Radar level sensing function
In plain English
What does Radar level sensing function mean?
A radar sensing function uses radio-frequency signals to obtain information about a target or surface.
A simple example
A suitable level installation can interpret reflections from the measured surface.
What the drawings help you do
Show the sensor’s radio-frequency path towards the measured surface and identify the reported level reference. A distance to the surface and a level within a vessel are related through the selected geometry. They should not be treated as identical values without defining the reference points.
- Level reference
- The defined point from which the reported level is measured.
- Reflection
- The returned radio-frequency signal used by the sensing method.
Before using this reference
- Identify the measured surface and level reference.
- Reference the selected sensor and installation geometry.
- Show the electrical output and receiving control system.
Is measured distance automatically the liquid level?
The relationship depends on the sensor position and vessel reference. The selected configuration converts the sensing result into the intended level quantity; the functional graphic does not supply that geometry.

A distinction that matters
The sensing principle does not establish suitability for every vessel, material or installation.
