Corrosion-resistant high-performance flow controller

The invention discloses a corrosion-resistant high-performance flow controller. The corrosion-resistant high-performance flow controller comprises an electromagnetic flow meter, a high-pressure adjusting valve, an electric executing mechanism and an intelligent digital adjuster. The electromagnetic flow meter comprises a left metal meter body, a right metal meter body, a ceramic measuring pipe anda flow meter head. The ceramic measuring pipe is embedded into a first medium through hole and a second medium through hole. The high-pressure adjusting valve comprises a metal valve body, a first ceramic liner, a second ceramic liner, a first lip-type sealing ring, a second lip-type sealing ring, a ceramic valve bush, a ceramic valve element, a third lip-type sealing ring, a metal valve rod, a sealing sleeve and a metal valve deck. The metal valve rod is sequentially sleeved with the third lip-type sealing ring, the sealing sleeve and the metal valve deck from bottom to top, and the lower end face of the sealing sle
