Measure
Low Flow Cutoff
U
Low flow cutoff defines the threshold at which flow measurement will be forced to zero . The cutoff
value can be set from 0% to 10% of the full scale flow . Increasing this threshold will help prevent false
readings during “no flow” conditions possibly caused by pipe vibration or inherent system noise .
Flow Direction
S
This parameter allows setting the meter to measure forward flow only (unidirectional) or both forward
and reverse flow (bidirectional) .
Unidirectional
Flow is totalized in only one direction . The flow direction is indicated by the arrow printed on the
detector label . Unidirectional measurements on the main display screen include:
T1: Registers forward flow, resettable by menu or Modbus RTU .
T2: Registers forward flow, non-resettable .
Bidirectional
Flow is totalized in both directions . Bidirectional measurements on the main display screen include:
T1+: Registers forward flow, resettable by menu or Modbus RTU
T1-: Registers reverse flow, resettable by menu or Modbus RTU
T1N: Registers total flow, T+ - T-, resettable by menu or Modbus RTU
T2+: Registers forward flow, non-resettable
T2-: Registers reverse flow, non-resettable
T2N: Registers total flow, T+ - T-, non-resettable
T1 Reset
S
This parameter allows the reset of totalizer T1 .
Median This parameter can be set to ON or OFF . When set to ON, the median display filters out the flow rate
fluctuations displayed on the LCD .
Filter Display This parameter can be set from 0…99 seconds . The display will update less frequently, depending on
how high the filter display is set .
