Hi,
I replaced my very old Kent V100 water meter by an Elster v200 device.
I bought a Flukso sensor months ago to measure the v100 water streaming but the magnetic field was too low or non-existent. Since the v100 was 20 years old I replaced it (free of charge) by a v200 Elster.
I believe that, the current v100 Flukso sensor is incompatible with the v200 water meter.
I checked internet (flukso.net as well) and it seems that there are sensor devices for the v200 Elster available. (Cyble sensor ITRON, Elster PR6,...)
Has anybody in the forum experience with Elster V200 water meter and with above mentioned sensors?
Are there other sensors available which could work with a V200 and connect to the pulse port of Flukso?
Any Advise appreciated.
Kr. Marc.

It seems the half-red dial in the lower right has a reflective surface one could point a cheap optical sensor to. It has to turn fast enough when consuming water though.
I would also try with an opto sensor as the actual detection seems not trivial - see http://www.eurooriental.com/schlumberger/cyble.pdf on how this works; I could imagine something with a triggered coil that emits a magnetic field that is "read" for changes in the magnetic flow when the target passes under it, but...

Hi,
Elster V200,... has a watersensor (PR6) which fit very nicely to the water meter.
I checked the connection and I feel a need for some more information how to connect it to a Flukso pulse port. (+ and -). !! Pulses are active low !!
CH1P=Both forward and reverse direction pulses are output here
CH1D=Direction flag (High => forward flow)
CH2P=Forward flow minus reverse flow. Compensate backflow
CH2C=Reverse flow compensation flag. Low while backflow compensation in progress
TAMP=Activates when the pulse unit is removed from the meter. Also=battery low
GND=common
Can some help here?

I live in Euroipe, Belgium.
See http://www.johnsonvalves.co.uk/Data/Data%20Sheet%20No.%2001.12.01%20-%20... - CH1P or CH2P >> (+), GND >> (-)
Hi,
Thanks for the clear Elster PR6 connection document.
Is it correct by saying that yellow and black is the best connection to Flukso pulse port (+ -) versus red and black?

In Europe there should be no difference as it is not allowed to feed water back; thus reverse direction should not occur...
I continue testing the Elster (Falcon) PR6 meter.
This device is integrated with the watermeter itself. It physically replaces the counter lid.
I connect CH1P yellow wire to - port on the Flukso and COMMON wire to + port.
I leave all other wires disconnected.
Flukso shows me a flat 0 graph line. I measured the voltage between CH1P yellow and COMMON black.
I read 0.509 0.510 0.509 0.510 V ...
I don't understand why it always stays at above listed values.
I have one remark. When I received the PR6 I had to remove a small red-silver foil.
Unther the foil there is a plastic circle plate integrated with the rest of the device.
Probably it's blocking the pulses.
Should I remove this or not?
The PR6 has a builtin 3.3V provider. So, I'm sure (even if there is no led available that internal voltage is coorectly set to 3.3V
Has somebody similar experience with the Elster meter + sensor?
And ... what are the results?
Marc.
Can I be helped?
I guess not...
The pulser is open collector, so it pulses with the FLM supplied power and trying to read some voltage on it is measuring, well... - help yourself on wikipedia, what "open collector" means or g**gle for the cyble specification...
By the way: "red is black and plus is minus" - but to be serious, common/black is ALWAYS (-) in a DC setup..., so YELLOW >> (+), BLACK >> (-)
The 3V3 battery is for the detection circuit only; any connector should be free of any potential (otherwise you'd just fried your FLM)
Just re-read the Schlumberger document - according to that BLACK it not needed at all; if it is like in http://www.eurooriental.com/schlumberger/cyble.pdf then it is YELLOW >> (+) and WHITE >> (-) (if WHITE is missing then it can be assumed (sic) that WHITE === BLACK)
If (WHITE === DIR) then YELLOW still (+) and BLACK to (-) - why do they provide so many different configurations?
Watermeter Elster V200 + Elster PR6 sensor + Flukso v2 is now working fine, guys.
I rectified my stupid connection error (black must be minus, yellow or red => plus; all other wires must be disconnected) and reduced the space between watermeter glass and PR6 to less than a millimeter. I had to increase the pulse/litre from 0.5 to 1.0 (0.5 was required with the old watermeter + flukso sensor).
Thanks a lot, GEBHARDM.
2 small problems are still open:
1) clicking on "DASD", than on "water" gives me a graph with on the y-axe litres/day while I'm sure it is just litres. I adapt it manually each time I consult the graphic.
2) Distance between Flukso meter (now measuring 3 phase 400V + solar panels) is 22 metres.
I should move the cable to a couple of other cables (almost invisible; ceiling) or...
Try to connect sensor and port 5 Flukso by wireless or...
put a 2nd flukso near the water meter.
Any ideas?
Thanks a lot.
