Came across this wonderful little gadget . It shows the level of gas in a cylinder. Safe, reusable and accurate. Attaches to bottle using magnetic strip. We have one and its been so much better than memory or turning on the cooker ring and finding it has 'stopped'. Here is a place we got one from but there will be others on eBay. Take a look
2016 Update: Many of the modern light weight bottles now have a red / green indicator on the top, may be worth using as well assuming you can get to see it
2020 Update: Light weight bottles withdrawn, dangerous indeed we were woken at 2am by the carbon monoxide alarm when camping at the site at Brighton, very frightening, now safely replaced, you cannot get them any more
