Fig. 21-2 Time of day totalising (cycle)
Information concerning the totalising
If the transmitter is disconnected from mains at the time of totalising set, it is not possible to
create or to save a total for the respective day.
If the unit has been shut down temporarily between two totalising points, the flow rate
missed during the inoperative period is not going to be considered for totalising. There will
be no averaging interpolated replacing the lost flow rate.
