totalizer.
Standard = For the standard totalizer function, the counting
pulse for forward and reverse flow is registered on two separate
totalizers. If Forward is selected as flow direction, only the
forwards totalizer counts.
Diff. totalizer = For differential count, a shared totalizer is used
for both flow directions. For the forward flow direction, the
pulses are added, for the reverse flow direction, they are
subtracted. If the totalizer count is negative, i.e. the reverse flow
amount is greater than the forward flow amount, the direction
indicator on the display changes from “F” to “R”. The pulse
output (active or passive) is not affected by this setting.

Overflow totalizer max. 65535. 1 overflow = pulse totalizer
9,999,999 units. Resets the display status and increments the
overflow counter by one. Overflow example:
Overflow 012 12 x 10,000,000 units = 120,000,000 units + 23,455
current totalizer value results in a total of 120,023,455 units
