Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Stored volume = capacity × level increase. Source volume = stored volume ÷ fill efficiency. Fill time = source volume ÷ source flow.
FAQ
Tank Fill Time Calculator questions
Why can source volume exceed stored volume?+
Entered losses represent water that does not remain in the tank because of flushing, leakage or process loss.
Can flow rate change during filling?+
Yes. Pressure and pump operation can make the actual rate vary over time.
Does this prevent tank overflow?+
No. Use appropriate level controls, overflow paths and supervision.
