Ventuary is a device for mixing fine spray of liquid with gas or measuring a flow rate of a gas. It consists of two tapered section of pipe joined by a narrow throat. The liquid velocity in the throat is increased and the pressure is reduced. Air flows through a Venturi channel at whose throat vapor enters through an opening drawn in by the low pressure. The pressure diffential can also be used to measure fluid flow.
