Double-pipe electromagnetic flow machine with anti-permeation function

The utility model is applicable to the technical field of electromagnetic flow machines, and provides a double-tube electromagnetic flow machine with an anti-permeation function, which comprises a double-tube electromagnetic flow machine main body, the two ends of the double-tube electromagnetic flow machine main body are fixedly connected with mounting plates, and a plurality of fixing holes are formed in the surfaces of one sides of the two mounting plates and are arranged at equal intervals. When the double-tube electromagnetic flow machine is used, the insulating layer is coated inside the double-tube electromagnetic flow machine main body, the double-tube electromagnetic flow machine main body is communicated with a pipeline, a constant magnetic field is formed inside the double-tube electromagnetic flow machine main body through the two magnet exciting coils, and when conducting liquid flows, the two electrodes measure induced voltage; the induced voltage is in direct proportion to the flow velocity of
