2.4 Overview of Parameter Configuration
Table 3 shows the standard (“Default”) and possible parameter configurations of the flowmeter. 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

Doc.# PL-4501-
00) for more detailed description.
Note: The LFIF-06 flowmeter needs configuration software version V1.34 or higher.

Low cutoff
0.0 – 25.0 %

Flow cut to 0 below this percentage of full-scale
If cutoff 0% is chosen, negative flow becomes visible

With the LFE-E.3 cable the current can be converted into
0 – 10 V voltage.
Digital output

Digital output
Flow alarm High
Flow alarm Low

Measurement Error
Flow as Frequency
Digital Output Off
Measurement Error
- Upper flow limit detection
- Lower flow limit detection
- Pulse per volume
- Error signal (empty sensor etc.)
- Flow as Frequency output (100% of full-scale = 1 kHz)
- Set digital output off
Flow alarm

Can be used to get tolerance to noise.
Alarm high
0 – 125 %
105 %
Alarm setting In percentage of full-scale.
Contact type
N.O. = normally open
N.C. = normally closed
N.O. = norm. open
For digital output.

During this time instant measurement errors are ignored.
If an instant measurement error stays active for longer
time than this time, measurement error arises.
