Mechanical Installation
3.2.1
Location and positioning guidelines
Choosing the proper location to the unit should consider every aspect of the vessel and contained
materials, including the silo or vessel dimensions, type of material and angle of repose, locations of filling
and emptying points, maximum level of material, internal construction and moving parts and any other
consideration which may possibly affect the performance.
Note
It is strongly recommended to install the unit according to the
Locator
PC software results provided by
the factory for installation location and positioning. Contact Emerson Customer Support for assistance.
Moisture and water condensation
Use the recommended cable gland and tighten the cable connection. For additional protection against
moisture, lead the connection cable downward in front of the cable entry. Rain and condensation water
can thus drain off. This applies mainly to mounting in areas where moisture is expected (e.g. by cleaning
processes), or on cooled or heated vessels.
Pressure
The process fitting must be sealed in the case of a low/high pressured vessel. Before usage, verify that
the sealing material is resistant to the stored medium. The maximum allowed pressure is indicated on
the type label of the sensor.
Installation location
Choosing the proper installation location for the unit is an important part of the installation process. The
wrong mounting location may result in erroneous measurements or loss of performance.
The following factors must be taken into consideration while choosing the installation position:
Vessel dimensions
Filling and emptying point locations
Internal structure or support
Other restrictions related to the proximity of noisy devices (such as electrical motor) and any other
element which may affect the proper operation of the Rosemount 5708.
Note
When mounting the Rosemount 5708, do not install it near the vessel wall. Installing it near the side wall
will result in bad performance and will not be supported. The Rosemount 5708 cannot be
mounted at a distance less than 24-in. (600 mm) from the wall or filling points.
Installing at the center of the vessel is not recommended, since the perfect symmetry from all sides
toward the Rosemount 5708 may affect the resolution of the echo.
3.2.2
Rosemount 5708 orientation
Mounting direction
Mounting at a specific direction is important. The ridge on the antenna and the notch on the top of the
thread (representing antenna no.1) should be directed toward the center of the vessel.
