Magnetic turn-over plate liquid level meter

The utility model discloses a magnetic turn-over plate liquid level meter, which comprises a buoy, a float and a magnetic turn-over plate, wherein the float is provided with leakage grooves, and the leakage grooves are evenly arranged on the float, thereby enlarging the liquid flow area between the float and the buoy, enabling excess liquid entering into the liquid level meter from an upper port to smoothly flow into a container through the leaking grooves, and keeping the liquid level in the buoy the same as that in the container, and enabling the float to stably float in the liquid level, thereby accurately measuring the liquid level in the container. The magnetic turn-over plate liquid level meter has simple operation and accurate measurement, which solves the problem of inaccurate measurement caused by flowing excess liquid phase medium into the magnetic turn-over plate liquid level meter from the upper port, when high-temperature medium in the container is easy to condense or have severe vapor-liquid pha
