2.4 Mounting
An ECLIPSE Model 700 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 700 transmitter as this may cause excessive heat buildup.
Ensure that all mounting connections are properly in place
on the tank before installing the probe.
WARNING!
Overfill-capable probes such as the Model 7zP or 7zT
should be used for any Safety Shutdown/Overfill appli-
cations.
The Model 700 transmitter, when used with an overfill
coaxial 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 advan-
tage 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 150 mm (6")
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: Model 7zP high pressure probe (containing a glass ceramic
alloy process seal) should be handled with extra care. Handle
this probe only by the flange or NPT connection. If supplied,
remove transport hardware as shown at left prior to installation.
2.4.1 Installing a Coaxial Probe
(Models 7zP and 7zT)
Before installing, ensure that:
• Probe has adequate room for installation and has unob-
structed entry to the bottom of the vessel.
• Process temperature, pressure, dielectric, and viscosity are
within the probe specifications for the installation. See
Specifications, Section 3.6.
