| Applies when | vapor, foam, dust, off-gassing, chemical vapor |
|---|---|
| Avoid | ultrasonic level (Instrumentation) |
| Recommend instead | (Instrumentation) |
| Rationale | Ultrasonic (sound-based) level sensing attenuates and fails in dense vapor/foam/dust; radar (electromagnetic) does not share that failure mode. |
| Confidence | confirmed |

This is a general engineering rule derived from real field/case-study evidence, not a substitute for a project-specific specification review — confirm against your exact process conditions before ordering equipment.
