Speedrange Gas Level Indicator
Can be used on any size tank containing propane, butane or a mixture of these gases. It has a magnetic backing which allows it to be attached to the outside of the cylinder and reused again and again. The GLI has been designed to be placed at the base of the tank to give an indication when the gas level is running low and should not be used as a precise gauge.
