The LLF40 series is designed as a compact internal
fitting device, with a wide range of options, making
this ideal for size sensitive applications. Mounting
of this series requires access to the inside of the
tank.
* ETFE cable needs to be selected in order to achieve the maximum temperature rating

These devices are particularly suitable for detecting
low levels of liquids in the bottom of tanks and
containers, and for lower SG liquids. Typical
applications include vending machines, commercial
washing machines and evaporator units.
