I use the 7kg propane gas bottles and want to buy a regulator that has a built in level gauge. Have looked but not sure what would be good and some where give the right readings. Anyone got one or any recommendations please.

From what I've read these gauges don't work very accurately.
Pressure from the bottle is a constant until the gas is nearly gone.

I use a luggage scale, the weight of the empty bottle is marked on the disc around the neck of the bottle.
Take a from b and you have your answer

Though I've no idea if it works, at £4 not exactly expensive

Slightly different approach but we always have two bottles so that when one runs out we've immediately got a spare until the empty one is replenished. Our motor home has storage space designed for two bottles so that's what we do.

We had one of those, it indicated a level when the gas ran out.....

I had a look at them and there was a lot of complaints about them, I am not sure how they work but my guess is that it is a temperature indicator,
and it will only work if you are using gas, what happens is the gas takes heat in from the surrounding area when it converts from a liquid to a gas, I think the liquid gas interface will be colder and will show up as a different colour, so have a look when you are using gas it might just work.

Ok the disc round the neck of a new bottle says 8.3kg I have weighed the new bottle at 13.88kg as you suggest.so that leaves 5.58kg . Am I right in thinking flo gas are under filling there 7kg bottles by 1.42kg scratchchin.

well flo gas do quote 8.3 kg as the tare weight on their website so in theory your bottle when full should weigh 15.3 kg
confused

Having looked around it may have something to do with air pressures and temperatures when filled? I am not a physicist so dont really understand why.

The one thing you do need to know is the empty weight, if you have scales you will know if you still have gas.
