FAQ

1. "The sensor returns only a single echo and no further echoes. rd_2, ra_2, rd_3, ra_3 are 0."

This behavior is not a malfunction but is completely normal depending on the application or environmental conditions—and in many cases even desirable. In this case, the sensor has detected a clear, dominant target that reflects strongly enough to suppress all other possible echoes or classify them as irrelevant.

A single, stable echo means:

  • High measurement reliability with a clear surface or homogeneous fill level
  • Low interference reflections from tank walls, internal components, or surface structures
  • Optimal conditions for reliable level or distance measurement

Only if multiple relevant echoes are expected (e.g., in the case of complex tank geometries or overhanging structures) and are consistently missing, might it be advisable to check the sensor alignment, radar parameters, or environment.
For the "Smart Waste" setting (tmod = 0), only one echo is ever available, since the first detected object is recorded.

2. I would like to switch the sensor from the Smart Waste profile to the Liquid profile and back. How do I do that?

  • "Smart Waste" or bulk solids profile: tmod = 0
  • Liquid profile: tmod = 2

3. The sensor is detecting too many double reflections

Double reflections in radar (also known as multipath echoes or multipath reflections) occur when the radar signal does not return directly from the target but is reflected via detours, e.g., off walls, floors, tank structures, or internal components.

  • cfnr = 1
  • cfnr = 2 (in case of many double reflections)

4. The sensor shows no readings or "0" values

  • Increasecfsn
  • Increasesq

If the sensor consistently fails to provide readings or constantly displays 0, there may be various causes. This behavior is not necessarily a defect but is often due to configuration- or environment-related factors:

  • No target in the field of view
    → Check whether there is a reflective object within the configured range.
    → At very long distances or with poorly reflective surfaces (e.g., foam, open grating), the radar backscatter may be too weak.
  • Incorrect sensor alignment
    → The sensor may not be correctly aligned with the target surface (e.g., tilted or angled too much).
    → The main beam direction should be as perpendicular as possible to the target surface.
  • Inappropriate radar parameters
    → Check settings such as: radar filter type (e.g., for liquid or solid), sensitivity/gain, minimum and maximum range (r_min, r_max)
  • Interfering reflections or shadowing
    → Metal components, covers, grates, or proximity to walls can block the direct echo.
    → In this case, a valid measurement value may not be detected.
  • Data format or communication error
    → Make sure that the measurement data is being read and interpreted correctly.
    → A value of "0" can also mean: no valid measurement value received (depending on the protocol or data parser).
