Abstract
Apparatus and a method are described for eliminating gas bubbles from a moving liquid stream. The apparatus includes a plurality of chambers having an open top. Each chamber directs the moving liquid stream upwardly through an area of reduced diameter and then downwardly to an opening into an adjacent chamber. The bubbles are thereby urged upwardly to the top of the liquid where they burst and are vented to the atmosphere. The apparatus and method are especially useful, for example, in a turbidimeter.
