3500 ELECTROMAGNETIC FLOW METER
ONICON Incorporated 727.447.6140 Page 39 onicon.com
Meter Settings:
The user can set Meter Mode to be Unidirectional (for a pipe
with ow in one direction) or Bidirectional (for a pipe with ow
in two directions). Sensor Type is set by ONICON and cannot
be updated in the eld.
Note: Mode Indication on the main screen will indicate
the ow mode status based on the Meter Mode selection.
If bidirectional is selected, the main screen will show
Forward vs Reverse ow depending on the direction of the
measured ow. If the mode is selected as single, the meter
will show forward mode in normal condition and will go to
an alarm if it is on reversed ow.

Field Characterization:
Flow Characterization allow the user to congure the ow
reading based on eld data and conditions.
Filter Mode: Selection between Slow, Medium, Fast
Advanced / Slow: This lter allows
the user to read ow without
much reading uctuation due to
environmental noise environment
or ow disturbance on challenging
installations like elbow or tee.
Advanced / Medium: ONICON
Default lter
Advanced / Fast: This lter setting
can be used if the meter needs to
react faster to ow changes.
Flow Cut-o: This is the minimum value the meter will read
before reporting 0.
K-Factor: Multiplier of the main ow rate measurement.
Changing this value will void the calibration of the meter. A
proper balance method should be followed before changing
this number.
