5.4.3 "Totalizer configuration" menu (if enabled)
1) Activation and counting direction
For each of the totalizers, the possible modes are:
•
OFF : totalizer not enabled,
•
+ : totalling of the positive flows, in other words going from the upstream probes to the downstream
probes (see the wiring of the probes),
•
– : totalling of the negative flows, in other words going from the downstream probes to the
upstream probes,
•
± : totalling of all flows, whatever the direction.
Note: In addition to flow totalling, other magnitudes from the function engine may be totalled if this is
enabled. Contact Ultraflux for further details on this option.
2) Pulse unit and weight
Each activated totalizer emits an incrementation pulse (which can be returned on a relay output; see section
5.4.4 - point 5) each time that the Pulse weight x Unit volume flows in the metering direction of the
totalizer.
The possible units include (but are not limited to): 1ml, 1l, 1m3, 1000m3, 1Gal, 1Bbl…
3) Resetting a totalizer (if authorised)
Resetting totalizers is inhibited when the flow meter leaves the factory. On request and before shipping, it is
possible to authorise the resetting of totalizers.
On site, only an Ultraflux operative will be able to reset the totalizers.
To reset a totalizer (if authorised):
1. Switch to measurement mode (long press on the Fn key) on the page of the totalizer concerned,
2. Press the A key until the totalizer that you wish to reset is displayed on the right,
3. Press the B key to reset the totalizer. A negative image of the pop-up menu is then displayed.
