What is your "setup"? What special "technical documentation" do you request for a reed switch? The mechanical measures? The specialty is the housing which fits into the cavity of the named gas meters, as shown in the pictures; rest can be obtained by an "educated G**gle search"; one click showed the original Actaris part number ACTARIS 951-858-06 08 30/1004. Just try with a simple reed contact first and also check the manual on compatibility and all the other yet unasked questions.

I actually did all those things :) . I got an Elster BK-G6 M gas meter and when using a smartphone app to measure the presence of the magnetic field I can see a slight change when the meter is working. Also the documationation from Elster claims there a pulse should be detected. Yet when I place a reed switch, which I had lying around, I don't seem to get it triggered. The reed swicht itself works fine as I can trigger it with a magnet. So I wondered if the flukso probes had, I don't know, something which I don't seem to understand. Already tried placing it on the numbers, in the opening under the rotating numbers etc. Want to make sure that if I buy the probe it'll work.

You actually have to place the reed switch "very deep" within the cavity to get a proper reading (utilities call this "tamper proof"); and it should be along the actual wheel that contains the magnet - see https://www.flukso.net/content/no-readings-gas-probe

I can confirm that the sensor works with an Elster BK-G6 M. (i have the same setup). It's not the easiest sensor to get working properly though, due to the different size of the official reed switch and the flukso one.
Important details to keep in mind:
* If you use the flukso reed switch, you'll have to place it with the printed side (text) towards the magnet (upwards) in the cavity.
>> the side with the laser etched text was clearly the most sensitive surface. So, that needs to go up against the bottom of the gas meter.
* From my experience, it's best to put the sensor cable on the left side, as that puts the switch in the closest vicinity of the magnet in the Elster BK-G6 M. I think the magnet is near the middle of the cavity but a bit to the right.
* It may be needed to attach some kind of clamp or fixture to make sure the reed-contact stays in the cavity, as deep as possible.. I used a piece of plastic with double-sided tape myself, sticking to the bottom side of the clockwork mechanism.

Left and right from standing in front of the meter?
Thanks for the help everyone, no readings so far.

What does the meter's type label tell? Does your meter contain a magnet at all? (I actually never received one with a magnet from my utility)
IF there is an impulse THEN it must be written on the type label (for example 0.01 m^3/imp); this and only this will indicate where to place an impulse sensor - and this to judge remotely is far too difficult; again, refer to https://www.flukso.net/content/no-readings-gas-probe as this is actually no dev corner issue at all...

I've alsro had trouble with my Metrix 6G4L, which days 1Imp 0.01m³. The Fluksi sensor couldn't reliably work when fitted in the dedicated cavity.
I ended up sticking it on the front with some adhesive tape, and from what I see here http://www.energiesparhaus.at/denkwerkstatt/allgemein_a.asp?Thread=29038 I'm not the first one.
Maybe this could work with yours as well

I've posted it in the dev corner because I'm interested in the AT, hysteresis and what not. Reed switches have characteristics.

@Perponcher:
Left & right indeed, as when standing in front, and facing the gas-meter.
If you can measure a magnetic field disturbance with your smartphone, that means there is a magnet inside, right?

It may not show on your graph for other reasons but put an ohmmeter across wires (disconn from flukso) and see if the switch opens and closes with useage to prove it out.
