Non-contact oil-water double-doped intelligent flow measurement and control instrument

The utility model is applicable to the technical field of measurement and control, and provides a non-contact type oil-water double-doping intelligent flow measurement and control instrument which comprises a long pipe, a measurement and control device is fixedly installed on the outer surface of the long pipe, a fixing ring is fixedly installed at the end, away from the measurement and control device, of the long pipe, and four grooves are formed in the fixing ring. Springs are fixedly installed on the inner surface walls of the four grooves, sliding plates are fixedly installed at the ends, away from the inner surface walls of the grooves, of the four springs, when the input pipe starts to rotate, the semicircular grooves in the outer surface of the input pipe can apply pressure to the semicircular balls, and at the moment, the semicircular balls start to move towards the interiors of the grooves; meanwhile, the sliding plate can slowly extrude the spring along the inner surface wall of the groove, when the
