Intended use
The LevelCheck is a mobile fill level indi-
cator for all (propane/butane – LPG) steel
or aluminum gas cylinders with a diame-
ter of 7.9 to 13.8 in (200 to 350 mm). The
LevelCheck recognizes whether there is
liquid in the cylinder at the determining
point, and indicates this.
This LevelCheck is designed for private
use only.

A gas cylinder is filled to a max. of
80% of its volume. The fill level of
a full or partly filled cylinder changes de-
pending on the gas mixture (ratio of pro-
pane/butane), the temperature, and indi-
vidual cylinder volume. The LevelCheck
is not an exact measuring device, but is
instead an indicating device to determine
the approximate fill level of a gas cylin-
der. In order to exactly measure (in lb or
kg) the LPG contents of the cylinder, a
scale must be used.
The LevelCheck is not suitable for plastic
gas cylinders and automotive propane
tanks.
To ensure reliable indications,
the ultrasound head (Fig. 1-1)
must be cleaned with a damp cloth
(without detergent) every time
before use.
A soiled ultrasound head (Fig. 1-1) may
lead to inaccurate indications. Aluminum
cylinders, in particular, transfer dust par-
ticles that can impact on the determining
process.
