to the more traditional turbine and positive displacement meters.

The oil and gas industry is increasingly installing Coriolis flowmeters as an alternative to the more traditional turbine and positive displacement meters. This is because they deliver direct mass flow and density measurement of the fluid, as well as inferred volumetric flow. These more advanced flow measurement technologies also offer diagnostic capabilities and have very few installation requirements. Although the adoption of Coriolis flowmeters seems like a logical move, several factors affecting the accuracy of Coriolis devices include temperature, pressure, fluid viscosity and Reynolds number. However, these effects are understood by meter manufacturers and corrections have been derive
