I'm using a Koolance CTR-SPD24X2 Dual 24V Pump Controller to control two Koolance PMP-450S in serial.
With the CTR dials @ ~85% I'm hitting ~104 gal/h according to my AQ5 Pro and AC High Flow Sensor. I did not manually calibrate the sensor. From what I've read my flow rate appears "low." However, I do have a fairly restrictive loop (e.g., lots of QDCs and the RP-452X2 in serial).
Room ambient temp. is ~25C. CPU idle (in BIOS) temp. is ~27C. RAD IN/OUT temps. are ~28C.
How am I doing? Thoughts?
