When in use, the gas enters through the left end of the connecting pipe 3. When entering the interior of the flow meter body 1 through the connecting pipe 3, the metal impurities with the head in the gas can be adsorbed by the magnet 5, and the metal impurities can be conveniently allowed to enter the interior of the absorption tank 4. When the connecting pipe 3 is in use, the sealing plug 11 is sealed and connected to the interior of the cleaning hole 10. When it is necessary to clean the interior of the absorption tank 4 with metal debris, the fixing bolt 9 is taken out, so that the sealing plug 11 loses the fixing device, and the sealing plug 11 can be conveniently taken out to push the metal impurities in the absorption tank 4 so that they can be pushed out of the cleaning hole 10. On the contrary, the fixing bolt 9 is threadedly connected to the threaded hole 13 of the sealing plug 11, so that the interior of the sealing plug 11 can be conveniently fixed. After passing through the interior of the connecting pipe 3, the gas needs to pass through the filter screen 6, and the filter screen 6 can conveniently filter other impurities in the gas.
