I have long been annoyed about the treasures in the water circuit, because an exact measurement of the flow and the impairment of the same by components such as radiators, quick connectors and other brakes was not possible until now and the dispersion on the other hand was so enormous. , that I preferred not to take such measurements and their results. Well, so to this day. With the Keyence FD-Q10C on a piece of 1/4" tube (hose definitely goes wrong and becomes too inaccurate) I am now really well equipped.
The operational possibilities are almost unlimited, now only a test setup has to be made to have water circuits with 20 to 200 l/h, then it can finally start. What I have been able to measure with the usual suspects so far has not been really consistent even within a series of measurements. Only air bubbles can of course tarnish the fun a bit, but that's why things are currently at the lowest point.
By the way, the measuring principle relies on ultrasonic pulses, so it is non-contact, because the flow meter sits on the outside of the tube and has no direct contact with the liquid. This works quite neatly on such a smooth tube from the hardtubing set, because it is smooth and not grooved. I'm looking forward to the first tests, so I'm sure I'll come up with something nice 🙂
