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.
This is why i love derek and his videos straight to the point making it easy for us to understand i always wanted to know what was inside those things and what is 4 chambers thanks derek your a star keep them vids coming.
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
The Parkinson Cowan meter you opened was notorious for having a faulty index that jumped forward randomly, especially if the serial number started with a "D"
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.
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.
After heavy rain fall fron 14 april in peshawr, our gas meter reading has stopped but gas is still coming in our i think some water has entered, is it possible after some sunny days water evaporates and meter could start working again
Hi Derek, thanks for the video. I have the same as the one you are showing (Schlumberger), and my meter reading (the actual clock) stopped working. Do you know how to fix this, please? Any advice is much appreciated
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?
Did you see how slow the meter turned? What you save in gas you would pay in super expensive electricity. So, you would need to bypass your electric meter first.....
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.
@@julianhawker7672 ...So then I would have thought that every I dont know say 20 years it must be a Service requirement to change the ecv with a new one. Although the pressure is not that hard, but the toxic smell and the @ it gushes out is a maximal situation involving exposure to danger . I think I am going to invest in a nuclear PPE for such a situation. You surprise me by still being in the trade. lol
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?
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
@@dreddwailing5505 What u said is indeed true!!!! I spent 1 month studying the pipes in the apartment building, and finally found out that I have been paying bill for the guy living downstairs for more than 1 year. What's more frustrating, it took me 4 months to fight with the gas company (National Grid) to get my money back.
Sir if we put engine used oil 20 w 50 in side can it's work slow ??? What will happen if we put Oil in metter intake what will happen it will work slow or fast or Stop working plz guide and make video on it Thanks
Derek! Off subject but could you help me with a question mate, new gaffa at work says that I'll have to be put through my tpcp1a even though I've got my tpcp1? Is he correct, I thought the tpcp1 superceded and encompassed the tpcp1a
