2.6 Container Considerations

2.6.1 Shapes

The SLG 700 transmitter may be used in any shape of container. In general, it is designed
to be mounted vertically on top of the container, although angled mounting is also
possible. See section

2.6.2 Materials (plastic vs. metal)

The transmitter may be successfully used in containers made of any materials. When
planning the installation of the transmitter be aware that metal walls of the container
reflect the measuring signal and in some circumstances may help amplify the useful
signal. Polymer walls of the container are transparent to the measuring signal. If the
transmitter is installed close to a polymer wall, the measuring signal may reflect from
metallic elements that are outside of the container. In addition, a transmitter installed very
close to a polymer wall may experience greater signal attenuation which can reduce the
measurement range of the instrument.
To mount a transmitter with threaded or small flange connection in a non-metallic
container an additional signal reflector is required. Refer to section
When the transmitter is installed in a non-metallic container a coax probe is recommended
if immunity to radiated electromagnetic fields (as per EN 61326 & IEC 61000-4-3) is
required.
