Overview Of Parameter Configuration - Levitronix LEVIFLOW LFS-SU User Manual

2.3.3 Overview of Parameter Configuration

Table 6 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 Levitronix
Software is needed. Consult the "Service Software User Manual" (see reference on title page of this manual)
for more detailed description.

- Upper flow limit detection
- Lower flow limit detection
Flow alarm High
- Flow volume detection first value (one-time)
- Flow volume detection second value
- Pulse per volume
- Error signal (empty sensor etc.)
- Flow as Frequency output (100% of full-scale = 1 kHz)
Flow alarm Low
- Bubble detected signal
- Bits of equipment status can be OR-ed on the output
0 % Can be used to get tolerance to noise.
105 % Alarm setting In percentage of full-scale.
N.O. = norm. open For digital outputs of converter.

During this time instant measurement errors are ignored.
10s If an instant measurement error stays active for longer
time than this time, measurement error arises.
