Every case below comes from a real installation: the site photo, the echo spectrum captured in the field, and the one change that put the reading back on track. Our application engineers write them up so you can recognise the same symptoms before they cost you a site visit or a replacement unit.
Both cases trace back to the same root-cause family – an unwanted echo close to the transducer. The fix is simple once you know what you are looking at, and the lessons apply to radar and ultrasonic level measurement alike.
Seeing a similar symptom on your own site? Send us the echo spectrum and a photo of the installation – our engineers will tell you what the false echo is and how to remove it.
