5.4.7 "Totalizer settings" menu (if activated)
1) Activation and direction of metering
For each of the totalizers, the possible modes are:
 OFF: totalizer not activated,
 + : totalization of the positive flows, in other words going from the upstream probes to the
downstream probes (see the wiring of the probes),
 – : totalization of the negative flows, in other words going from the downstream probes to the
upstream probes,
 ±: totalization of all flows, whatever the direction.
Note: In addition to flow rate totalization, other magnitudes from the function engine can be totalized if this
is activated. Contact Ultraflux for further details.
2) Pulse unit and weight
Each activated totalizer emits an incrementation pulse (which can be returned on a relay output, see part
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 are (non-exhaustive list): 1 ml, 1 l, 1 m³, 1,000 m³, 1 Gal, 1 Bbl, etc.
3) Resetting a totalizer (if authorised)
When it leaves the factory, totalizer reset is blocked. This feature enables the totalizer to be used as a
tamper-proof meter and can therefore be used for internal billing (mutually agreed by both parties).
Upon request and before dispatch, totalizer reset can be authorised.
On site, only an Ultraflux representative will be able to reset the totalizers.
To reset a totalizer (if authorised):
1. Switch to measurement mode (press and hold 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.
