The invention discloses a conductive transducer and two-phase flow body parameter measurement device which is applied to the field of coalbed methane detection. The conductive transducer comprises a conductive shell, a direct flow body channel is formed in the conductive shell, a first connecting part is fixed to a first channel opening of the direct flow body channel, a second connecting part is fixed to a second channel opening of the direct flow body channel, a ground connecting terminal is connected to the conductive shell, and M sets of signal measurement assemblies are circumferentially distributed on the conductive shell; each set of signal measurement assemblies comprises two signal measurement assemblies distributed in the axial direction of the conductive shell, each signal measurement assembly comprises a signal connecting terminal and a conductive probe, the signal connecting terminals are arranged on the conductive shell, the back ends of the conductive probes are connected with the signal connecting terminals, and the front ends of the conductive probes are located in the direct flow body channel. Accordingly, the technical problem that needed flow body parameters for evaluating the gas yield and the coal seam working condition and predicting the yield need to be obtained by means of multiple different devices is solved, and all the flow body parameters are quickly measured.
