We are trying to accurately measure oil coming into our refinery. Currently, we use a coriolis meter and a capacitance probe to measure volume and 5S&W coming into our receiving tanks. However, we are having issues with errors that are introduced due to variance in oil density and %S&W.
We are looking at a system that finds the density of the oil and the density of the brine. The system will automagically perform a NOC calc based on the live density vs these known densitys, and calculate %S&W if the capacitance probe is outside its working range.
We need to decide the type of meter we want to used. Should we use a gear driven PD meter or a coriolis meter. My understanding is a PD meter is more repeatable, but the coriolis meters are more accurate. Any thoughts?
