ᐅ Can someone help identify my in-wall water meter?

Hello @ all,
I have purchased an apartment in Biel that includes a built-in (concealed) box with a shut-off valve and probably a built-in water meter.
So far, no plumber has been able to tell me which manufacturer might produce a meter that fits. The installation date is likely from the 1990s.
It is not a currently common manufacturer.
The shut-off valve is located at the lower part, and I removed the cartridge through the upper opening.
As far as I can see, the thread diameter is 45mm (1.77 inches) and it is a fine thread.
Thank you very much.

That's strange that the plumber isn't familiar with this. This water meter has been in use for several years, but it’s not that old. The best option will probably be to remove it. However, the landlord will have to arrange that.

Hi,

If no one is familiar with this, then just remove it and replace it with a new water meter. I believe there is no way around that.

That will be outdated, and the younger plumbers probably won’t be familiar with it anymore. At most, you can consult an experienced journeyman plumber, if one is available.

Simply remove and replace it; that is the best solution.

Or contact the water utility company. They have archives with their old materials. Maybe they have this water meter or something similar stored in their archive.

He bought the apartment, so he is responsible for arranging the replacement. I don’t think anyone is familiar with that part. I wouldn’t guess either; I would just have the replacement done.
