Sensor head and electronics are separate: only the compact \u003cstrong\u003esensor head (IP67)\u003c\/strong\u003e goes into the container. Its lens antenna focuses the radar signal into a \u003cstrong\u003emeasuring cone of ±3°\u003c\/strong\u003e, so it measures past walls, pipes, pumps and floats, even in \u003cstrong\u003enarrow or crowded shafts\u003c\/strong\u003e.
