Designed to ISO 9001 standards and made in the UK, it offers a reusable, wipe-clean, and compact solution to avoid running out of gas unexpectedly during camping, caravanning, or motorhome trips. ## Description Product description Ever been caught short with an empty gas cylinder...Usually there is no way of telling how much gas is left. But with our handy gas level indicator, that will be a distant memory... Just place the gas level indicator (GLI) on the bottom half of the cylinder and switch on the gas.... The Liquid crystals change colour as gas runs low. Can be used on propane, butane or mixed fuel gas cylinders (avoid placing over a weld). Measuring 114 x 50mm it has a wipe clean surface. The GLI's magnetic backing means it can be attached to the outside of the cylinder. Product is reusable and made from flexible vinyl. This product comes with full instructions and holds the ISO 9001 World Standards and Procedures certificate. Legal Disclaimer This product is recommended as a warning device.

Review: Simple, cheap - and it works on our motorhome gas bottles - I'm not sure why other reviewers are struggling with this item. We have two, one for each of the gas bottles in our motorhome, and they seem to be working brilliantly. We tested when the bottles were both full, and they registered as such (remember to leave for at least 10 minutes when first putting onto the bottle before it will show an accurate result). We have now used part of one bottle, and it shows this. A great little item for the money. I doubt it will tell us to the minute when we will run out but, as our bottles are heavy and the back one is hard to remove, it saves us having to lift them and shake ot guess how much is left, and seems to give a very close approximation of usage. Review: Handy inexpensive if unclear indicator - After running out of gas halfway through cooking our sausages on one of our camping trips I was delighted to find this indicator and took it on our latest trip. The indicator is about 4" high and our gas bottle (907) is about a foot high with a ridge in the middle, the magnet is a little ridged and doesn't curl around your bottle so sits a little proud. You can estimate initially where your gas level is by either shaking the bottle, feeling the weight or you can place it up and down the canister when it is in use until you get a reading. The reading by the way is not obvious if you compare it to the leaflet. For some unknown reason on the COLOUR LEAFLET they have chosen to illustrate the readings in black and white! Also on the leaflet they show one column as an indicator and on the actual product there are multiple columns which wouldn't matter if they showed identical readings but they don't. Once in place and using the gas bottle, the left column seemed to have blue colouring and right column, which I took as the actual indicator, showed orange at the bottom, yellow in the middle and pale green to the top. Looking at the picture (if we are to assume yellow as the level) it appears that gas is low and there is about 2" left in the can. I assume that it works because we did see some change in colour when the gas was in use but do you read the orange, yellow or green colour? And I still don't know how long the gas will last me even if I do have 2" left because the colouring is vague and I don't know the rate at which it is burning. This coupled with the poor instructions made the product difficult to use. I can't really complain because it is a good price, it's compact and gives you a rough idea of what is left in the can so it is worth a punt. With better instructions it could be a good product. ## Features - Ever been caught short with an empty gas cylinder? - You won't get caught short of gas again!

Seems to do what it is supposed to do, just sticks to the bottom of the bottle and changes colour when the gas runs out. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/48689419-magnetic-gas-bottle-gas-level-indicator-for-the-caravan-motorhome](https://www.desertcart.vn/products/48689419-magnetic-gas-bottle-gas-level-indicator-for-the-caravan-motorhome) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
