Manufacture method of four-probe conducting probe and application of conducting probe to measurement on two-phase flow parameters

The invention discloses a manufacture method of a four-probe conducting probe and application of the conducting probe to measurement on two-phase flow parameters. The manufacture method comprises the following steps: processing single-probe probes and detecting conductivity; processing and winding copper wires; insulating the single-probe probes; assembling the four single-probe probes into a location hole plate; assembling the four single-probe probes into a sleeve; injecting insulation paint into the sleeve; fixedly sealing the sleeve with epoxy resin; grinding points of the probes; and connecting rear-end circuits. The application comprises the following steps: inserting the conducting probe into the center of a pipeline to serve as an electrode, connecting a direct-current power supply with the electrode and another electrode, namely the inner wall of the metal pipeline, through a resistor, acquiring data to extract and analyze phase change signals on the conducting probe, and measuring and calculating area concentration, void fraction and interface speed of a two-phase flow local interface. The method is capable of measuring the void fraction and the interface area concentration in two-phase flow, thereby measuring forward interfaces and backward interfaces and providing reference for deeply knowing local characteristics of two-phase flowing and completing a two-fluid model.
