Abstract

A car fuel fluid transport unit has a conducting surface (10b) stretching from the lower part of the container along the filling unit (1) on the pump surface (30) and electrodes (10a) made of conducting layers on an insulating substrate on a transport unit (20) surface parallel this to form a measurement capacitor (10) to allow measurement of fluid level (2).
