The LEVIFLOW® LFSC-11D.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.
No particle generation
The sensor is completely non-invasive and therefore ideal for ultrapure fluids.
The sensor is completely non-invasive and can be installed in few seconds.
±2% accuracy of reading for flows > 25% of FS
±100 ml/min for flows < 25% of FS
Up to 120° C / 248° F
The sensor is completely non-invasive and therefore ideal for hot liquids.
Suitable for high volume applications
For high volume applications, multi-channel converters are available, which can process up to 6 sensors with one single converter. The sensor signals are available over an RS485 two-wire bus or a PLC interface, thereby reducing cabling, footprint, and cost.
Smart digital signal processing
The flow converter uses a digital signal processor (DSP) to provide accurate flow measurement even when bubbles are present.
Highly dynamic flow control
The LFSC-D clamp-on flow sensor can be connected to a Levitronix® BPS pump system to provide a precise flow control.
Various parameters such as full scale, total volume, bubble detection, or high flow alarm are provided and can be configured with the Levitronix® Service Software.
