8.5 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 8-16: Selection of antenna (graph of distance in m against ε
r
)
Figure 8-17: Selection of antenna (graph of distance in ft against ε
r
)
1 Tank height / Measuring range [m]
2 Tank height / Measuring range [ft]
3 ε
r
for storage tanks with smooth product surface
4 ε
r
for process tanks without agitator or foam
5 All antennas:
- DN80/3¨ and DN100/4¨ Metallic Horn antenna: only for use in a stilling well*
- Wave Guide antenna: maximum measuring range is 6 m / 19.68 ft
6 DN150/6¨ or DN200/8¨ Metallic Horn antennas in a stilling well* or DN200/8¨ Metallic Horn antenna
7 DN200/8¨ Metallic Horn antenna in a stilling well*
* A stilling well is equivalent to the Wave Guide antenna option or a bypass chamber
