8.3 Antenna selection
The graphs below show which antenna to select for the application based on:
• D, the measuring range,
• ε
r
, is the dielectric constant of the product being measured
Figure 8-2: Selection of antenna for liquid applications (graph of distance in m against ε
r
)
Figure 8-3: Selection of antenna for liquid applications (graph of distance in ft against ε
r
)
1 Distance, D [m]
2 Distance, D [ft]
3 Dielectric constant (ε
r
) range for storage/still well applications
4 Dielectric constant (ε
r
) range for process/agitator applications
5 DN80, DN100, DN150 or DN200 Horn antenna with a still well, or DN150 or DN200 Horn antenna without a still well
6 DN80, DN100, DN150 or DN200 Horn antenna with or without a still well, or DN80 or DN150 Drop antenna without a
