Method and apparatus for detection of a bubble in a liquid
First Claim
1. A method for detection of a bubble in a liquid which is placed in a measuring chamber and is in contact with a sensor for measuring the partial pressure of a particular gas in the liquid characterized in(a) performing a first measurement of the partial pressure of the particular gas in the liquid at a first pressure in the measuring chamber, (b) changing the pressure in the measuring chamber to a second pressure, (c) performing a second measurement of the partial pressure of said gas in the liquid at the second pressure in the measuring chamber, (d) providing an expected result of the second measurement based on the first measurement and assuming that no bubbles are present in the measuring chamber during any of the measurements, and (e) comparing the actual result of the second measurement with the expected result and drawing a conclusion on the presence of a gas bubble in the liquid based on said comparison.

Abstract
A method for detection of a bubble in a liquid which is placed in a measuring chamber and is in contact with a sensor for measuring the partial pressure of a particular gas in a liquid is provided. The method includes performing a first measurement of the partial pressure of the particular gas in the liquid at a first pressure in the measuring chamber. Next, the pressure in the measuring chamber is changed to a second pressure. A second measurement of the partial pressure of the gas in the liquid at the second pressure in the measuring chamber is performed. An expected result of the second measurement based on the first measurement and assuming that no bubbles are present in the measuring chamber during any of the measurements is provided. The actual result of the second measurement is compared with the expected result and a conclusion is drawn on the presence of a gas bubble in the liquid based on the comparison. An apparatus for measuring the content of a particular gas in a liquid is also provided.

10. An apparatus for measuring the content of a particular gas in a liquid comprising a measuring chamber, a sensor connected to the measuring chamber for measuring the partial pressure of said gas in the liquid and for providing at least a first and a second measurement, and means for detecting a bubble in the liquid, characterized in that the means for detecting the bubble in the liquid comprises:
-
(a) means for changing the pressure in the measuring chamber, (b) means for providing an expected result of the second measurement based on the first measurement and assuming that no bubbles are present in the measuring chamber during any of the measurements, and (c) means for comparing an actual result of the second measurement with the expected result. - View Dependent Claims (11, 12)
