Gas meter GMT GT4 works with gas probe

This meter works fine with the gas probe.
You have to remove the plastic cap first.

Great! What's the orientation of the gas probe within the meter's cavity. Are the probe's Flukso markings facing up or down?

I think it both works. It even fits perfect.

The difficult part is removing the plastic.
I didn't find a way without breaking it.
The plastic doesn't has any function.

For further reference: I had success only by putting the text side up.

Indeed you have to irreversibly open the cavity. I reccomend cutting the bottom of the cavity length-wise.

There was an additional placeholder in my meter, that came out easily by pressing the sides (or pulling with pliers.

Hi Joris,

What do you mean by: "There was an additional placeholder in my meter, that came out easily by pressing the sides (or pulling with pliers)." Was this inside the cavity?
Also what do you think is the best tool to cut it nicely? I would like to glue the plastic cap back on if possible.

Hi,

The "placeholder" was a H-shaped piece of plastic that was clamped by little lips to the side of the cavity, inside the cavity. This was sealed in, so invisible from the outside and seemingly without function - in any case irrelevant to the functioning of the meter or later re-sealing.

I tried carefully to remove the plastic cap but I accidentally ended up destroying it. I imagine it is possible to remove cleanly, but some prior experience would help, the material was 40 years old in my case.

In any case it is cosmetic only (the resulting cavity is still sealed from the rest of the meter), barely noticeably (it's facing down and a clean cut hole there could be mistaken for a design feature).
If I had to, I could probably do a decent job restoring the hole on my meter using some epoxy clay.
