Abstract

The ruling values at least two positions (16,17,18,19) determined by temp. or pressure in the system and which have variable extents are monitored whilst the system is working. - The monitored values or at least one derived from them is used in conjunction with a connection between extends relating to actual amts. of work medium in the system to determine at least an approximate value of the work medium volume.
