Hello,
Our regulations include the following statement:
When you look at the DIN/VDI standards regarding branch lines, the external water tap must be connected directly to a ring main (otherwise there is a risk of contamination). Consequently, a water meter could theoretically not be installed in the line as suggested.
Here is my idea: I will install the water meter (frost-proof version) on the frost-proof pipe section coming from the wall (which actually serves as the external water tap) and attach another water tap behind the meter, declaring this as the external water tap. The whole setup is enclosed in a large wooden box.
Do you think this could work? According to the authorities, no one really wants to inspect it; I just need to report the meter reading every year. The water association, which reads the main meter, has nothing to do with the authorities.

The sub-meter must be permanently installed in the water line or pipe leading to the external water tap.

So, there is enough space indoors to install a water meter before the line goes outside.

The ring main runs up directly to the faucet, which goes completely through the wall. Everything else is basically not allowed, as it would be a dead-end pipe without long-term use.
Furthermore, the pipe runs through the living room and it would probably look quite odd if a meter were sticking out next to the cabinet. I have now installed the meter outside and am registering it as such. The meter is frost-resistant and therefore tamper-resistant. Of course, someone could still steal it. According to the authorities, no one comes to check; in many other districts this is also permitted (because otherwise, according to VDI/DIN/guidelines, it would not be allowed at all – dead-end pipe...).

I know of two options.
The better one is to connect the outdoor water faucet to the ring/main supply line. The connection is made via a T-piece on the ring, followed by the meter, and then the faucet. However, this should have been planned in advance, which was probably missed in this case.
As far as I know, a branch line is also possible, but then it can no longer be considered a drinking water outlet. For those who are strict about regulations, a sign can be attached to the faucet outside. The line should also be kept as short as possible.
