An apparatus for monitoring consumption of flowing substance is provided. The apparatus, connectable to the end of a pipe where fluid is flowing, includes a generator (106) configured to generate electric power from the fluid passing through the generator, sensors (112, 114) to measure the temperature of the fluid and the amount of fluid flowing in the pipe and a processing unit (116). The apparatus detects that fluid starts flowing in the pipe at a first time instant and detects that fluid stops flowing in the pipe at a second time instant and determines the temperature of the fluid and the amount of fluid that flowed through the pipe between the first and the second time instant, stores the determined values and the time elapsed between the first and the second time instants as an entry in a memory (120); and transmits the entry.

A method and a system for determining a fuel consumption of a vehicle. The method comprises determining a fuel consumption based on a consumption-dependent variable and based on at least one standard value of a fuel material property. The method further comprises determining a fuel material property of the fuel used by the vehicle, calculating a correction value based on the determined fuel material property, and determining a corrected fuel consumption based on the determined fuel consumption and the correction value. In particular, the net CO.sub.2 emission or the greenhouse gas emission can be determined from the renewable share.

A system and method of calculating a vehicle DTE are provided to calculate a fuel efficiency of each vehicle drive mode, and display a more accurate DTE of each drive mode. The method includes when a driver selects a drive mode and a drive distance of the selected drive mode is accumulated while a vehicle is being driven in the selected mode, collecting drive data including an accumulated drive distance of each drive mode, and fuel efficiency information of each drive mode. A final fuel efficiency of each drive mode is calculated using a drive distance of each drive mode, a consumption energy of each drive mode or a fuel efficiency of each drive mode, and a learning fuel efficiency. A DTE of each drive mode is then calculated based on the calculated final fuel efficiency of each drive mode.
