Variable LPG Installation Kit

Design
The Variable LPG Installation Kit has been developed for FAFNIR sensors to measure the
level in LPG tanks without having to mount the sensor in the tank. Instead, an installation
tube is installed in the tank to hold the sensor for level measurement. The sensor can
therefore be inserted or removed from the the installation tube at any time without having
to open the tank.
The Variable LPG Installation Kit consists of an installation tube with LPG float (BUNA), a
compression/cutting ring fitting (non-detachable) with ¾" NPT external thread for process
connection, and a reducer with a PTFE compression fitting (detachable) for fixing the
measuring sensor (VISY-Stick LPG sensor), see figure below:
