LEVIFLOW Single-Use Flowmeter

LEVIFLOW® LFSC-SU Flowmeter Series

Ultrasonic High Precision Single Use Flow Sensors

ESI Ultrapure have the best solution for your flow measurements requirements. The LEVIFLOW® flowmeter series are designed for non-invasive high precision flow measurements of high purity fluids with flexible tubing.

Flow Measurement

Two piezoelectric transducers, mounted at both ends of the measuring path of the fluid stream, generate and receive an ultrasonic wave. The wave going in direction of the flow (with-stream wave) is accelerated and the wave going against (against-stream wave) the flow direction is slowed down. The two waves are processed by a signal converter. The difference of the transmit time of both waves is proportional to the velocity of the fluid. The wet materials of the single-use sensors fabricated from biocompatible (FDA, USP-VI, BSE/TSE and Animal free) gamma sterilizable polypropylene (PP).
