5.2.2 Totalized Value Display and Totalization Counter
Function
The totalization result can be displayed with a totalized value or a totalized value which is scaled
with the conversion factor (totalized count value). When the totalized value is scaled with the
conversion factor, a specific flow rate is totalized in 1-count increments, which can be used as a
totalizer counter.
The totalized value can be displayed and configured with the following parameters.
