Abstract: The present disclosure relates to a method for FMCW-based measurement of a distance of an object located in a waveguide, as well as a corresponding distance measurement device that, in particular, may be used for fill-level measurement in surge pipes or bypass pipes of containers. The method is based upon the fact that the transmission signal that is typical in FMCW is not ramp-like, and thus is emitted with constant frequency modulation. Rather, according to the present disclosure, a curvature of the frequency ramp is set to be at least approximately proportional to the frequency dependency of the propagation velocity of the transmission signal in the waveguide. The distortion effect is thus compensated for in that the propagation velocity of the transmission signal in waveguides is not constant, but, rather, decreases with falling transmission frequency.

Abstract: The measured volume of fuel in a storage tank of a vehicle is determined by positioning a sensor within a storage tank holding the fuel. A processor is also located on the vehicle for receiving data relative to the volume of the fuel in the storage tank, the mileage of the vehicle, and vehicle location, date, and time, for transmitting such data to a remote or centralized server (“RS”).

The RS then compares the data received from the vehicle processor with the fuel dispensed data to determine whether there are any discrepancies between the dispensed volume of fuel purchased, as indicated in the FDS data, and the measured increase of volume of fuel in the vehicle at the time of dispensing from the FDS.

Abstract: A method for checking the functional ability of an FMCW-based fill-level measuring device, which serves for measuring the fill level of a fill substance located in a container, as well as to a fill-level measuring device suitable for performing this method. For checking the functional ability, a microwave signal is produced, whose frequency change differs from the frequency change of the measurement signal used during regular measurement operation. By comparing the frequency of the difference signal resulting from the microwave signal with a predetermined reference frequency, it is ascertained, whether the fill-level measuring device is functionally able. Thus, the fill-level measuring device detects, independently, whether it is functionally able, or whether an error is present, caused principally by device-internal disturbance signals. This offers, especially, a clear advantage as regards meeting safety standards for the field device.
