THEORY OF OPERATION The Rosemount 3100 Series transmitter is designed to be mounted above a
liquid, and uses ultrasonic pulses to continuously measure the distance to the
surface of the liquid. The microprocessor-controlled electronics calculates
distance to the liquid level from the time delay between the transmitting and
receiving of the signals (Figure 2-1).
When programmed with the bottom reference of the application – usually the
bottom of a tank – The Rosemount 3101 will compute the liquid depth (level),
and output a 4–20 mA signal proportional to that level.
The Rosemount 3102 and Rosemount 3105 can compute level,
distance-to-surface, volume, or flow, and output a 4–20 mA signal
proportional to the selected variable.
An LCD inside the enclosure displays the selected measurement.
Programming is achieved using integral push buttons inside the enclosure, or
by remote communication using HART®(on The 3102 and The 3105 only).
The 3105 may be mounted in a hazardous area if powered from a protected
power supply.

SYSTEM
ARCHITECTURE The Rosemount 3100 Series is loop-powered which means it uses the same
two wires for both power supply and output signal.
The transmitter can be connected to any suitable 24 Vdc power source using
two-core, shielded cable.
On The Rosemount 3101, the output is a 4–20 mA analog signal.
On The Rosemount 3102 and Rosemount 3105, the output can be a 4–20 mA
analog signal or a digital HART signal.
NOTE
It is possible to use the multidrop function with the HART protocol. In this
case, communication is restricted to digital since current is fixed to 4 mA.
The transmitter can easily be configured by using a Rosemount 3490 Series
Control Unit. Alternatively, a Field Communicator, or a PC with AMS™Suite:
Intelligence Device Manager software can be used to configure the
transmitter.
The transmitter can be connected to a Rosemount 751 Field Signal Indicator.
A comprehensive specification for the Rosemount 3100 Series is in the
section “Specifications” on page A-1.

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.

MECHANICAL
INSTALLATION
Mounting
Considerations Guidelines:
a) The transmitter should be mounted above the liquid surface using the
2-inch thread provided.
(See “Mounting the Transmitter Above the Liquid Surface“ on page 3-5.)
(See “Accessories for The Rosemount 3101/3102/3105“ on page A-9.)
b) The transmitter should be mounted as near vertical as possible to ensure
a good echo from the liquid surface and maximum echo size received.
The beam angle (to the half-power-point) of the transmitter is 12 degrees
inclusive.
c) 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.
d) To avoid detecting unwanted objects in the tank or well, it is advisable to
maintain a distance of at least 1.3 in. from the center line of the transmitter
for every foot (11 cm per meter) range to the obstruction.
(See Figure 3-1 on page 3-4.)
e) If the transmitter is located near the side of the tank or well, there will be
no false echo generated if the wall is smooth and free of protrusions, but
there will still be a reduction in the echo size. To avoid large echo size
loss, it is recommended that the transmitter not be mounted closer than
12 in. (0,3 m) to the wall.
f) Fatty, dirty, or viscous liquids can cause a “scum line” to build-up on the
tank or well wall. Avoid false echoes by enabling the “scum line
prevention” software feature in a Rosemount 3490 Series Control Unit.
g) If the transmitter is mounted in an enclosed tank, avoid mounting the
transmitter in the center of the tank roof because this could act as a
parabolic reflector and create unwanted echoes. Avoid applications where
heavy condensation could form on the transmitter face.
h) If the transmitter is mounted in a stand-off or nozzle, the transmitter face
should protrude be at least 0.2 in. (5 mm) into the tank. If this is not
possible, see “Mounting the Transmitter Above the Liquid Surface“ on
page 3-5.
i) If the transmitter is used in environments where direct sunlight can cause
very high surface temperatures on exposed instruments, a sun-shade is
recommended.
j) The transmitter will not detect any liquid surface closer than 12 in. (0,3 m)
to the transmitter face.

Liquid Surface
Conditions Guidelines:
a) Foaming liquids can reduce the size of the returned echo because foam is
a poor ultrasonic reflector. Mount an ultrasonic transmitter over an area of
clear liquid, such as near the inlet to a tank or well. In extreme conditions,
or where this is not possible, the transmitter may be mounted in a vented
stilling tube provided that the inside measurement of the stilling tube is at
least 4 in. (100 mm) and is smooth and free from joints or protrusions. It is
important that the bottom of the stilling tube stays covered to prevent the
ingress of foams.
b) Avoid mounting the transmitter directly over any inlet stream.
c) Liquid surface turbulence is not normally a problem unless it is excessive.
The effects of turbulence are minor, but excessive turbulence can be dealt
with by fine-tuning the transmitter on site, if necessary.
In-tank Effects Guidelines:
a) Stirrers or agitators can cause a vortex. Mount the transmitter off-center of
any vortex to maximize the return echo.
b) If stirrer blades become uncovered, they create echoes as they pass
through the ultrasonic beam. The transmitter can learn to ignore these
false echoes (see “Learn About Echoes From False Targets (The
3102/3105)“ on page 5-12.
c) In non-linear tanks with rounded or conical bottoms, mount the transmitter
off-center. If needed, a perforated reflector plate can be installed on the
tank bottom directly under the transmitter center line to ensure a
satisfactory return echo.
d) Avoid mounting the transmitter directly above pumps because the
transmitter will detect the pump casing as the liquid falls away. If this is not
possible, fine-tuning of the transmitter on site may be required.
