On startup, the unit reads up to 30 l/h
Zitat von »Flow sensor high flow G1/4 for aquaero«
The sensor is accurate up from approximately 40 l/h up to 1500 l/h

That is way below flow rate you should be getting.
If your pump shows that is running at 4800RPM I wouldn't think that there is anything wrong with your wiring, unless if you try to adjust the pumps speed say via-voltage just for the purpose of test and the RPM it's not changing then I would suspect something its up with connections.
I don't know if your blocks are clear and you can see it through, unless there is a blockage of any kind or perhaps there is something abstracting the paddle wheel of the USB flow meter itself from spinning freely I would look into that. Another thing could be your pumps impeller itself but to be honest, that one is a long shot. With your pump running at that speed which is MAX, even with big loop and thick Pastel, you should be getting close to 100l/h at least.....
I would check the wheel paddle first then the blocks
On startup, the unit reads up to 30 l/h
Your best flow rate, 30 l/h, is a very low flow rate. You are running below the flow sensor's specifications. I would not trust those result.
You may need a second pump. And yes, pastels can be pretty, but they generally gunk up over time.

Simple way to test for the paddle issue is and you will know this right away, when you have your meter out look into inner-out thread and just blow gently air into it, the wheal should spin for few seconds but make sure inside is dry, if it spins its all good, if it stops dead or seems like it has hard time spinning consistently right after you blow the air then there is problem with the wheal.
TBh. you shouldn't need second pump, you can have it if you have huge system and need for bleeding purpose, or for redundancy, but not for the sake of increasing flow rate from 30l/h upward, single pump should push that with eaz
I took it apart but left it connected to the loop. The wheel appears to spin fine. On testing I noticed that the flow goes up to 16 l/h when horizontal, but only horizontal.
