The LEVIFLOW® single-use flowmeters are designed for non- invasive flow measurements of high purity fluids. Illustrates the operating principle.
Two piezo-electric transducers, mounted in the sensor housing, generate and receive an ultrasonic wave. The two waves are processed by a signal converter.
The difference of the transit 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).
The standard configuration of the LEVIFLOW® single-use flowmeters consists of a flow sensor and a converter for processing the sensor signals.
Various signals (analog output, digital input/output) are provided and can be configured with a PC software.
A RS485 bus allows arrays of multiple flowmeters. The sensor value is shown on a 4-digit display.
For debugging, data collection and configuration with a PC the Levitronix® Service Software is available at Levitronix® together with a USB to RS485 adaptor.
A stackable 6-channel converter, with almost the same size as the single-channel converter, is available for high volume applications with reduced cabling effort and space need.
