Abstract: A measuring apparatus that measures a measurement target amount generated from a measurement target, includes an additional amount generating section, a sensor, and a deriving section. The additional amount generating section generates an additional amount to be added to the measurement target amount. The sensor measures a composite amount of the measurement target amount added with the additional amount. The deriving section derives the measurement target amount from an output of the sensor. The additional amount is a pulse. The pulse has an amplitude higher than the absolute value of the maximum of the measurement target amount. The maximum of the pulse is zero. The pulse has a frequency high enough to ignore the 1/f noise. The deriving section detects the output value of the sensor to derive the measurement target amount.

Abstract: The purpose of the present invention is to measure a size of a liquid droplet easily and in a short period of time by combining outputs of multiple types of liquid droplet detectors having different size dependencies of a liquid droplet of detection signals. In one embodiment of the present invention, in the detector having a narrow gap width shown in FIG. 5(a), the electrodes are electrically conducted by the attachment of a small liquid droplet.

By utilizing this, the size of a liquid droplet is determined. In a case where the liquid droplet is water, as a liquid droplet detector, for example, a detector of a type that detects a galvanic current by a cell formed by the attachment of water between the electrodes made of different kinds of metals may be used.
