Vehicle elderly level detection device

摘要

This research is about the vehicle fuel grade detection device,Fixed on the ceiling of the fuel tank, fixed the permanent magnet at the lower end of the drill magnet load that extends close to the ground, and fixed on the fuel in the tank. With the change of fuel grade, the floating body that moves to Shanghai flexibly on the above-mentioned line corresponds to the magnetic field strength of the permanent magnetic field, A power voltage generating element is installed to display the fuel level corresponding to the power voltage.
