1. A pressure vessel system in a motor vehicle, the pressure vessel system comprising:
a pressure vessel in the motor vehicle for storing gaseous fuel;
a fuel line connected to the pressure vessel;
a total-pressure sensor connected to the fuel line for measuring a total pressure of the gaseous fuel at a position within the fuel line, wherein
the total-pressure sensor is configured to measure the total pressure in both directions of flow, the total-pressure sensor being rotatably connected to the fuel line,
the total-pressure sensor is rotatably designed, so that an inlet opening can be kept in both directions of flow, and
the total-pressure sensor is configured to measure the total pressure when the gaseous fuel is flowing away from and toward the pressure vessel.
