57-606 ECLIPSE Model 706 Guided Wave Radar Transmitter
2.4 Mounting
An ECLIPSE Model 706 GWR probe can be mounted on
to a tank using a variety of process connections. Generally,
either a threaded or flanged connection is used. For infor-
mation about the sizes and types of connections available,
see Probe Model Numbers, Section 3.7.2.
NOTE: Do not place insulating material around any part of the
ECLIPSE Model 706 transmitter as this may cause excessive
heat buildup. The figure to the left shows an example of prop-
erly installed insulation. Insulation is critical in high temperature
applications where condensation can occur at the top of the
probe.
Ensure that all mounting connections are properly in place
on the tank before installing the probe.
Compare the nameplate on the probe and transmitter with
the product information to confirm that the ECLIPSE
probe is correct for the intended installation.
WARNING!
Overfill-capable probes such as the Model 7yD, 7yG,
7yJ, 7yL, 7yP, or 7yT should be used for all Safety
Shutdown/Overfill applications.
The Model 706 transmitter, when used with an overfill
coaxial or caged probe, is capable of measuring true
liquid level to within specification all the way up to the
face of the flange or NPT connection. This is a very
unique advantage as compared to other Guided Wave
Radar (GWR) devices that may infer level at the top of the
probe when signals are lost or uncertain. Refer to Section
3.2.6 for additional information on overfill capability.
All other ECLIPSE probes should be installed so the
maximum overfill level is a minimum of 6" (150 mm)
below the flange or NPT connection. This may include
utilizing a nozzle or spool piece to raise the probe.
Consult factory to ensure proper installation and operation.
WARNING!
Do not disassemble probe when in service and under
pressure.
NOTE: Models 7yD, 7yJ, 7yL, 7yM, 7yN, 7yP and 7yS High
Temperature/High Pressure probes (containing a glass ceramic
alloy process seal) should be handled with extra care. Only
handle these probes by the flanges or NPT connections.
2.4.1 Installing a Coaxial Probe
(Models 7yD, 7yP, 7yS, and 7yT)
Before installing, ensure that:
• The model and serial numbers shown on the nameplates of
the ECLIPSE probe and transmitter are identical. For opti-
mal performance (and correlation to the Calibration
Certificate included with all units), transmitters and probes
should be installed as a matched set.
