Measurements
Low Flow Cutoff
[0 2%]
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
To change the Low Flow Cutoff value, follow these steps from the Measurements menu:
1 Select Low Flow Cutoff to view the Low Flow Cutoff display
2 Set the low flow cutoff value to the desired setting
3 Press [E] to save the new low flow cutoff value
Flow Direction
[Bi-Directional]
U
Flow Direction lets you set the meter to measure forward flow only (uni-directional) or both forward and
reverse flow (bi-directional)
Uni-Directional
Flow is totalized in only one direction The flow direction is indicated by the arrow printed on the
detector label Uni-directional measurements on the main display screen include:
•
T1: Registers forward flow, resettable by menu or MODBUS RTU
• T2: Registers forward flow, resettable by menu, MODBUS RTU, or digital input configured for
Remote Reset
Bi-Directional
Flow is totalized in both directions Bi-directional measurements on the main display screen include:
•
T+: Registers forward flow, resettable by menu or MODBUS RTU
• T–: Registers reverse flow, resettable by menu or MODBUS RTU
• TN: Registers total flow, T+ – T–, resettable by menu or MODBUS RTU
To change the flow direction follow these steps from the Measurements menu
1 Select Flow Direction to view the Flow Direction display
2 Select Uni-Directional or Bi-Directional
3 Press [E] to save the flow direction and return to the Measurements menu
Damping Factor
[No Damping]
U
The damping factor establishes the stability of the measured flow rate If back and forth oscillations of
the flow rate are observed during normal flow conditions, increase this value incrementally until the
flow rate stabilizes This parameter has no affect on the totalizers
To change the Damping Factor value, follow these steps from the Measurements menu
1 Select Damping Factor to view the Damping Factor display
2 Select one of the following damping factors:
1 Second 10 Seconds
2 Seconds 20 Seconds
3 Seconds 30 Seconds
4 Seconds No Dampening
5 Seconds
3 Press [E] to save the damping factor and return to the Measurements menu
