<p>An acoustic droplet emitter with a liquid level control plate (42) having a lip in intimate contact with the free surface (18) of a liquid (14) is constructed. The liquid level control plate (42) also has an effective aperture diameter (Aw) at the exit edge of the plate which is larger than the effective aperture diameter at the lip. This reduces the pressure sensitivity of the free surface of the liquid and allows for the free surface of the liquid to be effectively pinned at the bottom surface of liquid level control plate for wider variations in pressure than using conventional methods. <IMAGE></p> |
