ABSTRACT:
A method of detecting a gas bubble in a measuring chamber filled with a liquid. The electrical conductivity of the liquid or a variable derived therefrom is measured in the measuring chamber at a first pressure value p1, and a first measured value S1is detected. The pressure in the measuring chamber is changed, the electrical conductivity of the liquid or a variable depending thereon is measured in the measuring chamber at at least a second pressure value p2, and a second measured value S2is detected. The presence or lack of presence of at least one gas bubble in the liquid is detected by comparing the first measured value S1to the second measured value S2.
