摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic liquid level meter of a simple configuration and low power consumption capable of measuring the height h of a liquid surface up to a level close unlimitedly to zero with high accuracy.

Even when the height h is small, moreover even when the height h is close unlimitedly to zero, the height can be measured with high accuracy. COPYRIGHT: (C)2009,JPO&INPIT
