We have an application where we pressurize a tanker with nitrogen to offload solvent into a storage tank. We want to measure the quantity of solvent being offloaded but are experiencing problems with 2 phase flow i.e solvent gas mixture when the tanker is almost empty. We are using a coriolis flowmeter with local indication only. It is not used for control and is not inputed into a DCS. Has anyone got any suggestions on how we can over come this problem in on order to achieve accurate flow measurements. Thanking you.
