Is this the appropriate way to assemble the optical level?
Thank you.

Yup.
I had the same question when assembling mine.

Thank you doggydoc and nick.
Where does the sensor "sees" the water, any part of the sensor or the pointed tip?

The pointed tip.

No, it's not wrong. The older optical sensor is mounted vertically. The new one which is picture above is meant to be mounted horizontally.

Sorry, I wasn't aware of any change. How can you tell the difference between the old and the new?

you wont see an old one unless you purchased one 2 years ago and by now you likely will have updated.
The optical lense is black and crystal shaped on the version circulated for the past 2 years
If memory is corrrect the old style was the exact same sensor used in Airbus toilet overlow warning, may explain why those darn toilets stink!
The latest ones are German built and highly reliable, we have not seen a single failure in two years

It has to do with the last drop of water that stay at the tip of the sensor when the water level goes down. The water drop can stay on the tip if it's vertically mount. Therefore, can lead to inaccurate water level reading. Mounting it horizontally will not have this issue since the tip is NOT the last thing the water see and no water droplet can stay on the tip.

The one I have looks identical to the model used by Tunze. I've had it running vertically since Mar 2010 and I have not had any problems.

That makes sense and thank you for the explanation. I may have to try running it horizontally but it just looks wrong with the wire looping like that and in the water. Oh well at least it's in the sump and it doesn't need to look pretty.

I used to run tunze as well and it was mounted vertically and saw no issue. However, the internal sensor and the properties of the sensor is different. If you mount the new GHL sensor and see no issue then it would be okay. But the manufacturer recommended to mount the sensor horizontally.
I am running my, mounted vertically and have np at all.
If the sensor is mounted vertically and you completely submerge them, then you might have false trigger till the sensor stop dripping on itself, this could be fixed by adding a delay on the timer trigger alarm.
The way I have my sensor setup this will never happen, but could be different on your setup.
