With the Truma LevelControl you can determine the level of your gas cylinders precisely and check it conveniently using the Truma App. The well thought out design is based on the shapes of the different cylinder types and is the first device of its kind that can be used on all cylinders. Integrated powerful magnets on the contact ring and an ergonomically designed handle make fixing the Truma LevelControl to the base of steel cylinders child’s play. The sturdy housing and the rubberised surface transitions ensure a long service life. A battery-operated ultrasound sensor determines the gas level in the cylinder through travel time measurement. The current level is sent to your smartphone or tablet via battery-saving Bluetooth Low Energy. The clear user interface of the app enables you to see all the information quickly, such as the expected remaining time and the state of charge of the sensor battery. With the Truma LevelControl, unexpected empty gas cylinders are now a thing of the past.
