Remb0 : if i ordre your module, what else do i need (apart from a ip and a piface) ?
Does it work the same than the previous one ? Is it the same electrical schematic ?
On the module i have found (gobotics), i understand that it is in fact an IR sensor. Is it the case ?
Analog and Digital output. $1.75 = € 1,27 including shipping.
Yes these TCRT5000 sensors work very well (glued on my powermeter and also gasmeter).
But i bought some other type for my watermeter. (The one that is mentioned here =>http://www.domoticz.com/wiki/PiFace)
Cause i doubt this TCRT5000 sensor will work foolproof for long time when it is in a humid area under the floor where my watermeter is.
Ok i understand that nothing has to be soldered. Good point. Now second one : how do you fix it to the water meter ? And 3rd one : is the electrical schematic the same the above ?

I will use Heatshrink (Krimpkous) to safe it. Only the LED’s not

Still then... when the glass is moist the IR light will dissipate and the sensor couldn't work properly <= Did not test this so maybe just in theory.

Yes, It can work because on your 8 outputs are normally 3.9 Volt between the Input Block (0V-GND) and de Output Block (5V) You can’t use that Output port anymore for something else. I rather choose for the 5V on the Output Block.
@bizziebis
I use a large hose clamp to fix my sensor (but my solution senses the half moon with lowcost proximity sensor: proved to be very reliable). But my fixing method could also be used to put your type of sensor at an angle. See pictures and more details in wiki http://www.domoticz.com/wiki/PiFace paragraph "Water Meter Sensor".
