A measuring system for measuring a mass flow rate, a density, a temperature or a flow velocity. The measuring system includes a main line, a first Coriolis measuring device arranged in the main line, a second Coriolis measuring device arranged in series with the first Coriolis measuring device in the main line, a bypass line which bypasses the second Coriolis measuring device, a first valve arranged in the bypass line, and a computing unit which is connected to the first Coriolis measuring device and to the second Coriolis measuring device. The first valve opens depending on a pressure. The first Coriolis measuring device is designed for a higher maximum flow rate than the second Coriolis measuring device.

A pressure-regulating device for a fuel consumption measurement system includes a fuel supply line which supplies fuel to a consumer, a fuel return line, a bypass line which branches off from the fuel supply line, a pressure regulator which sets a free flow cross-section in the bypass line, a pressure sensor arranged at the fuel supply line downstream of where the bypass line branches off, a control unit electrically connected to the pressure sensor, and a pressure-reducing element arranged in the fuel supply line upstream of the pressure sensor and downstream of the branch of the bypass line. The bypass line fluidically connects the fuel supply line to the fuel return line and feeds fuel from the fuel supply line to the fuel return line while bypassing the consumer. The pressure sensor provides pressure measurement values. The control unit regulates the pressure regulator depending on the pressure measurement values.
