3 Intended use
The unit continuously monitors the level of liquids without contact.
Bulk materials are detected depending on their properties (conical heaps, grain size, dielectric
constant, etc.).
The unit is suitable and approved for applications in closed tanks (according to ETSI EN 302
372) as well as in or above open tanks / plastic tanks (according to ETSI EN 302 729).
For applications in or above tanks / plastic tanks, the unit must be combined with the antenna
extension. Mount the antenna extension (
Without the antenna extension, the unit may only be used in an enclosed space (metal tank,
concrete tank, or similar enclosure structures made of comparable damping material).
In addition, the following is necessary for installation and operation:

Accessories)
Only use accessories from ifm electronic gmbh! The optimum function is not ensured when
using components from other manufacturers.
3.1 Application area
With its top-down installation, the non-contacting radar technology is ideally suited for level monitoring
and is virtually maintenance-free.
The unit combines the innovative 80 GHz technology with the FMCW method and smart algorithms to
maximise measurement accuracy and reliability in challenging fast-filling / fast-emptying applications.
3.1.1 Application examples
Storage tank:
Supports installation in a tank, ensuring smooth, uninterrupted
production processes.
Plastic tank:
Level monitoring in small and medium-sized plastic tanks by
measuring through the plastic roof.
