Reading differential flow rate, total or accumulated total
The returned values are given including the decimals and represent the actual value.
The given value may differ from the value that is shown on the display – this is due to
the fact that the display is limited in the number of digits and may have a slower
update rate set.
For example, when two decimals are selected for total and total has a value of
123456.78 the display will show 23456.78 while communication will read a “total” of
12345678 and a “total decimals” of 2.
* Clearing total
It is possible to clear the total counter by means of writing a value of 0 to all the 3
registers of total/flow rate in a single write action. Writing any other value will result in
the reply of an error message because the registers of total/flow rate are during
operation read-only.
