Liquid level measuring device suitable for urea solution storage tank

The utility model relates to a liquid level measuring device suitable for a urea solution storage tank, which comprises a magnetic turning plate liquid level meter arranged on the urea solution storage tank, the periphery of a main body pipeline of the magnetic turning plate liquid level meter is wrapped with a heat preservation layer, and an electric tracing band wound on the periphery of the main body pipeline is arranged between the heat preservation layer and the main body pipeline. The magnetic turning plate liquid level meter is installed on a urea solution storage tank, the electric tracing band is electrified, the urea solution on the main body pipeline of the magnetic turning plate liquid level meter is kept at 50-60 DEG C all the time, the urea solution in the main body pipeline of the magnetic turning plate liquid level meter cannot be crystallized due to temperature reduction, the liquid level is checked on site through the magnetic turning plate, and measurement is accurate.
