fxTotalizerRate

Description
The function accumulates a flow rate into a cumulative (eternal) total.
Besides of the cumulative total the function also outputs the flow increment that represents the
increase in flow quantity in the last calculation cycle. This increment value serves as an input for related

Unit of input 'Flow rate.
Unit to be used for total and
increment.
Refer to the next section 'Unit

Changing the unit will only be
possible when the cumulative total
value equals 0.
The cumulative total will be reset to
0 when it reaches the rollover value
Defines the number of decimal
places for the total and increment
output values.

applied)
This should be used with great care!
