ABSTRACT:
First and second ultrasonic sensors 1A and 2A are arranged facing each other, and these ultrasonic sensors 1A and 2A are provided with first and second reflectors 1 and 2 on their surface, respectively, and thereby, a propagation time t.sub.t of ultrasonic wave in a distance L within a medium subject to measurement is determined from the following equation t.sub.t =(t.sub.4 -t.sub.3 +t.sub.2 -t.sub.1)/2.
