Method and apparatus for measuring the amount of entrained gases in a liquid sample
First Claim
1. An apparatus for measuring the amount of entrained gases in a liquid sample, the apparatus comprising:
- a conduit defining a volume and comprising an inlet at a lower end thereof and an outlet at an upper end thereof;
a weight measuring device coupled to the conduit for measuring a weight of liquid sample flowing through the conduit from the inlet thereof to the outlet thereof to obtain a first measurement; and
a control unit coupled to the weight measuring device for determining a difference between the first measurement and a predetermined weight value representing a weight of the same liquid sample flowing through the conduit but containing no entrained gases to obtain a calculated weight of entrained gases in the liquid sample flowing through the conduit;
and further comprising a liquid altering device for altering the liquid in the processing system as a function of the calculated weight of entrained gases in the liquid sample.

Abstract
A method and an apparatus are provided for measuring the amount of entrained gases in a liquid sample. A conduit defining a volume is provided. The conduit has an inlet at a lower end thereof and an outlet at an upper end thereof. Liquid sample is made to flow into the inlet, through the conduit, and out of the outlet. The weight of the liquid sample in the conduit is determined during a flow of liquid sample through the conduit to obtain a first measurement. Thereafter, a difference between the first measurement and a predetermined weight value representing a weight of the same liquid sample flowing through the conduit but containing no entrained gases is determined to obtain a calculated weight of entrained gases in the liquid sample flowing through the conduit.
