I used to service the air compressors at British Gas training centre outside Bolton in the 70's. There was a room with hundreds of meters where they were being calibrated.

Very intriguing mechanism, such basic mechanics. For the sake of argument would the rotation reverse if you were to push air through the outlet as opposed to suck with your vacuum. Great video

So many moving parts in those older ones! Plastic components and I wonder how long they hold their calibration for! I can't believe it's not an industry standard to have these meters calibration checked on a regular basis. The ultra sonic meters will be far more accurate and repeatable but again, will still require calibration regularly to maintain optimum accuracy I guess. Interesting video, especially for us flow geeks. 👍🏻

The new ones are very susceptible to magnets being put on them, the magnets don't do anything but the rumour has spread. i have come across quite a few new meters with magnets stuck to them.
@markrainford1219 Жыл бұрын
They will be accurate for a long time because they work on a fixed volume rotating a crank. The density of gas will change with temperature and hence calorific value though. But this is accounted for.

Hi, Thank you for making this video and I found it really helpful. I live in an apartment and noticed that my gas usage had a 400% increase compared with same period last year. At first I thought I might got a faulty meter (i.e. my meter went wrong at some time point last month). However, after watching this video, I realized that it is really difficult for a gas meter to go wrong, and the reason for my abnormal increase of gas usage might be somewhere else. May I ask do you have any ideas about possible explanations for this?
@tomkatgastraining8 ай бұрын
If I was you I would make a note of the gas meter reading and don’t use any gas for an hour and see if the readings increase. You could also have a gas leak that is in a place that you can’t smell it. If you have concerns get in touch with your gas supplier or get a gas engineer out to do checks.

Hi, I followed your suggestion and turned off everything when I leave my apartment this morning. And when I return home, I found my gas meter shows that I consumed 1 therm during the daytime. It seems that there exists a gas leak somewhere. I will contact my gas supplier tomorrow. Thanks again for your suggestion @@tomkatgastraining

There is a rotating magnet in a number of modern meters which can be used to track usage, wondering why they didn’t use these instead of the £££ smart meters? What’s your thoughts on having something inside the meter cabinet counting the rotation of that magnet so they can monitor gas flow? What are your thoughts on Low voltage battery or low voltage (5volt) direct wired? There is an actual device for this that’s purchasable which has a Hall effect sensor but you’d need to push cable though into the house so the seal would be broken so how should that be sealed? Any advice?

Very interesting and food for thought. I've had the worst week at work in many years, everything i've been to has been trouble. Went to a gas leak and had the ecv snap off in my hand when testing................... Brown trousers moment, until I hammered a wooden bung into the open end from the street. Then a mechanical meter with the outlet nut rusted on to meter tail and leaking. Called the board out and the fitter heated the tail to get it off: I would have been worried about blowing the meter bellows up? and looking at this video: The plastic spacer to seal the outlet from the bellows could be damaged by heat! Would this then bypass the metering system? at the least it must have put the metering out of calibration, as no way can that plastic stub NOT have been damaged........ Interested to know your thoughts. Cheers.
