2.1 Introduction to the transmitters
The Rosemount 3107 and Rosemount 3108 are sealed 4–20 mA loop-powered liquid level
transmitters, and are designed for use in waste water and effluent treatment plant applications.
The 3108 is MCERTS certified for open flow channel applications.
These rugged UPVC transmitters are certified Intrinsically Safe for use in Zone 0 areas, and
factory fitted with up to 164 ft. (50 m) of two-core cable for simple low cost installation in
sumps, wet-wells and over open channel flow structures.
December 2014
The transmitters can be connected directly to a plant control system, or used with a Rosemount
3490 Series Control Unit for programmable control functionality.
Note
The Rosemount 3490 Series Control Unit software must be version 3.40 or later.

2.2 Theory of operation
The level transmitter is designed to be mounted above a liquid (Figure 2-1 on page 3), and uses
ultrasonic pulses to continuously measure the distance to the liquid surface. The electronics
calculate distance to the liquid level using the time delay between transmitting and receiving
signals.
When programmed with the bottom reference of the application – usually the bottom of a tank
– the transmitter calculates the liquid depth (level), and outputs the result as a 4–20 mA and
HART signal.
The 3108 and the 3107 can calculate contents (volume) or open channel flow when
programmed with further application information, and outputs the result as a 4–20 mA and
HART signal.
2.3 Components of the transmitter
Reference Manual
00809-0200-4840, Rev BA
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.

2.4 System architecture
The Rosemount 3107 and 3108 are loop-powered which means they use the same two wires for
both power supply and output signal.
The transmitter can be connected to any suitable direct current (dc) power source using the
factory-fitted two-core, shielded cable.
The output is a 4–20mA analog signal and a digital HART signal.
Note
It is possible to use the multidrop function with the HART protocol (see Figure 2-3). In
this case, communication is restricted to digital since the current is fixed to 4 mA.
The transmitters can easily be configured by using a Rosemount 3490 Series Control Unit.
Alternatively, a Field Communicator, or a PC with AMS
software, can be used to configure the transmitter.
Note
The Rosemount 3490 Control Unit software must be version 3.40 or later.

3.2 Considerations before installation
The Rosemount 3107 and 3108 may be used for level and volume measurement in open or
closed tanks, or open channel flow measurement.
The transmitter must be installed in a location 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.
It is important to correctly position the transmitter for reliable ultrasonic level measurement.
For maximum accuracy and stability of the level measurement reading, the transmitter should
always be shrouded from direct sunlight and radiated heat.
The transmitter may be site-tuned to deal with most application conditions, but it is
recommended that the following guidelines be adopted wherever relevant.
3.2.1 Safety considerations
Guidelines
Reference Manual
00809-0200-4841, Rev BA
1. Installation must be carried out by suitably trained personnel in accordance with the
applicable code of practice.
2. 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.
3. The equipment should only be cleaned with a damp cloth. Do not use solvents.
4. 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.
5. The transmitter is Double Insulated, and therefore Protective Earthing is not required.
6. Note that if the equipment is used in a manner not specified by the manufacturer, the
protection afforded by the equipment may be impaired.
7. To ensure electro-magnetic compatibility in any European 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.

3.2.2 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
Figure 3-1. Environmental considerations
Section 3: Installation
December 2014
3.3 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 Figure 3-2 on page 10).
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.

3.3.1 Consider liquid surface conditions
Guidelines
1. 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.
2. Avoid mounting the transmitter directly over any inlet stream.
3. 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.
Section 3: Installation
December 2014
3.3.2 Consider in-tank effects
Guidelines
1. Stirrers or agitators can cause a vortex. Mount the transmitter off-center of any vortex
to maximize the return echo.
2. If stirrer blades become uncovered, they create echoes as they pass through the
ultrasonic beam. The transmitter can learn to ignore false echoes (see “Learn false
echo” on page 23).
3. In 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.
4. Avoid detecting pump casings, as the liquid falls away, by not mounting the transmitter
directly above pumps. If this is not possible, fine-tuning of the transmitter on-site may
be required.
3.3.3 Mounting the transmitter above the liquid surface
A 1-in. thread is provided to mount the transmitter. The thread form is either BSPP (G1) or NPT,
and is marked below the mounting thread.
To help installation, flange accessories and bracket kits are available from Emerson Process
Management. The accessory flanges supplied are manufactured from PVC and are a full face
design. Care must be taken when installing to raised face mating flanges on the tank or vessel to
prevent distortion of the PVC flange by over-tightening the bolts. See “Spare parts and
accessories” on page 120 for ordering information.
Section 3: Installation
Note
Never suspend the transmitter by the cable.

