1. A crude oil flow metering device, comprising:
a measuring part, which comprises:
a measuring tube comprising a liquid inlet and a liquid outlet, an inner diameter of the measuring tube gradually increasing from the liquid inlet to the liquid outlet; and
a float assembly, which is in-built in the measuring tube and comprises a float and a float connection rod integrally connected with the float, an end of the float connection rod being connected to a detection part; and
a metering part, which comprises:
a position detection module, which is arranged in a detection cavity located above the measuring tube and formed by a first housing; in which 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;
a connection rod sleeve, which is located in the detection cavity and is in communication with the measuring tube;
a float stabilizing structure, which is connected to the end of the float connection rod, and which comprises a column and a plurality of side edges protruding from a side surface of the column in an axial direction of the column; and
a processing module, which is connected to the position detection module to calculate a flow rate of measured crude oil according to the float height detection signal,
wherein, when the float rises from a bottom end, the float connection rod and the float stabilizing structure extend into the connection rod sleeve.
