Corrosion-resistant mass flow meter

The utility model discloses a corrosion-resistant type mass flow meter, which comprises a teflon attachment, a flange, a detection coil, a driving coil, a connecting plate, a diverter, a measuring tube, a shell, a junction box and a conducting wire, and the teflon attachment is arranged on the inner walls of a process interface, the diverter and the measuring tube so as to prevent a medium from being directly contacted with the process interface, the diverter and the measuring tube. The teflon attachment is tightly integrated with the inner walls of the process interface, the flow divider and the measuring tube, and a medium is not in direct contact with the process interface, the flow divider and the measuring tube, but is in direct contact with the teflon attachment, so that corrosive liquid is prevented from being in direct contact with a metal part of the mass flow meter, and the service life of the mass flow meter is prolonged. Therefore, the mechanical characteristics of metal parts are prevented from b
