And the most important detail (I hope I can explain this correctly, I don't know much English):

- The flow is in the same direction as the probe slot. I attach an image, but if you have any doubt please ask me. In the next two days I am going to watch it to confirm if I'm right.

I solved my problem in a similar way - I direct my main return flow from the display tank to hit the probe – it works great now for more than a month
