[0002] A solar water heater is a heating device that converts sunlight energy into thermal energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form. Vacuum collector tubes use the principle that hot water floats and cold water sinks to produce microcirculation of water to obtain the required hot water. In order to facilitate users to know the water level in the solar water heater, a water level measuring device needs to be installed on the solar water heater. Current water level measuring devices usually use the buoyancy of water to measure the water level.
