In fact they also measure the rate at which energy is being used. This is important for safety checking and testing of appliances. For gas appliances they are an utter PITA as on an old analogue meter we used a stopwatch to time the needle on the dial for one whole revolution but on smart meters (of which there are about 15 types in use IIRC), we have to look up in pages of instructions how to do it on each different make/model of smart meter. And as you can probably guess, every meter has a different method of measuring gas rate..
You had "instructions"?
A friend had one at her new flat. I went online to find the 'instruction manual' (as you do). There wasn't one...
I constructed one, on an A4 sheet, by scraping and editing stuff I found on the Web. Smart huh?
Needless to say, she was completely lost when it came to the IHU (user display). I played with it for about 10 minutes and, being technically minded, was able to eventually decode its functioning enough to park it on the only option she wanted.
I bet this is all "World beating".
