Ultrasonic High Precision Single-use Flowmeters


The LEVIFLOW® single-use flowmeters are designed for non- invasive flow measurements of high purity fluids with flexible tubing.

All wet materials are fabricated from biocompatible (FDA, USP-VI, BSE/TSE and Animal free) gamma sterilizable polypropylene (PP).

  • All wet materials of the SU fl owmeters are made of biocompatible
    (FDA, USP-VI, BSE/TSE and Animal free) polypropylene (PP)
  • Improved bubble robustness due to DSP technology

System Configuration

The standard configuration of the LEVIFLOW® single-use flowmeters consists of a flow sensor and a converter with a digital signal processor (DSP) 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. In addition, the sensor value is shown on a 4-digit display.

For debugging, data collection and configuration with a PC the LEVIFLOW®
Configuration Software is available at Levitronix® together with a USB to RS485 adaptor.
