When people are talking about flow meter accuracy I like to steer them to this Igor's Lab Review of the Aquacomputer High Flow verses the Thermaltake TF1 verses the Barrowch FBFT03 verses a Keyence FD-Q10C high precision flow meter. Spoiler Alert - The Aquacomputer High Flow matches the Keyence FD-Q10C high precision flow meter almost perfectly while the Thermaltake and Barrowch were so bad that you might as well not bother looking at them. The Thermaltake readings are consistently way too low while the Barrowch starts out too low then quickly changes to way too high. They are both so far off that the author of the review said, "the deviations of both flow sensors (Thermaltake and Barrowch) are so extreme that they simply should not be used".

The original article is in German and the English translation is a little rough but understandable. The Barrowch FBFT03 shows up in a lot of custom loop builds and the owners sometimes get mad when I show them this article. No one likes to find out the flow meter they bought is totally inaccurate. I would never consider buying a flow meter from anywhere other than Aquacomputer. Kudos on another great product.
the high flow NEXT is the tested one ;-)
the NEXT is better. The NEXT sensor corrects the flowwith a no linerar correction in every flow range.(act values: 70.8l/h for the HF, 75.5l/h for the HFN). Above one is for HF and the below one is for the HFN. Flow ist held at 75l/h. Which one should I trust now more?

The HFN is very linear, especially in the lower range (<100 l/h) where there are otherwise larger deviations.
