PULSE DOPPLER TYPE ULTRASONIC FLOWMETER

摘要

PROBLEM TO BE SOLVED: To provide a pulse doppler type ultrasonic flowmeter easily installable also in existing fluid machinery. SOLUTION: In this pulse doppler type ultrasonic flowmeter, the flow of fluid discharged from fluid machinery such as a drain pump 1 is measured by ultrasonic wave. An ultrasonic transmitting/receiving means 10 transmitting and receiving ultrasonic wave to and from the measured fluid is installed on a prefabricated pipe body 3, and the pipe body 3 is connected between the delivery side of the fluid machinery and the drain pipe 8 through a joint means 6 lengthwise adjustable in the axial direction of the pipe body 3. Since the installation of the ultrasonic transmitting/receiving means 10 is allowed by merely adjusting the length of the joint means 6 according to a distance between the discharge side of the fluid machinery and the drain pipe 8, the pulse doppler type ultrasonic flowmeter can be easily installed also in the existing fluid machinery.
