Conducting plastic-shelled water meter

The invention relates to a conducting plastic-shelled water meter and designs the conducting plastic-shelled water meter to solve the technical problem that existing like products are inapplicable to conducting pipes or poor in conductivity. A shell of the conducting plastic-shelled water meter comprises an outflow plastic shell and an inflow plastic shell. A core in the shell is provided with a digital display mechanism. The conducting plastic-shelled water meter is characterized in that an external thread of the outflow plastic shell is an outflow metal thread, an external thread of the inflow plastic shell is an inflow metal thread, the outside of the shell between the outflow metal thread and the inflow metal thread is provided with a conducting plate, two ends of the conducting plate contact with the outflow metal thread and the inflow metal thread to form a passage; the part of the conducting plate, on the outside of the shell between the outflow metal thread and the inflow metal thread is provided with
