The LEVIFLOW® LFSC-30D Flex clamp-on sensor is designed for non-invasive flow measurements of high purity fluids with flexible 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.
Non-invasive sensor
The sensor is completely non-invasive and can be clamped on and off in a few seconds resulting in zero single-use costs.
±3% accuracy of reading for flows > 15% of FS
±720 ml/min for flows < 15% of FS
Gentle measurement principle
The sensor is ideal for shear sensitive cells and proteins due to the non-invasive measurement method.
Select from predefined calibration sets
The sensor is calibrated for Saint Gobain C-Flex® (374, 072 and 082) and Silicone (Pharma 50, 65 and 80), and for temperatures of 20° C and 37° C.
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.
Ideal for high-purity liquids
The sensor is completely non-invasive and therefore ideal for high-purity downstream and upstream processes.
Smart digital signal processing
The flow converter uses a digital signal processor (DSP) to provide accurate flow measurement even when bubbles are present.
Smart sensor
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.
