Mounting: Stillpipe or Sidepipe
An alternate to the waveguide antenna, this option is also used for products with an ε
r
less than 3 or for extremely turbulent or vortex conditions. This mounting arrangement
can also be used to provide optimum signal conditions on foaming materials.
Suitable pipe diameters are 2 (50mm) to 10 (250mm). A rod antenna or a horn antenna
may be used.
Note:
: :
: The measurement range is reduced to 13m (43) for a 50mm (2) stillpipe or
14.5m (47) for an 80mm (3) stillpipe.
Smoothness
One continuous length of metallic pipe is preferred (no joints). If long length dictates the
need for joints, then you must machine the joints to close tolerances (± 0.25mm [±
0.010]) and weld a connecting sleeve on the outside.
See P655 on page 67.
Ensure there is a vent at the upper end of the surge pipe to equalize pressure and keep
the liquid level in the pipe constant with level in the vessel.
vent hole
Suitable pipe diameters are 2 (50mm) to
10 (250mm).
You can use either a Rod or Horn
antenna.
