I believe the "Import calibration data" option allows you to import an external file that is used to calibrate the device.
The default, though perhaps not absolutely accurate, is probably sufficient to show change, which is what I would be interested in.
Your hose/fitting size are adjusted for by using the included "Diffuser Plate".
From the manual: [attach]7132[/attach]
I guess what I was getting at was when you initially setup the flow meter you can pick the fitting size etc etc. After removing the flow meter and powering off the system and then powering back on with it still removed and then removing it from the software. Powering down then connecting it back when you open the software the option to configure it does not show up.
At any rate I just installed the "high flow usb" flow sensor since this sensor should give me very accurate results without having to fiddle with a raw value/actual value and I have some interesting data now which tells me I may be at the limit of the D5 pump or a CPU block may be too restrictive.
60% PWM speed= 45 l/hr
65% PWM speed= 62 l/hr
70% PWM speed= 78 l/hr
75% PWM speed= 96 l/hr
80% PWM speed= 115 l/hr
85% PWM speed= 134 l/hr
90% PWM speed= 156 l/hr
95% PWM speed= 190 l/hr
100% PWM speed= 240 l/hr
My setup Consists of
CPU and GPU block.
3 360mm Radiators (30mm/45mm/54mm).
EK D5 Gen 2 Pump in a Singularity Computers Protium Reservoir.
I can't tell what RPM the pump is running as the RPM pickup stopped working and EK is making it difficult for me to get it replaced even though it's still under warranty
As of right now to stay around the .8-1gpm range it looks like I will need to run the pump around 94% PWM.
I am leaning towards maybe a restrictive CPU block perhaps, Loop is perfectly clean too.
