An apparatus for determining the identity and/or quantity of a liquid fuel contained in a fuel transporting tank of a fuel transporting vehicle can comprise: a longitudinally extensive member having a first end and a second end, an internal volume from which liquid fuel in the tank is excluded, and a mounting arrangement configured for mounting in use of the longitudinally extensive member within and in fixed relation to the tank, said second end configured in use to be immersed in the liquid fuel in the tank. The longitudinally extensive member can further comprise: first and second pressure sensors spaced apart by a fixed distance, each said pressure sensor having a face exposed in use to the local hydrostatic pressure of the liquid fuel in the tank;and a colour sensing device comprising a light emitter and a light detector configured to detect light from the emitter, said emitter and detector being arranged such that in use light from the emitter incident on the detector passes through said liquid fuel in the tank. The apparatus can further comprise a data processing device configured to determine the identity of the liquid fuel based on said pressure measurements from said first and second pressure sensors and colour data from said colour sensing device.
