Some businesses have introduced short-range wireless meters to enable centralized meter reading using unlicensed frequency bands – the small wireless method. However, there are a number of issues with this solution, including unstable data transmission, the inability to guarantee data security, high po...

I just noticed, your software-counter is higher than the gasmeter-counter. That is something I did not see with my setup and might be due to the reed-switch and perhaps bouncing. This might also hint why your setup required such a high debounce time. ...
(Gas/water/electricity) meter to read Raspberry Pi with memory card and connection to internet Raspberry Pi camera or some other camera. It must be possible to capture image using command line command. In case of dark room, some low consumption night light or similar might be necessary ...
The remote meter reading system has trouble recognizing dial pictures in extreme settings, challenging it to meet industrial production demands. This paper provides multiple attention and encoder–decoder-based gas meter recognition networks (MAEDR) for this problem. First, from the acquired dial ...
It, therefore, requires a water flow meter, two thermocouples in the water line and a fuel meter. In the indirect method, losses are measured. Returning to the energy balance, Eq. (5.31), we approximately have that (5.36)m˙w(h2−h1)=m˙FHHVF−m˙ghg−Q˙ and, therefore, the ...
