<p>An apparatus is proposed for indicating the level of fuel or other liquid contained in a tank. The apparatus consists of a cylindrical casing closed at its two ends by two suitably shaped disc-like covers, and internally comprising two guides on which there slides a float provided with a slot within which there is engaged a rod having its ends connected to a rotary moving element which comprises on its top a contact which slides along a resistor installed on the upper disc-like cover of the cylindrical casing. As the height of the float varies within the cylindrical casing, which is suitably holed to allow the liquid to enter or leave, the position of contact along the resistor varies with corresponding variation in the electrical signal measured at its output. <IMAGE></p> |
