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 S1 is 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 S2 is detected. The presence or lack of presence of at least one gas bubble in the liquid is detected by comparing the first measured value S1 to the second measured value S2.

Abstract: A method of detecting a gas bubble in a measuring chamber is provided comprising filling the measuring chamber with a liquid; measuring the electrical conductivity of the liquid or a variable derived therefrom in the measuring chamber at a first pressure value p1, wherein a first measured value S1 is detected; changing the pressure in the measuring chamber; measuring the electrical conductivity of the liquid or a variable depending thereon in the measuring chamber at at least a second pressure value p2, wherein a second measured value S2 is detected; and detecting the presence or lack of presence of at least one gas bubble in the liquid by comparing the first measured value S1 to the second measured value S2.
