Quick Start Guide
Components of the transmitter
The transmitter has a housing containing advanced electronics to generate ultrasonic
pulses, process the resultant signals, and provide a 4–20mA and HART output.
There is a factory-fitted cable for the signal output and connecting an external power
supply. The 3108 has a factory-fitted Remote Temperature Sensor.

Considerations before you install
Install the transmitter where it is protected from ultraviolet radiation to prevent long
term degradation of the plastics used in its construction e.g. shrouded from direct
sunlight.
Note
See also “Product Certifications” on page 21 for special conditions for safe use.
General
Installation must be carried out by suitably trained personnel in accordance with
the applicable code of practice.
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.
The equipment should only be cleaned with a damp cloth; do not use solvents.
