What it is not the answer for
Read this before asking for a price: one of these conditions is what turns a good meter into a bad installation.
- Tanks where the dielectric constant of the medium is very low and the surface is flat and calm
- Very narrow standpipes or nozzles shorter than the antenna's near-field requirement
- Foam layers that absorb the 80 GHz signal completely, such as thick chemical froth
Maintenance and service life
Keep the lens clean: a wiped lens once a year is usually enough, and a coated lens is the first thing to check when the echo is lost. Verify the empty-tank reference after any tank modification. No moving parts.
Applications
Where this model is used
Each application names a measuring point and the conditions that decide the selection.
