Full Scale Flow
S
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 cutoff .
In terms of flow velocity, the meter’s range is 0 .3…12 m/sec .
The full scale flow is valid for both flow directions .
OTEE: N 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 Cutoff
U
Low Flow Cutoff 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 this threshold will help prevent false
readings during “no flow” conditions possibly caused by vibrations or liquid fluctuations .
Flow Direction
S
Flow direction lets you set the meter to measure forward flow only (unidirectional) 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, the two totalizers T1+ and T2+ can be used as
totalizers and 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 .
