Disclosed is a method for determining a remaining empty volume in a container, comprising: measuring a first pressure initially prevailing in the container; feeding in a gaseous pressure-boosting medium through an inlet, into the container; measuring the increased second pressure; determining the pressure increase caused by the infeeding of the pressure-boosting medium; determining a volume of the pressure-boosting medium that has been fed into said container; measuring a temperature prevailing in the container; and determining the remaining empty volume on the basis of the pressure increase, the volume of the pressure-boosting medium, and the temperature. Disclosed also is a method for on-site calibration of a fill-level measuring device in which the volume of the medium in the container is determined on the basis of the method for determining a remaining empty volume, and an on-site calibration module.
