total calculation of an irregular weight descent

hi everyone, would it be possible to know the sum of these weight descents by calculation?
I tried several calculations but using either the tagval or the tagmax-tagmin I didn't get the result.
this weight increases from time to time (as shown in the photo) consequently the calculation is not successful, assuming wrong calculations.
I need a calculation that totals this weight, in this certain time.
the hourly flow I can calculate it, but the total no!
considering that the flow is not constant and therefore today can have a number, and tomorrow another, I need to totalize all these descents in weight.
I use pi processbook 2014

thank you for your precious collaboration.
