Wattage or percentage on controller for pump flow?

[buruskeee]

What do you all think is more accurate it trying to estimate flow rate from a DC pump?

My flow chart shows about 2000GPH at 6ft head pressure on an 85W rated pump.

I have it set to 30% on my pump controller and the output is showing 39W on Apex.

What is more likely the flow rate, the 30% setting on the pump controller implying about 600GPH? Or the 39W implying about 900GPH?

Anyone with a flow meter on Apex want to test it out with their DC pump?

its going to be different for everyone depending on their plumbing

I’m speaking in terms of after plumbing head pressure is calculated - ie we know what max flow is at 100% with plumbing.

Also to keep it as simple as possible, let’s just assume 6ft height of return line with zero turns/elbow (and the measured max flow is 2000gph).

question.
return pump
have a jebao 15000 \105watts\max head 7m
have approx 15.5ft head presure(sump in basement)
giving me approx 660gph
external cpr-1oo overflow
max 900pph
question is im only running my return at 55 watts so Im assuming that gives me approx 330gph,and Im using a durso to reduce the gurgling noise,wouldn't increasing my wattage would that make it worse?
