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.
