ULTRASONIC FLOWMETER

摘要

PROBLEM TO BE SOLVED: To provide a flowmeter whose accuracy is satisfactory. SOLUTION: The ultrasonic flowmeter is constituted by using a pair of ultrasonic transducers 23, 24 whose correlation coefficient of a self-transmission/ reception characteristic is large. Consequently, it is possible to realize the flowmeter in which an offset value generated across the pair of ultrasonic transducers is small and whose accuracy is high.
