10.3.14.5 MicroFlow
PLUS
/ Metering break
When handling media with a tendency to emit gas, gas bubbles form in the system after
extended downtimes, resulting in corrupted volume values of the quantity to be metered and
subsequently to the non-detection of the metering strokes by the MicroFlow
PLUS
and the
issuance of an alarm.
“Metering break” is used to set the period without metering after which the monitoring
system is deactivated for a specific time (see 10.3.14.6 MicroFlow
PLUS
/ Metering delay) to
prevent the undesired activation of the monitoring system.
Setting range:
2 - 3600s
Fig. 10.43
Default setting = 20 sec.
10.3.14.6 MicroFlow
PLUS
/ Metering delay
Use the "Metering delay" option to specify the time during which the metering monitoring
function is disabled when handling outgassing media to allow time for degassing the system.
Once the metering pause time has expired, the "Metering delay" is activated as soon as the
next metering is initiated (see chapter 10.3.14.5
).
Example:
Metering pause = 20 s, metering delay = 10 s
This example has a metering pause of 20 seconds during which metering is stopped. The
metering delay of 10 seconds is initiated with the next metering request during which the
metering monitoring of the MicroFlow
PLUS
is interrupted. Any gas bubbles can be removed
from the system without triggering an alarm during this time.
Setting range:
2 - 3600s

Default setting = 20 sec.
