High-precision two-way metering rotor dry-type pulse water meter

The invention relates to the technical field of water meters, and discloses a high-precision two-way metering rotor dry-type pulse water meter which comprises a water meter whole body, the water meter whole body comprises an upper meter body A at the top and a lower meter body B at the bottom, according to the high-precision two-way metering rotor dry-type pulse water meter, in order to prevent the lower meter body B from being polluted, a filter screen is arranged in a water flowing through hole; in order to isolate dirt to the maximum extent, the diameters of the holes in the filter screen are small, the number of the holes is large, and therefore under the condition that circulation is guaranteed, various kinds of dirt are isolated from entering B to the maximum extent, the situation that the dirt disturbs work of the whole water meter, and consequently reading is not accurate is avoided, and in addition, due to the fact that the diameters of the holes in the filter screen are small, and the number of the