Section 3: Installation
December 2014
Bracket mounting
The transmitter is supplied with a purpose made 316 Stainless Steel mounting bracket which
should be used to mount the transmitter over the liquid surface. The bracket is designed to fit
over the threaded neck of the transmitter and is retained by a locknut (see “1-in. NPT/BSPP
bracket kits” on page 117 for dimensions).
Use a chain or wire through the hole provided in the bracket, which is shaped to ensure that the
transmitter will hang perpendicular to the liquid surface. Check that the material of the chain or
wire is corrosion resistant to the liquids and any vapors present.
The bracket may be bolted to a suitable cross member above the liquid surface. Ensure that the
transmitter is perpendicular to the liquid surface to maximise the return echo size.
Note
Check that the maximum liquid level will not enter the 12 in. (0.3 m) blanking zone of

Flange mounting
The instrument (accessory) flanges supplied by Emerson are manufactured from PVC and are a
full face design. Care must be taken when installing to a raised face mating flange on the tank or
vessel to prevent distortion of the PVC flange by over-tightening the bolts. See “Spare parts and
accessories” on page 120 for part numbers.
Mounting from a conduit
The 3107 and the 3108 can be mounted from a conduit using the optional adaptor
(03107-7003-0003 and 03107-7003-1004). See “Spare parts and accessories” on page 120.
3.3.4 Open channel flow installations
There are normally two distinct parts to an open channel flow measurement system; the
primary element (flow structure) and the secondary element (Head measurement instrumentation). For accurate open channel flow measurement, both parts of the system must be correctly
installed. This section explains the important parts of installing the transmitter (secondary
element). The flow structure (primary element) installation can be referenced in the British
(BS3680) or ISO International standards.
Note
The transmitter should be free from a situation where it is likely to 'drown' (refer to the
relevant standard for further information)
The Rosemount 3108 has a factory-fitted Remote Temperature Sensor.
See “Positioning of the remote temperature sensor (3108 only)” on page 14.
For some installations, the use of a calibration device is mandatory. Emerson offers the
Rosemount Head Verification Device (HVD) for this purpose. See “Spare parts and
accessories” on page 120 for further information.

Positioning of the transmitter
The positioning is critical, and should be the correct distance upstream from the flow structure
as stated in the relevant standard for your country. For example, in the ISO standards, the
distance should be four to five times the maximum height of the water (Hmax) for a thin plate
weir, or three to four times Hmax for a flume. For optimum accuracy, position the transmitter’s
front face at a height equal to the sum of the maximum flow depth plus the transmitter
deadband of 12.2 in. (300 mm) plus an extra 2 in. (50 mm).

Positioning of the remote temperature sensor (3108 only)
The Rosemount 3108 transmitter has a factory fitted remote temperature sensor. The
temperature sensor is enclosed in a M8 x 1.5 threaded stainless steel body.
Figure 3-6 and Figure 3-7 on page 15 show two typical arrangements for installing the
temperature sensor in an open or enclosed chamber. The sensor may be installed in a suitable
plastic conduit box and clamped in place using a suitable compression type cable gland.
1. Open weir chamber (Figure 3-6 on page 15)
Mount the remote temperature sensor so that it is representative of the mean air
temperature in the chamber and is in a shaded area away from direct sunlight and solar
radiation.
2. Enclosed or partially covered flume chamber (Figure 3-7 on page 15)
Mount the remote temperature sensor in the approach channel, in a shaded area away
from direct sunlight and solar radiation. In Figure 3-7 on page 15, the sensor is partially
covered by grating which helps prevent solar gain. (Full grating is removed for clarity.)
The temperature sensor should be positioned in the weir chamber or flume approach channel so
the average air temperature can be accurately measured. The temperature sensor must be
protected at all times from direct sunlight and any radiated heat.
In extreme high temperatures, for the best accuracy and stability of level measurement reading,
the transmitter should be shrouded to prevent the incidence of direct sunlight and solar
radiation. If the flow structure permits, mount the transmitter within the flow channel or
chamber.

