Do not under any circumstances open the converter or sensor housing.
Levitronix does not assume responsibility for any damage, which
occurs under such circumstances.
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).
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.

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-
