The invention relates to an induction type servo liquid metal liquid level measurement device and method. The device comprises a liquid level detector, a displacement sensor fixed to the liquid level detector, a servo motor controlling movement of the liquid level detector and the displacement sensor, a signal conversion and collection unit collecting signals of the liquid level detector and the displacement sensor and transmitting the signals to a controller, the controller controlling the servo motor according to the signals transmitted by the signal conversion and collection unit, and a detector power supply supplying power to the liquid level detector. By means of the induction type servo liquid metal liquid level measurement device and method, liquid level data can be measured in real time while the liquid metal liquid level changes, and engineering requirements are met. A measurement system is accurate in liquid level measurement, stable in measurement, small in maintenance amount, long in service life and free of measurement range limitation, temperature compensation does not need to be conducted, and the measurement device and method can be used in a liquid metal liquid level calibration device and continuously provide reference liquid level position data.
