Abstract
Official abstract text for this publication.
A sensor for measuring a level of a liquid such as fuel and/or water in a tank such as a fuel tank. The sensor includes a stack of capacitors, each capacitor with one or more graphene measurement electrodes and one or more graphene reference electrodes. A measurement system is arranged to measure a capacitance of each capacitor between its measurement electrode(s) and its reference electrode(s) and thereby infer the liquid level. The graphene measurement and reference electrodes are formed in a single layer of graphene oxide by reductive etching.
First claim
Opening claim text (preview).
1 . A sensor for measuring a level of a liquid, the sensor comprising: a) a stack of capacitors, each capacitor comprising one or more graphene measurement electrodes; and b) a measurement system arranged to measure a capacitance of each capacitor between its measurement electrode(s) and one or more reference electrodes, wherein all of the measurement electrodes in the stack are formed in the same layer of graphene oxide. 2 . The sensor of claim 1 wherein all…
