Actually, you need to calculate the rate of change of the VOLUME.
Characterize your tank for volume (gallons, etc) versus level. Then
calculate rate of change of the volume. The difference between the
outflow rate and the tank volume change is the inflow rate.

Subject: [foxboro] Math question
hi list,
Fun question for you all :
Let's imagine a tank which is filled by the top and drained by the
bottom.
I have a level indicator on the tank (LI0101) and a flowmeter on the
drainage pipe (FI0101) and i add a accumulator on it FI0101_A.
How can i calculate every 10 minutes, the inlet flow ? I need a
mathematic
formula of course.
Thank you all, it 's important.
