摘要： The present disclosure relates to a crude oil flow metering device, which includes a measuring part and a metering part; the measuring part includes a measuring tube and a float assembly; the float assembly is in-built in the measuring tube, and includes a float and a float connection rod integrally connected with the float; an end of the float connection rod is connected to a detection part; the detection part protrudes out of the measuring tube when the float rises from a bottom end; the metering part includes a position detection module and a processing module; the position detection module is arranged in a detection cavity located above the measuring tube and formed by a first housing; when the detection part at the end of the float connection rod extends into the detection cavity, the position detection module detects a position of the detection part at the end of the float connection rod to obtain a float height detection signal; and the processing module calculates a flow rate of measured crude oil according to the float height detection signal. The present disclosure can safely meter the crude oil flow of a crude oil transport pipeline and meet the accuracy of metering crude oil.
