Truma LevelControl is a free app that offers a convenient and reliable way to check gas levels in your cylinder. It uses ultrasound to determine how much gas is left in the cylinder and displays the result in the app. The LevelControl attaches to the bottom of the cylinder and adheres magnetically to any steel cylinder, and with a clamping sheet, also to aluminum cylinders. The app is available for Android devices, and it works with all current European gas cylinders.

The Truma iNet System allows you to operate the LevelControl, your heaters, and air conditioners with the Truma app. The app also gives you the option of using Bluetooth to check the gas level, which functions conveniently and reliably in the vehicle and outside it when within range. The LevelControl app sends the measurement results by text to your smartphone, whether you’re at home or out skiing on the piste. The LevelControl is not suitable for plastic gas cylinders, refillable tank gas cylinders, gas tanks, or butane gas cylinders (camping gas).

In addition, the LevelControl won the European Innovation Award 2018 in the Overall Concept Equipment category, and it features a notification when gas levels are low and the ability to use several LevelControl devices at the same time.
