Beam angle
The beam angle is defined as the angle
α
where the energy density of the radar waves reaches
half the value of the maximum energy density (3dB-width). Microwaves are also emitted outside
the signal beam and can be reflected off interfering installations.
Beam angle in dependence of antenna type (diameter).
Orientation
•
Recommended distance (1) wall –
outer
edge
of nozzle: ~1/6 of tank diameter
(FMR 230/231: min. 30 cm (12“),
FMR 240: min. 15 cm (6“)).
•
Not in the centre (3), interference can cause
signal loss.
•
Not above the fill stream (4).
•
It is recommended to use a weather
protection cover (2) in order to protect the
transmitter from direct sun or rain. Assembly
and disassembly is simply done by means of
a tension clamp (see »Accessories« on
page 39).
Tank installations
•
Avoid any installations (1), like limit switches,
temperature sensors, etc., inside the signal
beam (refer to beam angle).
•
Symmetrical installations (2), i.e. vacuum
rings, heating coils, baffles, etc., can also
interfere with the measurement.
Optimization options
•
Antenna size: the bigger the antenna, the
smaller the beam angle, the less interference
echoes.
•
Mapping: the measurement can be
optimized by means of electronic
suppression of interference echoes.
•
Antenna alignment: refer to "optimum
mounting position"
•
Stilling well: a stilling well respectively a
Wave Guide antenna can always be used to
avoid interference.
