Claim Text:
1. A device for measuring a fuel flow, the device comprising: a measuring module operable to measure a fuel flow guided through the measuring module; a conditioning module downstream of the measuring module and operable to condition the fuel; a verification module downstream of the measuring module and operable to check the measuring precision of the measuring module, the verification module installed firmly and permanently as an integral part of the device and connected with the measuring module such that the fuel can be guided from the measuring module downstream to the verification module; a main pipe for guiding the fuel from the measuring module to the conditioning module; and a secondary pipe branching off to the verification module from the main pipe at a branching point, wherein the verification module has a dosing unit with a fuel injector unit operable to extract an exactly defined quantity of fuel serving as a reference fuel quantity, wherein the measurement fuel quantity determined by the measuring module and the reference fuel quantity determined by the dosing unit are comparable in order to determine a measuring precision of the measuring module.
