Alex, believe it or not, according to my pressure gauge...I only get ~1 ±.2psi with the flow meter @ full flow.

Pump________Total head pressure (PSI)_______Max Flow (l/m)__________RPM's

3.2______________6.2 ±.2____________________~11.2_____________4470 ±30 (with a very small spike to 4530-4560 when full restriction was applied)

Your higher RPM's may be due to a higher amp rail PSU than what my PSU is. When I did the video I linked earlier in the topic...I had used a 550W Antec NeoHE with a bad 5V rail, I later tested the 3.2 with a much lower watt PSU (220W Shuttle unit) and the RPM's dropped by 1k.




I also tried to test my INS-FM15 (predecessor to the INS-FM16) as well but I was forced to toss all those numbers out. It appears the damn thing is borked as it doesn't want to read flow higher than 9999 mL/m for some reason, it just reverts back to 1000+, and tops out @ something like 1054. The specs I have that came with it show .5-15 LPM (similar to the FM17) so even if I'm supposed to add 1054 to 9999, it still doesn't = 15 LPM.
