Operating instructions for turbine flow meter

5.1.2 Resetting the resettable total volume (RESET TOTAL)
You can reset the resettable total only if you have reset the
register of the partial volumes before. To reset the resettable total:
press RESET for several seconds. The display will show the words
RESET TOTAL (see fig.):
You must carry out the following steps (in this order):
1. Wait until the display is back to default standby mode (i.e.
showing only TOTAL).
2. Press RESET shortly.
3. The meter will now start resetting the partial volume register.
4. While the display shows all segments, press and release the
reset button.
5. The display will show all the segments again. Only then follows
the phase where all segments are switched off.
Finally, there will be a display showing the total that has been
reset (RESET TOTAL).
5.2 Output of liquid with display of current flow rate (Flow Rate Mode)
It is possible to output a liquid and have the following displays available:
Partial volumes having been output
■ ■
Current flow rate (Flow Rate) in [unit of partial volume per min.], as shown below.
■ ■
This is how you get into this mode:
Wait until the meter is in default standby mode (i.e. the display shows only the total volume).
■ ■
Press TOTAL shortly.
■ ■
Start output operation.
■ ■
The display of the current flow rate will be updated every 0.7 secs. For that reason the display may ‚flutter‘
somewhat with low flow rates. However, the higher the flow rate, the more stable the display will be.
Tip
The current flow rate will be shown in the unit set for the partial volume register. That means if
partial and total volume have been set to different units (as shown in the example below) you
must bear in mind that the flow rate shown is in the unit set for partial volumes. In the example
shown, the flow rate is in QTS./min.
The word GAL next to the flow rate refers to the register of the (resettable and NON-resettable) total
volumes which will be displayed again as soon as you leave the ‚current flow rate‘ display mode.
In order to go back to the default standby mode, press the TOTAL button again.
Accidental pressing of the RESET or TOTAL button does not have any effect in this state.
