4.3.2. Display Appearance
Decrease Total for -ve flow:
The meter will not register
negative flow on its outputs unless this box is checked.
For reverse flow the rate will show a “
-
”
sign before the rate
and the total will be reduced accordingly.
One of the transistor outputs (PNP or NPN on Pin 6 or 7)
are configurable to give a logic level when reverse flow is
detected.
Once selected, the totaliser will adjust with the negative flow
and the NPN and PNP outputs will give a pulse output in
proportion to reverse flow seen.
The analog pins will give an output if scaled appropriately.
