The LEVIFLOW^® LFSC-09D.1 is designed for non-invasive flow measurements of high purity fluids with PFA tubing. Two piezoelectric transducers generate and receive ultrasonic waves. When flow is present, the with-stream wave is accelerated, and the against-stream wave is slowed down. The difference in transit time is proportional to the velocity of the fluid.
