Easy-Setup Clamp-On Ultrasonic Flowmeter
A clamp-on ultrasonic flowmeter is the only flowmeter that can be installed on existing pipelines without draining and plumbing. In conventional clamp-on ultrasonic flowmeters, the relative position of transducers depends heavily on the properties of the pipe on which the transducers are mounted.

A Propagation Time Difference Evaluation for a Clamp-On Ultrasonic Flowmeter for Low-Pressure Gas
Abstract We have been studying the development of a clamp-on ultrasonic flowmeter for measuring the gas flow rate, especially at low-pressure gas such as atmospheric pressure. In this study, we evaluated the propagation time difference of ultrasonic wave for measuring the airflow at atmospheric pressure. We placed a pair of ultrasonic
