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.
