Abstract
Abstract Titration potential measurement providing means including both method and apparatus for eliminating the interference of gas accumulations in the titrated sample to interfere with accuracy of potential measurement. This is accomplished by flowing the titrated sample through a potential measuring chamber having an upper and lower flow path for the titrated sample, with two spaced electrodes extended into the lower flow path, whereby gas accumulations in the sample will rise to the upper flow path, while measurements are made in the relatively gas free portions of the sample in the lower flow path.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
46 words
Means as in claim 1 in which the first of said electrodes encountered by the fluid flowing along said lower flow path is a measuring electrode, and the second of said pair of electrodes is spaced downstream of said first electrode and is a reference electrode.
Claim 2
Dependent Claim
35 words
Means as in claim 1 in which said chamber is coupled to a fluid flow system to receive the sample by a nipple having an internal diameter less than the diameter of said flow paths.
