1. A crude oil parameter detection device, comprising:
a liquid cavity, which is constituted by a first housing and comprises a first liquid inlet and a first liquid outlet;
a flow measurement cavity, which is constituted by a second housing and in-built in the liquid cavity, and comprises a second liquid inlet and a second liquid outlet, the second liquid outlet being in communication with the first liquid outlet through a liquid outlet pipeline;
a float assembly, which is in-built in the flow measurement cavity, 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;
a detection cavity, which is constituted by a third housing, and at least internally comprises a position detection module;
a connector, an upper part of which is fixed to the third housing constituting the detection cavity, and a lower part of which is connected to the first housing constituting the liquid cavity and the second housing constituting the flow measurement cavity respectively, in which the connector is provided with a through hole, and the end of the float connection rod can extend into the detection cavity via the through hole; and
a processing module, which is configured to be at least connected to the position detection module, 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; and the processing module calculates a flow rate of measured crude oil according to the float height detection signal.