3.4 Electrical installation
3.4.1 Connecting the transmitter
The Rosemount 3490 Series is a two-wire loop-powered transmitter accepting power supplies
as follows:
12 to 40 Vdc in a non-hazardous area (ordinary location)
12 to 30 Vdc in a hazardous area (classified location)
Note
To comply with the CSA requirements, the transmitters must be powered from a
Rosemount 3490 Series Control Unit or class 2 or separate extra-low voltage (SELV)
source.
Other devices may reset if connecting the transmitter to a multi-drop system while the
loop is powered. De-energize the loop to avoid devices being reset.
Reference Manual
00809-0200-4841, Rev BA
Each transmitter is supplied with a factory-fitted PVC sheathed, two-core, shielded cable for
communications and external power supply connections. There are no cable conduit entries
and no covers to remove. The cable may be cut to length on site or may be extended using a
junction box and suitable extension cable.
See “Wiring to allow HART communication” on page 18 if HART digital communication is
required.
Installation in a non-hazardous area (ordinary location)
The 3107 and the 3108 are suitable for non-hazardous (ordinary location) applications.
To connect the transmitter:
1. Make sure that the power supply is disconnected.
2. Connect the cable wires as shown in Figure 3-8 on page 17, taking note of the required
voltage of 12 to 40 Vdc for non-hazardous (ordinary location) applications.
Installation in a hazardous area (classified location)
The 3107 and the 3108 are suitable for Intrinsically Safe (IS) applications. Appendix B: Product
Certifications has the safety approval information and control drawings.
When the transmitters are used with a Rosemount 3490 Series Control Unit, no additional
safety barriers are required as the control unit output is Intrinsically Safe.
If powering the transmitter from any other source, ensure a suitable Intrinsically Safe (IS) barrier
is fitted in the non-hazardous area. The barrier must be chosen such that its output parameters
Uo, Io and Po are less than Ui, Ii and Pi of the transmitter (see Appendix B: Product Certifications
for the parameter values). In addition, the sum of the capacitance and the inductance of the
transmitter and any extra cable fitted must not exceed the maximum specified for the barrier.
Suitable barriers include the MTL products 706, 706S, 787, and 787S.

3.4.3 Wiring to allow HART communication
If HART communications is required, a 250 Ohm (minimum), 0.25 W load resistor must be
installed in the loop. (See “Load limitations” on page 114).
Note
When the transmitter is used with a Rosemount 3490 Series Control Unit, there is no
need to install an external load resistor in the loop because a suitable resistor is built in
to the control unit.
If the transmitter is being supplied through a safety barrier, ensure the type chosen will pass
HART information.
After the load resistor is installed, a Field Communicator can be connected across the load
resistor, or across the loop at any point downstream of the load resistor. It is the responsibility
of the installer to ensure that any Field Communicator used in the hazardous area is
suitably certified.
Note
Make sure that the instruments in the loop are installed according to intrinsically-safe
field wiring practices and control drawings, when applicable.

3.4.4 Lightning / surge protection and other loop devices
If the area is prone to lightning strikes or voltage surges, a suppressor device may be installed
between the transmitter and the control unit.
If an additional loop-powered device or separately powered device is included in the two-wire
loop, ensure the transmitter receives a minimum voltage of 12 Vdc (see “Load limitations” on
page 114).

4.1 Overview
The Rosemount 3107 and Rosemount 3108 support HART communications, which may be used
to program or interrogate the transmitters from any point on the two-wire loop.
This section contains information on configuring the transmitters using a
Field Communicator, PC with AMS, or Rosemount 3490 Series Control Unit.

The product manual 00809-0100-4841 provides detailed instructions on installation and
operation of the control unit.
A full menu map showing how to access transmitter parameters using the control unit’s menu
system is in Appendix Appendix C: Rosemount 3490 Series Universal Control Unit.
For convenience, the parameter identification numbers (P*** and D***) are used in parameter
headings and descriptions in this configuration section.
When using the control unit, use the Enter ( ) key to start editing a configuration parameter
and then use the arrow keys to change the setting. Changes are confirmed by pressing the Enter
key, or abandoned by pressing the Esc key. Commands e.g. Set As Empty are run using the
Enter () key.
Note
The Rosemount 3490 Control Unit software must be version 3.40 or later.
