Ever been caught short with an empty gas cylinder? After all there's no way of telling how much is left and it can so easily run out halfway through a barbecue or worse on a cold winters day when using a gas heater.
Just place the magnetic indicator on the lower half of the cylinder and once the gas is turned on the colour of the bars will change below the liquid level telling you how much gas is left. Don't get caught short again.
