Hello.

We have any reservoir. And it have any movements: filling and draining.

We need to calculate mass of draining for a day.

How we can calculate in pi-system: PE or Totalizer subsystem or AF. And thise values must be stored in PI. We have parametres for mass from sensors.

I would be glad if I found any method to calculate dynamics, but i don know how.

I mean dynamics=M(i2)-M(i1)

?

Hi Ildar,

AF Expression Analysis would be the way that I would choose to perform these calculations. If you have many reservoirs, then AF allows you to define the Analysis as part of the asset template, and of course an AF Analysis can write its results back to a PI Point.
