Here on the forum there is a post where someone shows how he inserted the temperature probe into the tubing using a T-fitting:
So I ordered a bunch of T-fittings on Taobao:
However, playing with them and the probe, I’m not sure if it makes sense. If I push the probe all the way in, it will obstruct the flow, plus only the tip will be surrounded by fresh water:
Can this even work? Isn’t it better to put the probe into the tank?
Unless the flow sensor does not trigger, I assume the temperature in the tubing should be very close to that in the tank.
