The LEVIFLOW® LFS-SU inline sensor is designed for non-invasive, high precision 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. All wet materials are fabricated from biocompatible (FDA, USP-VI, and BSE/TSE free) gamma robust polypropylene (PP). For accurate measurement down to the lowest flows, special calibrated versions are available.
LEVIFLOW LFS-SU
Accuracy of Reading ±1%
Accurate measurement up to 5 bar.The sensor is made of PP and therefore ideal for high-pressure applications such as TFF or Chromatography.
Low shear and no particle generation.The measurement method is completely non-invasive and therefore ideal for delicate fluids.
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, hence reducing significantly cabling, space and costs.
Special calibrated sensors SC1.The special calibrated versions with additional calibration points at low flow values allows for accurate measurement over a very wide flow range.
FDA, USP-VI and BSE/TSE free and Gamma Robust.All wet materials are fabricated from biocompatible (FDA, USP-VI and BSE/TSE free) gamma stable (up to 40 kGy) polypropylene (PP).
Smart digital signal processing
The flow converter uses a digital signal processor (DSP) to provide accurate flow measurement even when bubbles are present.
Configurable parameters.Various signals (analog output, digital input and digital output) are provided and can be configured with a PC software.
