Velocity Interface setup
1. Install and connect your Velocity Interface controller as outlined in the
Velocity Interface user manual.
2. Install and connect your MicroFlow sensor to the Velocity Interface as
shown in Chapter 2 - Installation
– Velocity Interface
of this manual.
3. Power up the unit and enter program mode by keying in ‘ 1997
’ and
pressing Enter to begin setting up the unit for measurement.
4. If you wish to change or view the velocity measurement units, set P130
‘

’ to the selection of your choice from the options
given in the parameter list shown on the screen.
5. To change the maximum flow velocity of your application you will need
to set
P683
‘
Maximum flow velocity
’ to the desired value (in m/s).
6. To change the velocity at which the high mA output (20mA) will occur,
you will need to set
P835
‘
Output High Level

in measurement units ( P104 ).
7. All other parameters can be left at their default values, or adjusted to suit
the application, i.e. ‘P688 Gain’ and ‘P684 Damping’ can be altered to
the value range outlined in
