Gas Level Stick

GASLEVEL Stick by Gaslock is a gas level indicator which looks something like a thick pen.

 Just 4.5 inches high and 0.6 inches wide, the device is very practical and uses modern ultrasound sensors. It measures the fill level of propane gas cylinders within a few seconds. GASLEVEL Stick is simply held vertically with its end against the gas cylinder and moved downwards until the indicator lamp changes from red to green, showing the area which still contains gas.
