RFXMeter with RFXPwr + RFXPulse

[j.hoekstra]

I'm thinking about getting the above combination with the discount-code provided, but have some questions of a practical nature.
The RFXPwr needs to be connected to the phase-wire and my knowledge of the colours used in std installation is a bit rusty.

First I like to verify this is a 1-phase installation and second I'd like to know if the red wire is the 'hot' wire. Is there anyone who can tell me?
For the gas and the watermeter I'd like to get the RFXPulse(2x) the watermeter has a little metal disc at the right hand bottomside which turns for every dm3 I think:
http://home.student.utwente.nl/j.p.hoek ... C00768.JPG can I place the Reflective-Optical sensor(70091) to count the waterusage on this?
The gasmeter is said to have a little mirror which can be used to count gasusage using the same reflective-optical sensor, I couldn't really determine where that would be on my gasmeter. I don't really 'see' a reflection or mirror on the last digit 6. Does someone have the same gasmeter as me? And does it have a mirror?

The green wire is the "hot"
As you can see it is connected to the brown wire.
Brown is "hot" and blue is neutral.

It is possible that you have no mirror on the gasmeter.
There is a post on the forum from a member that also had no mirror.
Then you must ask for a new meter.
