This chapter explains the quickest way in which to get your MicroFlow sensor
working with the Pulsar controllers that the sensor operates with.
FlowCERT setup
1. Install and connect your FlowCERT controller as outlined in the
FlowCERT user manual.
2. Install and connect your MicroFlow sensor to the FlowCERT as
described in Chapter 2 - Installation - FlowCERT of this manual.
3. Power up the unit and enter program mode by keying in ‘ 1997
’ and
pressing Enter to set-up an application for ‘area velocity’. This can be
done by choosing option 4 in Quick set-up or directly changing
P700 to
4 = ‘ Area velocity
’.
4. Continuing with the Quick setup, you now need to select the Primary
Measuring Device (PMD) for your application from the options displayed
on screen.
5. Once you have selected your application you will then be asked a series
of questions, which are answered by selecting the appropriate option you
require. For further information on the Quick set-up of a FlowCERT
please refer to
Chapter 6 Quick Set-up Guide in the FlowCERT user
manual.
6. Once you have selected area velocity, set P130 ‘ Device Mode
’ to
2 =
‘
Speedy
’ (‘
Velocity
’ in Ultra firmware versions 7.4.4 and onwards) to
enable the velocity parameters.
7. 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)
8. All other velocity parameters can be left at their default values or can be
adjusted to suit the application, i.e. ‘P688 Gain’ and ‘P684 Damping’ can
be altered to the value range outlined in
Chapter 7 – Parameter Listing
and Descriptions of this manual.
9. When a level transducer is also connected, to view the instantaneous flow
velocity measurement on the auxiliary display of the FlowCERT,
P815
‘
Auxiliary Source
’ should be set to
1 = Velocity . The auxiliary display
will then alternate between displaying the flow units and the current flow
velocity. Please note that the instantaneous flow velocity cannot be
displayed in the auxiliary display when the re-settable totaliser is
selected.
10. If no further changes are required, return to run mode and after a short
time the flow readings from the
MicroFlow will be displayed on the
FlowCERT screen.
