No more struggling to shake the cylinder to guess how much gas you have left; with the Truma LevelCheck, you can quickly and conveniently check and monitor the quantity of gas remaining in your LPG cylinder from your smartphone.

The LevelControl uses ultrasound technology to detect the gas level and communicates via Bluetooth to the LevelControl App on your smartphone, providing information such as gas volume in kg, % fill level, days usage remaining, battery status, low gas level notification and more. Multiple LevelControl units can be monitored via the app and it can also be used with an iNet box and the Truma App for remote monitoring, where you will be sent a text message with the measurement results.

The LevelControl features strong magnets to attach it quickly and effortlessly to the base of steel cylinders, and it can be attached to aluminium cylinders using a separately available clamping sheet (please contact us for availability). A handy sign is included that reminds you to remove the LevelControl from the cylinder before exchanging it.

This system is perfect for use in campervans, motorhomes, caravans & boats, or even with BBQ gas cylinders at home.

Truma Level Control
26 April 2024  | 

I bought this product in 2022 and been monitoring my gas in two connected bottles for over the 2 years. Seen several reviews on different outlets with negative comments. I can only give positive feed back. Possibly the company could explain better about the method of measuring the levels and people could understand how it works. I have it on a 6kg GasLow bottle which is permanently linked to a 11kg bottle. Works perfect !

Doesn’t work

Put it on established a reading which went down to 3% (97% full) and stayed there until the bottle was empty- Bluetooth is very short range at best 1 to 2 metres . Very disappointing


Hi Robin, sorry to hear this. We have not had any other reports of these not working. We will contact you shortly about getting this unit checked out. Many thanks
