T/LL350 series fuel level sensor The Model T/LL350 series is a range of highly advanced sensors for continuously measuring the contents of a fuel tank. The unique feature of the T/LL350 is that it recalibrates itself when a liquid with a different dielectric constant is used. For example, if it is used in a tank of conventional diesel, then the user can refill with bio nk bio-diesel and the sensor will correct the output level automatically. A low level alarm switches when the fuel drops below a predetermined level (default is 1/8th of the tank), but the alarm point can be optionally specified anywhere between 0 0100%.
