A fuel consumption-measuring system includes a feed line, a first pump which pumps fuel from a tank via the feed line to a consumer, a fuel consumption-measuring device in the feed line, a first return line which branches off at the consumer and opens into the feed line between the fuel consumption-measuring device and the consumer, a second return line which branches off from the feed line between the first pump and the fuel consumption-measuring device which opens into the tank, a branch which leads from the feed line into the second return line, a heat exchanger, and a flow device arranged in the first and second return lines. The flow device provides an equal volume flow at an opening of the first return line into the feed line and at the branch leading from the feed line into the second return line.

Fuel consumption-measuring system and method for measuring the fuel consumption of an internal combustion engine

A system for measuring temporally resolved through-flow processes of a fluid. The system includes an inlet, a main line comprising a line section, an outlet fluidically connected with the inlet via the main line, a displacement device arranged in the main line, a circuitous line which branches off the main line between the inlet and the displacement device and to enter the main line between the displacement device and the outlet, a pressure difference transducer arranged in the circuitous line, an evaluation and control unit which controls the displacement device, and a bypass line comprising a pump and a sensor. The bypass line branches off from the main line or from the circuitous line and ends at a same side of the displacement device and the pressure difference transducer to bypass the line section or the circuitous line from which the bypass line branches off.
