User Manual for LEVIFLOWTM LFS Flowmeters
www.levitronix.com
This manual contains information necessary for the safe and proper use of the LEVIFLOWTM flowmeter series. Included are specifications for the standard configuration, components, and instructions regarding its use, installation, operation, adjustment, inspection and maintenance. For special configuration of the LEVIFLOWTM flowmeters refer to accompanying information. If the flowmeters have to be configured for other parameter settings then the
LEVIFLOWTM configuration software (with according manual Levitronix Doc.# PL-4501-00) is necessary. Please
familiarize yourself with the contents of this manual to ensure the safe and effective use of this product. After reading, please store the manual where the personnel responsible for operating can readily refer to it at any time.

CAUTION
Do not under any circumstances open the converter or sensor housing. Levitronix does not assume responsibility for any damage, which occurs under such circumstances.
WARNING
Hazardous voltage may be present.
In case of the usage of an inadequate AC/DC power supply, mains voltages may be present (even if the system is designed for 24VDC).
The converter must be placed in a spill protected environment. Do not under any circumstances open the powered converter.
The usage of galvanic separated AC/DC supply is highly recom­mended (preferable with UL 1950, UL 508C and/or IEC/EN60950).
WARNING
TOXIC CHEMICALS may be present.
When using the flowmeter to measure chemicals skin contact and toxic gases may be hazardous to your health. Wear safety gloves and other appropriate safety equipment.

2.4.2 Overview of Parameter Configuration
Table 7 shows the standard (“Default”) and possible parameter configurations of the flowmeters. This user manual is dealing with the standard configuration. For setting up other configurations the LEVIFLOWTM
Configuration Software is needed. Consult the “Configuration-SW User Manual” (Levitronix Doc.# PL-4501-
