The LEVIFLOW® LFSC-22D Flex clamp-on sensor is designed for precise, non-invasive flow measurements in bioprocessing. 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.

System Benefits

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.

No Single-Use Costs

±3% accuracy of reading for flows > 15% of FS
±360 ml/min for flows < 15% of FS

High Precision Flow Measurement

Gentle measurement principle
The sensor is ideal for shear sensitive cells and proteins due to the non-invasive measurement method.

No Additional Shear Stress

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.

Different Tube Materials and Temperatures

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.

6-Channel Converter for Multiple Sensors

Ideal for high-purity liquids
The sensor is completely non-invasive and therefore ideal for high-purity downstream and upstream processes.

No Particle Contamination

Smart digital signal processing
The flow converter uses a digital signal processor (DSP) to provide accurate flow measurement even when bubbles are present.

Improved Robustness against Bubbles

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.
