    Patent number: 4550590
    Abstract: There is described a method of and apparatus for monitoring the concentration of gas in a liquid. The apparatus includes a semi-permeable diaphragm across the face of which the liquid flows. Gas contained in the liquid permeates through the diaphragm into a chamber and the pressure within the chamber is measured. This pressure is representative of the concentration of gas in the liquid and permits control of the quantity of gas injected.
