4.12.1 Standard

The standard profile sets the parameters in a way that many common applications ( e.g. a clear defined

target without other without disturbing effects) can be solved. The sensor should deliver reasonable results

when operating with good targets (material / surface structure / size / angel / etc.). This profile is the default

setting.

The Profile "Fill level fluid slow" can be used for a detection of fill level in e.g. liquid tanks. If the level in the

tank is not changing slowly and the fluids have high viscosity (e.g. glues / pasty goods / etc.) the this profile

should be selected. The profile works well inside a tank where no barriers or disturbing elements are present

(mixer, stirrer, bars, pipes). If a stirrer is present please use the fast profile 4.12.3. Take care when operating

inside a tank where reflections (e.g. side reflections) can influence the measurement. Foam in general might

have a negative effect on the measurement of the liquid level. The profile can also be used for solid materials

that have a high percentage of humidity.

Use this profile if the changes of the level are fast. if e.g. the filling or emptying of tanks requires a stable

measurement. Also when disturbing object like mixer are interfering with the radar beam we recommend fast

profile. Rotations of the stirrer between 20 and 60 rot/min are covered by the original settings. For faster or

slower movement parameters like disruption filter should be adjusted. Use this profile also for level with

waves or out sticking objects.

Compared to the fluid substance the handling and detection of solid substance is more difficult. As the

structure of the substances is mostly not flat (compared to the surfaces inside liquid tanks) this has a strong

influence of the measurement accuracy. The predefined profile is parametrized in a way to obtain adequate

results when detecting e.g. a level of granular substances inside a silo. Due to the physically detection

capability of radar radiation a grain size of <1 mm and >5 mm can be detected easier the objects with size

within 1 and 5 mm. As mentioned a lot of different parameter of the tank / reservoir / vessel environment and

the physical characteristic of the substance might have an impact on the signal so the sensor parameters

must be adjusted accordingly. Use this profile also when the material forms a pile.

If using the "Fast detection-Profile" the sensor will try to find as fast as possible any target. The Sensor will

be adjusted to find also the fastest and smallest target. The profile can be use e.g. for environmental scan or

collision avoiding application, generally if the sensor has no object in its field of view most of the time. As the

sensor is set very sensitive the risk in finding wrong and not desired targets is given, therefore use only if

necessary. The profile uses no filtering.

The tracking profiles are needed if the goal is to follow a detected target over a longer distance. Once the

target is detected (set) the sensor will try to stick with this object as far as this one is detected. The sensor

will search a new target by a defined peak selection only if the "old" one is completely lost.

Tracking is needed if disturbing objects in the view of the sensor have higher or stronger reflections than the

wanted target and this one is in move. Due to the nature of the profile a categorization to a specific speed

level of the targets is needed. See also 4.7.5
