Product Description:

LEVIFLOW® LFS Series
Ultrasonic High Precision Non-invasive Flow Measurement

LEVIFLOW®flowmeter series are designed for non invasive high precision flow measurements of high purity fluids.

Five flow sensor sizes are available to measure flows from the ml/min range up to 80 l/min.

LFS Flowmeter Series – Flow Ranges

LFS-008: 0 – 0.8 l/min
LFS-04: 0 – 4 l/min
LFS-08: 0 – 8 l/min
LFS-20: 0 – 20 l/min
LFS-50: 0 – 50 l/min
LFS-80: 0 – 80 l/min

Standard and Multi Channel Configuration
For high volume applications a multi-channel converter is available, which processes 6 sensors with one single converter. The sensor signals are available by MODBUS interface (RS485), hence reducing significantly cabling, space and costs.

Various signals (analog, digital input and digital output) are provided and can be configured with a PC software. A two wire RS485 bus allows arrays of multiple flowmeters where sensor signals can be received by MODBUS protocol. In addition, the sensor value is shown on a 4-digit display.
The standard configuration of the LEVIFLOW® flowmeters consists of a flow sensor and a converter with a digital signal processor (DSP) for processing the sensor signals.
