BEFORE YOU INSTALL
It is important to position the transmitter for reliable ultrasonic level
measurement. The transmitter may be site-tuned to deal with most application
conditions, but it is recommended that the following guidelines be adopted
wherever relevant.
NOTE:
The Rosemount 3100 Series is designed to be mounted in a non-metallic
fitting or flange . The use of metallic fittings/flanges is not recommended.
Please see “Accessories for The Rosemount 3101/3102/3105“ on page A-9.
General Considerations
Guidelines:
a) Installation must be carried out by suitably trained personnel in
accordance with the applicable code of practice.
b) If the equipment is likely to come into contact with aggressive substances ,
it is the responsibility of the user to take suitable precautions that prevent
it from being adversely affected, thus ensuring that the type of protection
is not compromised.
Aggressive Substances are acidic liquids or gases that may attack metals
or solvents that may affect polymeric materials.
Suitable Precautions are regular checks as part of routine inspections, or
establishing, from the material's datasheet, that it is resistant to specific
chemicals.
c) The equipment should only be cleaned with a damp cloth; do not use
solvents.
d) The equipment is not intended to be repaired by the user and is to be
replaced by an equivalent certified unit. Repairs should only be carried out
by the manufacturer or approved repairer.
e) The transmitter is Double Insulated , and therefore Protective Earthing is
not required. Internal and external earth terminals are provided on
equipment with metal housings for Functional Earthing only.
f) To maintain protection against the possible spread of fire, the supply to
the equipment must be limited to 3.75 Amps by a fuse or other means.
g) Note that if the equipment is used in a manner not specified by the
manufacturer, the protection afforded by the equipment may be impaired.
h) This transmitter is classified Type A in accordance with the European
EMC directive 2004/108/EC. To ensure electro-magnetic compatibility, in
any member state, it should not be installed in a residential area.
NOTE:
It is not advisable to mount the transmitter in close proximity to a source of
electrical noise such as a variable-speed drive, or other high-powered
electrical device.
