Abstract of the Disclosure Pneumatic nebulizer and method for uniformly introducing variable small amounts of flowable liquid into a gas flow to form a stable dispersion having the appearance of a natural fog and consisting essentially of microscopic liquid particles of said liquid dispersed in said gas. The nebulizer comprises a mixing element for introducing the liquid in uniformly fine amounts into the gas flow. The mixing element, which preferably is a replacable unitary element, comprises two superposed members which provide therebetween at least one shallow liquid orifice, at least a portion of the surfaces of said members either being in conforming surface contact with each other in the area between the entrance and the exit of said liquid orifice during use, or being capable of flexing towards or away from such conforming surface contact in said area under the effects of the force of said liquid and/or said gas during use. The liquid orifice has its entrance in communication with a liquid supply chamber and has its exit in communication with a gas passage for metering uniform predetermined amounts of liquid into a gas flowing through said gas passage. The shallow liquid orifice is formed between the said superposed members by providing the surface of one or both members with at least one narrow shallow recess such as formed by a scratch, grind, etch, press, discontinuous coating etc., or by using a flexible member, to provide at least one shallow liquid orifice which has a depth of about 0.01 inch or less, during use for introducing uniform fine amounts of liquid from a liquid supply into the gas passage for admixture with the gas flowing from a gas supply.
