Need advice on Water tank level monitoring

I used a Shelly Uni.

I used ADS1115

Yea sweet I thought so. Ill give it a crack

So I got one of these, wired it up and it is all good to go. The only this, how on earth do I mount this thing?

The thread is like 12mm, my pip from the low end of the Tank is like 40mm. So I need some kind of 40 mm T with a female 12mm thread?

Anyone done this?

thanks alot

i have connected the pressure sensor and the green line also to gnd line shelly uni plus . and its working well more accurate than taking off the green line.

what i want to connect also the temperature sensor and the green line is used for pressure sensor . how can we do it . both together

please advice
