3.5 How to Measure Totalised Flows (manually)
The basic measurement indicated on the FLOW READING screen is the instantaneous flow rate, which in
some applications may vary over a period of time. Average flow rates are therefore often required in order to
get a better understanding of an application’s true performance. This is simply achieved by noting the total
flow over a specific period (for example 30-60 minutes) and then calculating the average flow rate over that
period of time.
1. Press the Options key to access the
FLOW READING OPTION screen shown.
2. If the Totaliser is indicating Run, select
it and change it to Stall. Press ENTER.
3. Select Reset +Total and press ENTER.
4. Press ENTER on the subsequent screen to
accept the reset.
5. Press ENTER again to return to the FLOW
READING OPTIONS menu.
6. Select Reset –Total and press ENTER.
7. Press ENTER on the subsequent screen to
accept the reset.
8. Press ENTER again to return to the FLOW
READING OPTIONS menu.
9. Note and record the current time.
10. Select Totaliser and change it to Run.
Press ENTER.
Note: the totalisers begin to count up as soon as Totaliser is set to Run.
