Abstract
An example device includes a frame having at least one outer opening and at least one inner opening recessed from the outer opening, at least one filter screen mounted on a perimeter of the at least one inner opening to form an inner chamber, and at least one cover layer mounted on a perimeter of the at least one outer chamber to form an outer chamber. The filter screen separates the inner chamber from the outer chamber, and the filter screen prevents froth from crossing and allows coalesced fluid to cross into the outer chamber.
