Abstract

An improved device and method for measuring the amount of liquid to be discharged that is present in an apparatus, such as a nebulizer. A first member has holes through which the liquid passes to be nebulized. A second member is spaced from the first member so that a volume is defined in the nebulizer by the area of mutual overlap of the first and second members and the amount of spacing between them. The first and second members are formed to establish a mutual capacitance that reflects the amount of liquid in the volume. A measuring circuit measures the capacitance existing between the first and second members and hence the amount of liquid in the nebulizer. The capacitance measurement can be used to control the supply of liquid into the volume in the nebulizer.
