Options for Q mode have the following meaning:
- flow m+ll:
- flow v+ll:
- flow m:
- flow v:
Note:
A two-channel volume metering is not possible in this configuration of the EC900.
In the EC 911 or a different version of the EC 900, in which the supply of the device is set to
battery, the flow rate measurement is blocked.
The flow rate measurement of the EC 900 is not necessarily combined with the pulse counting of
the volume sensor from the program version 11:25. Pulse counting and flow measurement can be
implemented completely independently. However, there is the possibility of creeping quantity sup-
pression and thus the influence on pulse counting and consequently on the totalizer calculation.
If the creeping quantity suppression is activated together with the flow rate measurement, alarms
are generated when the upper or lower alarm limit for the flow rate is underrun or exceeded. With-
out the creeping quantity suppression an alarm is only generated if the maximum flow limit is ex-
ceeded.
When creeping quantity suppression is activated, an exclamation mark is attached to the short text
"Qm" ("Qm!") in the flow rate display (Screen Flow, page 87) if the flow rate is below the lower limit
"QmMin" (Screen 5.1.2.0). After expiration of the maximum permissible duration of the flow below
