Simulated Flow
Mode
288
0 = Off
1 = On
Off
Switch simulated flow on or
off.
Simulated Flow
Velocity mm/s
289 0 – 4000 0
This sets the flow velocity in
mm/s, which can be used to
simulate velocity and mA
readings.
Sensor Reset 297 7 = Default 0
This resets all MicroFlow-i
parameters to their default
values. (It does not affect
any mA Trims applied).
Both P834 and P835 are used for spanning the mA output, by default the 4-20 mA
output span is 0 – 6 m/s. Below are some examples of the parameters use:
Example 1 : 0 – 3m/s span over 4 – 20 mA.
Set P835 to 3 (m/s).
Example 2 : 0 – 6m/s span over 4 – 12mA. Set P835 to 12 (m/s).
Example 3 : 0 – 6m/s span over 20 – 4 mA. Set P834 to 6 (m/s) and
set P835 to 0 (m/s).
Example 4: 0 – 6m/s over 8 – 20 mA. Set P834 to -2 (m/s).
Important Information
After using simulated flow, ensure that simulation mode (P288) is
switched ‘OFF’ before disconnecting the sensor from the software
and power cycling the unit.
If using the MicroFlow-i on an application where Flow type is
changed to ‘Fast’, this will reduce the damping to obtain better
results. If there is natural flow and ‘Slow’ is chosen, then damping is
increased to obtain better results.
