The device is not suitable for plastic gas cylinders, tank gas
cylinders that can be filled, gas tanks or butane gas cylinders
(camping gas).
To ensure reliable measurements, the measuring head
needs to be cleaned with a damp cloth (without a deter-
gent) every time before use.
A soiled measuring head can lead to inaccurate measure-
ments. Aluminium cylinders, in particular, transfer dust parti-
cles that can impact on the measuring process.
Soiled or rusty gas cylinders are usually difficult to measure.
The measuring process can also be impeded by the following:
– an invisible area of rust inside the gas cylinder
– a very thick coat of paint on the outside of the gas cylinder
– stickers on the outside of the gas cylinder
– (icy) condensation on the outside of the gas cylinder
– indentations or severely scratched gas cylinders
Cleaning the gas cylinder or taking the measurement at a dif-
ferent point is usually successful.
Determine the filling level
Determine the filling level by taking several individual meas-
urements at various heights on the gas cylinder (from the bot-
tom to the top).
Do not drag the device along the gas cylinder.

Intended use
Truma LevelCheck is a mobile filling level indicator for all (pro-
pane / butane – LPG) steel or aluminium gas cylinders with a di-
ameter of 200 to 350mm. The device recognises whether there
is liquid in the cylinder at the measuring point and indicates this.
Important notes
A gas cylinder is filled with max. 80% of its volume. The re-
sulting filling level of a full cylinder changes depending on the
gas mixture (ration of propane / butane) and the temperature.
