Hi,
I'm trying to install sensor on gas meter BK-G4M but can't figure out what is the right position. Meter looks exactly like the one mentioned in the shop (BK-G4) but with letter M on it too.
Sensor is working , I can simulate pulses with magnet . But I can't install the sensor on the meter to get any readings. Any suggestions ?
thanks a lot
Corresponding to the spec (see http://docuthek.kromschroeder.com/doclib/main.php?language=2&folderid=40...) the magnet should be located on the second decimal place (1 imp per 0,01m^3); thus, there should be a cavity underneath this decimal roll to place the reed switch... Does the type label tell the impulse rate?
See http://docuthek.kromschroeder.com/doclib/main.php?language=2&folderid=40... for the original pulse sensor spec...
Impulse rate is 1 pulse 0.01m^3 it's exactly like one on the shop picture
But I tried any places in this cavity and still nothing.
Problem is that you can't put sensor equally positioned in the cavity because cavity is a bit rounded.
I thought somebody might know a trick to how place it right:)
The probe's laser marks should face upwards. For maximum sensitivity, the probe should be pulled to the front right inside the cavity and pushed upwards as deep as possible. Don't worry about the bent cable, it will not be damaged, only a bit dented.
Some people also managed to get a reading by attaching the probe to the glass, right in front of the last digit.
I tried at the bottom no luck what so ever
I would try glass. Good idea.
Did you try with a compass if there is a magnet at all?!
Yes I tried
Even my phone can detect a magnet there
I put it on the glass now . Would wait a bit and see what would happened.
If it doesn't work , the only option is to wait for optical sensor :)
BTW does polarity make any difference ? I have now red connected to + .
Since it's a mechanical switch, polarity shouldn't make a difference. For pure aesthetic reasons, you might wish to keep the red wire connected to the +.
To test the FLM's pulse port you can just short the + and - and refresh the syslog page in the local web interface. You should then see some pulse entries in the syslog.
I tried that already
with shorting +&- and puting magnet close to the sensors
both cases I have reading
but not from the meter. Looks like magnet there is not strong enough
I use always a normal reed contact pushed in a plastic foam ... had some problems with the flukso sensor
Today I received the FLS02-F1, sadly it is not working when installed as described. Also not in front of the window.
Can you send a close-up photo of the installation via the contact form?
BK-G4M is most probably without usable pulse output. That's what an extra M makes. Unfortunately for some reason some gas distributor companies order this model from Elster instead of the BK-G4 or BK-G4T (temperature compensated for outdoor use)
Very bad news then. I've just received my flukso last week and I am struggling with the same issue. Does anyone have a solution ?
Same problem over here. Maybe some optical reading is possible?
Problem is that there is no optical reader available yet from flukso . If you handy enough to build one you should be good to go . There is a marker on this meter
Hi SEM. What do you mean by marker ?
I saw that they are working on an optical sensor. See end of the post;

I cross my fingers ;-)
Marker is metal plate for optical sensor
it is present on the meter
For the post you send it's 1 year old . Still nothing yet
I have a BK-G4M and got the sensor to work properly after attaching it to the glass. The following picture shows how I positioned it: https://drive.google.com/file/d/0B23xcuwvvtOGdTFLOVp6b1Z6bjQ/edit?usp=sh... I hope this fixes it for you!
Interesting
I tried it about a year ago without any luck . Would try again .
What did you use to mount ? gum ?
It's the famous 'Patafix'. See over here: https://www.flukso.net/content/simple-method-mounting-fluksometer
Indeed "UHU Patafix" or in my case "Pritt Poster Buddies" which appears to be identical, see http://www.prittworld.be/nl/Consumer/Ouders/products/fixing-multi-tack.html. The gas company recently came to note down the readings of the meter and it was very easy to detach & put back on. I also used it to attach the Fluksometer to the wall - great suggestion by jgysenbergs.
STFNVRMLN - Thanks a lot!
I starting to get readings
would test more and see how reliable they are.
Looks like signal is very weak . Few mm left or right and I don't have anything
Still working great. I think this one is cracked.
If only we could find the way to read from this water sensor :) https://www.flukso.net/content/elster-water-meter-v200
Please note that it's okay to push the FLS02-F1 all the way into the cavity. Don't worry about the probe's cable being bent. Just push it all the way in with the markings facing upwards and the probe as close to the front of the cavity as possible. The probe should be almost horizontal. If it's sticking out, the distance to the magnet increases and thus the possibility of no pulses being generated.
I tried all the places in the cavity . No luck at all
on the screen it works perfect!
I also placed the sensor on the screen and it starts reading. Is 1 pulse = 0.01m^3?
Kind regards
Yes, 1 pulse is 0.01m^3. The constant of the sensor should be set to 10 to get consumption in liter.
@stfnvrmln, thanks for the information...
