レベル七A large-diameter metal diaphragm with a piezoelectric ceramic harmonizer affixed to the inner surface is bonded to the lower end surface of a tubular metal holder that is attached to a tank containing a liquid whose level is to be detected so that it can be bent and moved. The piezoelectric level 7 is characterized in that a recess is provided in the vibrator so that a portion of the metal sliding plate to which the piezoelectric ceramic vibrator is attached projects inwardly from the lower end surface of the liquid ruler.
