Testing configuration and results
- Pump: Aquastream XT ULTRA
- Tubing: Tygon 3603 ID1/2" OD3/4"
- Data acquisition devices: Aquaero USB 4.0, T-Balancer bigNG, Koolance INS-FM17 readings were monitored by EVEREST v5.30
- Two 10 litre canisters
Testing methodology:
Flow sensors were installed in the loop in series in a horizontal position. Data was collected twice — in the beginning and in the end of test. Then calculated average value was compared to the reference value.
Three most common values were selected. Tests were repeated three times for each measurement point. Testing results:
Koolance INS-FM17 slightly overrates data compared to reference flow meter rate. On the other hand GMR Brass G1/2 flow meter — significantly underrates flow meter rate. However, data provided by Aqua Computer Flow sensor "high flow" G1/4 nearly coincides with reference flow rate values. Reading tolerance of flow meters:
| Tolerance, % | |||
|---|---|---|---|
| Measurement point | Koolance INS-FM17 | GMR AFS1-B Messing | AC Flow sensor "high flow" |
| 2.5 l/min | 9.37 | -8.34 | 3.32 |
| 3.33 l/min | 6.20 | -7.64 | -1.05 |
| 4.17 l/min | 3.96 | -5.29 | -0.38 |
For flow rate accuracy Aqua Computer Flow sensor "high flow" G1/4 receives «Editor’s choice» award:
Koolance INS-FM17 flow meter that don’t need any data acquisition device receives «Recommended» award:
My Koolance flow meter melted placed at the end of the loop after my 2 ATI 4870×2. It can’t handle heat!!
What exactly do you mean by saying that your flow meter “melted”?
Can you describe it in details?

any Koolance product that has acrylic in it is JUNK; too thin, poor quality.

Hallo,
I own a computer Water Flow sensor “High Flow G1 / 4, which I connected on a 5 Aquaero XT, but I see no value. I checked the contacts but it is entirely correct. Can you help?
Thanks
Sorry, but we don’t have an Aquaero 5 at our lab yet.
Hi!
I just bought one of the Aquacomputer High Flow sensors, however there is a distinct clicking noise coming from the device, it’s almost completely silent when running at 1,8L/Min (30%PWM), the clicking starts being audible at around 2,4L/min and increases drastically with flows above this. Max flow I get while using my MCP35x pump i 6,7L/min.
It is even so that the vibration traveling through the tubing to the radiators making a resonating humming sound when the radiator is installed in the case.
I have bled the whole system properly, so I don’t think that air is the problem. I’m wondering if you had any problems with your test-sensor?
