Method and apparatus for monitoring a liquid loading process

A method for monitoring a loading process, in which a liquid is transported from a starting container through a pipeline into a target container, wherein the method is carried out in a data processing device, comprising the following steps:

• (a) reading measured values of the density and either the pressure or the temperature or the pressure and the temperature of the liquid transported in the pipeline from at least one measuring device,
• (b) determining an acceptable range of the density of the liquid transported in the pipeline by
• (b1) reading an acceptable range of the density or
• (b2) calculating an acceptable range of the density on the basis of the read measured values of pressure and/or temperature,
• (c) comparing the density measured value to the acceptable range, wherein the density measured value and/or the acceptable range are adapted if necessary as a function of the pressure and/or temperature measured values, so that they are comparable, and
• (d) outputting a signal if the density measured value is outside the acceptable range.

An apparatus for monitoring a loading process, in which a liquid is transported from a starting container through a pipeline into a target container, comprising a data processing device, which includes:

• means for reading measured values of the density and either the pressure or the temperature or the pressure and the temperature of the liquid transported in the pipeline from at least one measuring device,
• means for determining an acceptable range of the density of the liquid transported in the pipeline, the means for determining comprising means for reading an acceptable range of the density from an input unit and/or means for calculating an acceptable range of the density on the basis of the pressure and/or temperature measured values,
• means for comparing the density measured value to the acceptable range, which are configured so that the density measured value and/or the acceptable range are adaptable as a function of the pressure and/or temperature measured values, and
• means for outputting a signal if the density measured value is outside the acceptable range.
