what does at mean when the needle is in the yellow bit?

Many thanks

I presume that because red is on the other side (danger low gas and green is between the yellow and red) that you have a full cylinder of gas, which you will be able to confirm. If you have used it for a while, then maybe the needle is stuck or red means that the pressure it too high in the gas bottle from heat etc = danger and yellow means you have no gas left.

[dannymack]

Yes Ben Spruce seems right, I'm guessing its a pressure of how much gas you have in the bottle and when you get low the needle will work its self to red
You will have to let us know as I could do with one, never know when I'm gonna run out until it does

[andyM]

I would agree with Spruce.
Yellow is empty.

The trouble with those gauges Danny is that they rely on pressure to tell you how much gas is left and are very inaccurate.

The liquid gas turns to vapour in the top of the cylinder and stops when the pressure gets to a certain level. That pressure keeps the remaining gas in liquid form. When you draw some vapoured gas off for your boiler the pressure drops inside the cylinder allowing a little more liquid gas to turn to vapour.

The process works very well until the end when there is hardly any liquid gas left and by then you are just about to run out of gas. This is an issue the LPG tanks used in motor homes still experience (see RV forum complaints), so over time owners get pretty good at estimating how much gas they have left. My dad was pretty good at doing that over 50 years ago with his gas bottle in our caravan when were were kids.

This is why the safefill gas bottle is a good idea imo as you can see how much gas you have left in the bottle. (Unfortunately, Morrisons LPG garage in Redcar 5 miles from where we live won't allow them to be filled there now either.) If you have a fitted LPG tank then topping up when you are passing a garage is easy.

TBH I put each foot on either side of the fence leaving Ben to tell us. I know he bought his setup at the same time as Daz and Daz is using his. I haven't seen any posts with Ben using his yet I don't think. (There must have been an instruction slip in the box when he bought the regulator - has he bought a regulator yet I wonder?)

If he has connected his unit up and used it, then he would be able to tell us where the needle is with a full bottle of gas. After that the rest is easy to figure out.

Which is most dangerous; running out of gas or the gas bottle getting too hot and in danger of exploding? So is this a friendly information gauge for the user or a warning gauge? I did an internet search but found nothing.

The sales illustration is with the needle on yellow and is a photo of the unit itself not connected to a gas bottle, so if I had to choose Andy, I would go with you and say yellow was empty.

Hi Spruce,

Thanks for your message. Yes i bought the regulator and used it, no instruction in the box regarding the manometer!
the needle is just after the yellow section(green section) with a full bottle of gas and even after 5 days of use   the needle didn't move!

[dannymack]

Ooo ill leave from getting one cheers Bruce. I did have the clear gas bottle but they don't hold much gas. I did have one of those things you put in the side of the bottles that have magnets what a load of rubbish that was !!!

Hi Ben
This is the problem. That needle won't move until the very end of your gas and then it will drop very quickly. Please let us know how you get on with it once the bottle is nearly used.

Well done for getting your system up and running. How are you finding it?

I had a gauge like that once,
