The invention discloses a plug-in magnetic float liquid level meter with a temperature self-adaption system. The plug-in magnetic float liquid level meter comprises a power source, a sampling resistor, a rectifying circuit, an AVR single chip microprocessor, a temperature sensor, a digital positioned and a current signal output end, wherein the power source is connected with the sampling resistor, the AVR single chip microprocessor and the temperature sensor, the sampling resistor is connected with the current signal output end through the rectifying circuit, and the AVR single chip microprocessor is connected with the current signal output end. In this way, the plug-in magnetic float liquid level meter with the temperature self-adaption system improves measuring accuracy of the actual liquid level, greatly improves detection accuracy and reduces deviation (from 6% to 0.3%), meanwhile, the service life of the plug-in magnetic float liquid level meter is prolonged, and safety of the plug-in magnetic float liqu
