Application Example: Stillpipe
An alternate to the waveguide antenna, this option is also used for products with an ε
r
or
less than 3 or if extremely turbulent or vortex conditions exist.
Note: For ε
r
< 3, the lower 40cm of vessel level may not be measurable.
This mounting arrangement can also be used to provide optimum signal conditions on
foaming materials.
Suitable pipe diameters are 50mm (2) to 250mm (10).
Note: The measurement range is reduced to 13m (43) for a 50mm (2) stillpipe or
14.5m (47) for an 80mm (3) stillpipe.
