OVERVIEW
What it does and why it is built this way
The LV-220 sends low-power radar pulses down a probe. The reflection at the liquid surface sets the level, and a second echo reveals an oil-water interface.
Because the signal follows the probe, it is unaffected by tank shape, angled walls or foam, which makes it a robust choice for separators and process vessels.
