2.4.2 Overview of Parameter Configuration
Table 8 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 LEVIFLOW
®
Configuration Software is needed. Consult the “Configuration-SW User Manual” (Levitronix
