Fuel lever arm sender (standard, ALAS and adjustable)

The fuel level in the tank is measured by means of floats (lever or tubular) which can form an integral part of the pump or be installed separately.Lever floats are used in conjunction with an electrical gauge to measure the fuel level.How do they workThe fuel contains a float which rises or falls as the level increases or decreases and, by means of a lever, operates the spring of a brush on a resistance winding or on a thick film resistor. In both cases, an adaptation to the characteristics of the tank is required.The lever floats can also be equipped with a signaling contact which, in addition to indicating the achievement of a level limit value (reserve), allows continuous measurement.The VDO lever float range includes:Without alarm contact, isolated returnWithout alarm contact, isolated return (adjustable)Without alarm contact, isolated return (special)
