In case of a malfunction of a dosing pump, the user will have to dose manually until the repair.

So, it could be great to know the operation hours for dosing pump in a specific period of tme (one day, one week, one month what ever) so as to be more easily to calculate the rate of o manual dosing.

For example, one of my dosing pumps controls the nitratereductor. When reedox comes to a specific value it comes on and then off when reaches another value. So, if dosing pump goes out, I will not know the rate If I have to set the flow.

I think that applies too if a drip system will replace a function of a dosing pump that reacts with program logic.
