Operating Instructions, 02/2016, A5E33120874-AC
Parameter Description
Low Massflow Cut- Set massflow limit for low
Off flow cut-off.
Below this limit massflow
output is forced to zero.
If Low Flow Cut-Off is set to
0, the cut-off functionality is
disabled.
Notice:
It is recommended to set a
lower value for gas applica-
tions.
Massflow Correction Specify correction factor for
Factor use in the massflow calcula-
tion
Parameter Description
Low Volumeflow Define the numerical volume-
Cut Off flow value below which the
volume flow output is forced
to zero.
Parameter Description
Empty Tube Limit Define threshold value of
empty tube
Empty Tube Set automatic detection of
Detection Empty Tube On/Off
0 = off (Empty tube is off).
1 = on (a density value
below Empty Tube Limit
triggers an alarm. All flow
rate values are forced to
zero %).
