Water drops in the glass make recognition impossible

[francwalter]

Hello
Just some days ago we got a new but also very old school water meter and only now I installed this great ESP32-Cam system.

But after a day I noticed that a drop entered the inner of the glass and I had to get rid of the first digit. Later there were drops everywhere and now recognition is not working anymore at all.

Can I do something about it?

I already sent an email to the provider to replace the meter because it will be full of water in a while but i doubt that they'll do something about it.

Is this a well known problem?

Thanks. Frank

EDIT: that are not water drops but Air bubbles, I know now. The meter is filled with water. Someone said they disappear after a few months and are caused by the meter change.
EDIT 2: that is wrong, the dops are indeed drops, not air bubbles.

Never heard about this nor have I seen any water meter that had water in it. This defintely is a faulty unit and should get replaced, but yeah, good luck with that

Are they water bubbles that move a little?
Or are the water bubbles fixed and do not move?

In my experience, it is usually a bad installation and not a defective water meter. The bubbles form when the water meter is not filled and installed correctly. The water bubbles then collect at the highest point, which is under the glass. Unfortunately, it is not so easy to remove them in the usual ways. An unorthodox way is to reduce the pressure and loosen the screw connections a little. Then turn the water meter upside down and let the water run for a short time. The water bubbles are then flushed away and the water meter can be turned upside down again, tightened and screwed tight again.

Thanks, I edited my first post, not reading your answers, sorry.

So another user told me, its not water drops but air bubbles in the water, that could happen after installation, I have to wait a few months.
The new water meter is a ES 40-13 from Ebeling und Sohn.
At the moment there are air bubbles on the main digits, it is totally unusable:

The bubbles move every time, when I close a water tap, maybe I could do that a lot of times.
Indeed I could try to move the meter, so the bubbles move up, but I doubt that they wont come again and furthermore, one of the screws is sealed, so I would have to break the seal to make the meter loose.
If I could loosen it, I would fix it at a position with the glass not showing up but sidewise, so the bubbles have to wander to the top, which would be the left side, not interfering with the digits.

But I think I have to wait 😢

The water droplets certainly won't disappear, as the glass is the highest point of the water meter and air is lighter than water :-)
But they can move around a little.

I was right in the beginning, no air bubbles, but water droplets, as I thought.
I just opened the one, unsealed screw nut a little bit, turning the meter a bit sideways, so the bubbles could go up, but then I saw that there is water standing at the bottom of the glass, its not full of water and droplets hanging at the top of it:

It is clear to me now.
I guess the meter is not put the right way or it is not tight enough. Either there should be no water at all in the glass or it should be completely full of water, but like this it does really not look right to me.

In another forum I posted a picture:

The meter is now nearly full of water, I guess in some weeks there are no more drops or bubbles anymore.
At the moment the last air is over the digits, so I have to wait...

Maybe the trick is to turn it upside down, so that the display fills indeed with water?
No more drops of water in water would be then possible anymore 😃
I will try tomorrow, I can turn it a bit so I should be able to turn it half way.

The man who installed it answered in a mail yesterday that this can happen, that there are water in it, but it doesn't effect counting.
So no help from this side, I need to help myself 😉
