Flow readings are calculated by the MultiRanger Plus as a function of the head under
the transducer, installed upstream from the primary measuring device ( P-40 ). The
flows are then accumulated in the arbitrary volume units chosen per the time units of
P-41 in an 8 digit totalizer. In the event of a loss of echo, the totalizer will continue
being incremented by the flowrate established from the last valid echo. The totalizer
will stop being incremented and hold its last updated value when in the program mode
or if the fail-safe timer expires ( "LOE" is displayed ).
The totalizer contents are stored in RAM and will be lost in the event of a power
failure. However, after every 1 hour of continuous operation, the totalizer contents are
stored in the EEPROM. Thus, after a power failure, the totalizer will be loaded with
the last value stored. Once the totalizer has been filled ( 99999999 ) it will
automatically reset itself to zero and resume totalling.
The MulitRanger Plus can be programmed ( P-39 ) to normally display one of the
following readings :
» enter option "0", hold last reading selected in run mode
» enter option "1", high total: 4 highest digits of the 8 digit totalizer
» enter option "2", low total: 4 lowest digits of the 8 digit totalizer
» enter option "3", head
» enter option "4", flow
It must be noted that only half of the totalizer digits
can be accessed or viewed at one time.
e.g.
high total low total
P-54 P-55
8 digit total
1325 4769
To momentarily view an alternate reading while in run mode and P-39 ≠ 0, press the
desired programmer key ( "READ" is not applicable to OCM ).
e.g.
normal display is high total, P-39 = 1
low total is momentarily displayed
normal display of the
high total returns
If P-39 = 0, alternate readings cannot be momentarily displayed. Pressing the desired
key will change the display and hold it there until the next alternate reading is selected.
