Full Scale Flow
This parameter sets the maximum flow the system is expected to
measure. This parameter has influence on other system parameters
like analog output or low flow cut-off.
In terms of flow velocity, the meter’s limit are from 0.1 to 12 m/sec.
The full scale flow is valid for both flow directions.
Note: If the flow rate exceeds the full scale setting, an error message
indicates that the configured full scale range has been exceeded.
Low Flow Cut-off
Low Flow Cut-off defines the threshold at which flow measurement will
be forced to zero. The cutoff value can be from 0 % to 10 % of the full
scale flow. Increasing the threshold will help prevent false reading
during “no flow” conditions possible caused by vibrations or liquid
fluctuations.
Flow Direction
Flow direction lets you set the meter to measure forward flow only (uni-
directional) or both forward and reverse flow (bidirectional).
Unidirectional means that the flow is totalized in only one direction.
The flow direction is indicated by the arrow printed on the detector
label. In this mode, T1+ can be used as overall and T2+ as resettable
day counter.
Bidirectional means the flow is totalized in both directions. The totalizer
T1+ and T2+ registers forward flow and the totalizer T1- and T2- in
reverse flow direction. The net totalizer T1N and T2N shows the
difference between T+ and T-.
A change of the flow direction can be signalized by the digital outputs.
Filter
Median
The Median Filter (MDN) reduce noise on the
measuring signal. The filter level can be adjusted
from 7 up to 13 or switched off.
