Environmental considerations
The Rosemount 3107 and 3108 ultrasonic transmitters are Intrinsically Safe (IS) approved for
hazardous area installations.
1.
The 3107 is designed for open or closed tank installation. It is weatherproof and
protected against the ingress of dust
2.
The 3108 is designed for open channel flow measurement. It is weatherproof and
protected against the ingress of dust
3.
Avoid installing the 3107 and 3108 near heat sources

Mechanical installation
Guidelines
1.
Mount the transmitter above the liquid using the 1-in. thread provided, but not closer
than 12 in. (0,3 m) to the surface. The transmitter does not detect any liquid surface
closer than 12 in. (0,3 m) to the transmitter face. (See
“Mounting the transmitter above
the liquid surface” on page 11
).
Optional flanges and bracket kits are available to help mounting.
(See
“Spare parts and accessories” on page 120
.)
2.
The transmitter should be mounted vertically to ensure a
good echo
from the liquid
surface. The transmitter beam half angle is 6 degrees (See
).
3.
Obstructions in the tank, or well, may generate echoes which can be confused with the
real liquid surface echo. Obstructions within the beam angle generate strong false
echoes. Wherever possible, the transmitter should be positioned to avoid false echoes.
