*The sensor is supplied in the following standard sizes corresponding to the height of automotive fuel tanks: 700,
500, 350, 300, 180 mm. Sensors of non-standard lengths are available on special order.
4 Construction and Principle of Operation
The sensor operates on the principle of capacity measurement. The sensing assembly of the sensor
consists of two concentric tubes which form a cylindrical capacitor.
The
assembly’s
capacity depends on the level
to which the tubes are immersed in the LFL.
