The LEVIFLOW® LFS inline sensor is designed for non-invasive high precision flow measurements of high purity fluids. 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. The wet material is made from PFA and resistant against harshest chemicals.
