Abstract:
A system for measuring crude oil as it is transported from a storage tank to a transport vessel of a transport vehicle, the system comprising:an oil conveying line adapted to convey oil from the storage tank to the transport vessel;a pump associated with said line to convey oil from the tank to the transport vehicle;a mass meter associated with said line, said mass meter capable of sensing characteristics of the conveyed oil;a microprocessor controlling said mass meter and utilizing said sensed characteristics so as to calculate the volume of oil transferred from the storage tank to the transport vessel;a recirculation conduit having a first end in fluid communication with said line on an input side of said mass meter and a second end in fluid communication with said line on an output side of said mass meter; anda diverting valve controlled by said microprocessor and coupling said conduit second end to said line, said diverting valve having a first position allowing flow into the transport vessel and blocking flow into said conduit and a second position blocking flow to the transport vessel and allowing flow into said conduit.
