Gas meter reading
How to take readings from a gas meter?
The ability to automatically take off gas consumption depends on the gas meter, but most modern gas meters already have this technical capability. Moreover, many manufacturers offer a separate option "pulse sensor", for everyone it is different both in cost and in functionality, only the price is always high, and it is not clear what to do with it.
In fact, everything is simple, in many gas meters in the low order a magnet is built in, which, together with a reed switch or a "hall sensor", generates pulses, which are necessary for the possibility of automatically accounting for gas flow.
How to determine if it is possible to take pulses from your gas meter?
You can determine if it is possible to take pulses from your gas meter by studying the documentation for your meter model or visually, and then experimentally.
Visually:
Take a close look at the low order of your counter. Often in the number "6" you can notice a metal insert. Look at the counter itself, if under the dial there is a place for installing a module, then most likely this place is just for installing a pulse sensor. Examples in the photo.
Experimentally:
Use the usual reed switch, which can be ordered from us in the store, for example. Connect the tester to the two contacts of the reed switch in the sound indication mode and lean it against the working gas meter, its lowest level, to begin with. Find the place where the pulses appear steadily and stick the reed switch on a regular double-sided tape.
What is one impulse?
Depends on the decimal places on your gas meter. Most often, 1 impulse = 0.01 m3 of gas.
What's next?
If your gas meter is ready to integrate into the monitoring system, then for the final stage you will need a smart-MAC D105 pulse counter More details »
The connection diagram is simple, just connect two wires from the reed switch to the pulse counter and you're done. The smart-MAC D105 pulse counter itself is installed on a DIN rail at a distance of at least 0.8-1 meters from the gas meter, in accordance with the standards for the placement of gas meters.
After connecting, add the device, the pulse counter, to your account on our Dashboard and create a widget indicator or a graph. In the widget settings, select the "multiply" arithmetic operation by 0.01 and set two decimal places. And that's it, now the widget displays the gas flow in cubic meters!
See the live demo on the gas and temperature board for an example of a gas boiler.
Successful measurements and economical consumption!
