Eclipse 705 Installation And Operating Manual page 3

MOUNTING
IMPORTANT:
To avoid damaging during transportation, Eclipse
the inner antenna. The 3 screws have to be removed prior to installation. They are located nearby the process connection. A
separate label is attached to draw the attention to remove the screws.
To avoid moisture ingress in the housing, covers should be fully tightened at all times. For the same reason, cable gland and
plugs should be properly installed in the cable entries.
The unit is preconfigured from factory, based on given application details (when available). Therefore transmitter and GWR
probe have the same serial n°.
Please make sure that corresponding serial numbers are mounted together.
Coaxial type GWR probes
(7MD - 7MQ - 7MR - 7MS - 7MT)
min 25 mm (1")
from tank bottom
Customer supplied brackets are recommended
per each 3 m length. (Required for WGH § 19
installations.)
Overfill safe and Overfill proof
Eclipse 7MD/7ML, 7MR/7MM and 7MT/7MN coaxial GWR
probes are "Overfill safe" in use and "Overfill proof" certified.
Overfill safe means that the unit is capable to measure up
to the process connection.
Overfill proof protection (such as WHG or VLAREM) cer-
tifies reliable operation when the transmitter is used as
overfill alarm but assumes that the installation is designed
in such way that the vessel/ cage cannot overfill.
Eclipse 7MQ/7MS has a transitioning zone (zone in which
the unit does not measure accurately) at the top. Maximum
level should not be higher than 25 mm (1") up to 200 mm
(8") (depending dielectrics - see probe specifications) below
the process connection. This may include utilizing a nozzle
or spool piece.
Note: When using the 7MQ or 7MS probe, keep transmitter
and probe matched as a set.
7MD/7ML large coax probes are shipped with 3 transport screws, securing

Coaxial type GWR probes: Flushing connection
(7ML - 7MM - 7MN)
Size: 38 mm
(1 1/2") or
adjustable
wrench
Not important
Note: The flushing connection allows to purge the inside of
the coaxial probe without dismantling. Re-assure the use of
compatible purging liquid/gas to avoid unwanted chemical
reaction.
Metallic (or any conductive) obstructions in the tanks
Metallic obstructions have no influence on the measuring
performance of coaxial GWR probes.
Turbulence
Customer supplied mounting brackets are recommended
per each 3 m (10') length and have no influence on the mea-
suring performance of coaxial GWR probes.
Stillwell /cages
Coaxial GWR probes are ideally suited for use in stillwells
or cages. There is no min. clearance allowance to be taken
into consideration.
Shortening of probe length
Coaxial GWR probes can be easily shortened on site when
a procedure for this is strictly followed. This procedure can
be separately obtained from factory.
