Rosemount Model 3095FT HART Flow Transmitter
SYSTEM DESCRIPTION
The Model 3095FT HART Flow Transmitter is an advanced compact
electronic gas measurement (EGM) device. Where traditional
transmitters measure just one process variable, the Model 3095FT
measures three variables simultaneously: differential pressure,
absolute pressure, and process temperature. The Multivariable
™
module incorporates a high-accuracy capacitance sensor for measuring
differential pressure, a high-accuracy piezoresistive sensor for
measuring absolute pressure, and a four-wire RTD input for process
temperature measurement. In addition, the sensor electronics convert
the process variables directly into digital format for further correction
and compensation within the sensor module.
The Model 3095FT performs American Gas Association flow
calculations per A.G.A. Report No. 3 (API MPMS Chapter 14.3 — GPA
8185-92) and A.G.A. Report No. 8 (API MPMS Chapter 14.2), and stores
all relevant data in nonvolatile memory in accordance with American
Petroleum Institute electronic flow measurement standards (API Manual of Petroleum Measurement Standards, Chapter 21.1,
“Electronic Gas Measurement”). The three process variables and the
®
flow rate are available at all times via the HART
protocol on a single
two-wire system.
Configuring the Model 3095FT is accomplished by using the Model
3095FT User Interface Software, an easy-to-use software package
which runs on a DOS-based personal computer (386 and above) running
Microsoft
®
Windows.® This software package can include a modem to
connect a computer to the Model 3095FT, and provides both
configuration capabilities and retrieval capabilities for the Model
3095FT logged data.

Switches
1. Place the shipping containers on a secure bench and open them,
taking care not to damage the contents.
2. Review the packing list to verify that all equipment was received.
3. Inspect the equipment and report any shipping damage to the
carrier.
Before mounting the Model 3095FT in the field, the flow transmitter
should be configured on the bench using a personal computer and the
Model 3095FT User Interface Software.
This software provides advanced configuration capabilities, including
flow parameters (such as meter tube bore, orifice bore, orifice plate
material, contract hour, DP cut-off, and static pressure type), gas
properties (for example, A.G.A. 8 GrHvCO2), and audit trail
configuration (such as configuration log, event log, and hourly and daily
quantity transaction record).
After bench configuration, the Model 3095FT may be bench calibrated.
These procedures include absolute pressure sensor offset and slope
trim, and differential pressure sensor offset and slope trim.
For information concerning Model 3095FT bench configuration and
Model 3095FT bench calibration, see pages 4-10 and 4-11.
Once the transmitter has been configured, the configuration data can
be protected by moving the write protection (WP) switch. When this
switch is set to “ON,” the transmitter will not allow any changes to its
configuration memory, and will not allow the transmitter to be placed
into any Maintenance Mode.
The real-time clock switch (RTC) determines whether the battery
powers the real-time clock during power outages. This switch should
always be set to “ON” because the real-time clock battery is required for
maintaining the internal Model 3095FT clock if transmitter power is
interrupted.
When shipped from the factory, the write protect switch is set to “OFF,”
and the real-time clock switch is set to “ON” (see Figure 2-4).
NOTE
Setting the real-time clock switch to “OFF” may result in inaccurate
time-stamps if power to the Model 3095FT is interrupted. Therefore,
always set the real-time clock switch to “ON.”

GENERAL
CONSIDERATIONS
MECHANICAL
CONSIDERATIONS
The accuracy of a flow or pressure measurement depends to a great
extent on proper installation of the transmitter and impulse piping. The
piping between the process and transmitter must accurately transmit
process pressure to the transmitter. Mount the flow transmitter close to
the process and use a minimum of impulse piping to achieve best
accuracy. Keep in mind, however, the need for easy access, safety of
personnel, practical field calibration, and a suitable transmitter
environment. In general, install the transmitter so as to minimize
vibration, shock, and temperature fluctuations.
For installations using the Remote Power Supply option, be sure the
mounting location is in an area that allows the Remote Power Supply to
receive full sun.
The Rosemount Model 3095FT may be panel-mounted, wall-mounted,
or attached to a two-inch pipe with an optional mounting bracket.
Figure 2-5 illustrates Model 3095FT mounting configurations.Figure
2-6 shows the transmitter dimensions, and Figure 2-6 illustrates
example installations.
NOTE
When the transmitter is oriented on its side, the Coplanar
™
flange may
be mounted to ensure proper venting or draining. Mount the flange as
shown in Figure 2-6 so that the drain/vent connections are on the
bottom half of the flange.

Rosemount Model 3095FT HART Flow Transmitter
Taps
Impulse Piping
For gas flow measurement, place taps in the top or side of the line and
mount the transmitter beside or above the taps so liquid will drain into
the process line.
The piping between the process and the transmitter must accurately
transfer the pressure to obtain accurate measurements. In this
pressure transfer, three possible sources of error can occur: leaks,
friction loss, and liquid in the impulse line.
Consider the following general rules in determining flow transmitter
location and placement of impulse piping:
• Keep impulse piping as short as possible.
• Slope the impulse piping at least one inch per foot (8 centimeters
per meter) downward from the transmitter toward the process
connection.
• Avoid low points in gas lines.
• Use impulse piping large enough to avoid friction effects and
prevent blockage.
• Keep corrosive or hot (above 185 °F (85 °C)) process material out
of direct contact with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Avoid conditions that might allow process fluid to freeze within
the process flange.

Process Considerations
Wiring connections are made through the conduit openings on the top
side of the housing. The field terminal side is marked on the electronics
housing. Mount the transmitter so that the terminal side is accessible.
A 0.75-inch clearance is required for cover removal. Install a conduit
plug on the unused side of the conduit opening.
The circuit compartment should not routinely need to be opened when
the unit is in service; however, provide 0.75 inches clearance if possible
to allow access. A 3-inch clearance is required for cover removal if a
meter is installed. See Section 3 - Options.

Failure to install proper flange adapter O-rings can cause
process leaks, which can result in death or serious injury.
There are two styles of Rosemount flange adapters, each
requiring a unique O-ring, as shown below. Each flange
adapter is distinguished by its unique groove.

®
When compressed, Teflon
O-rings tend to cold flow, which aids in their
sealing capabilities. Whenever flanges or adapters are removed,
visually inspect the Teflon O-rings. Replace them if there are any signs
of damage, such as nicks or cuts. If they are undamaged, they may be
reused. If the O-rings are replaced, the flange bolts may need to be
retorqued after installation to compensate for cold flow. Refer to the
process sensor body reassembly procedure on page 5-15.

Bolt Installation Guidelines
The following guidelines have been established to ensure a tight flange,
adapter, or manifold seal. Use only bolts supplied with the transmitter
or sold by Rosemount Inc. as a spare part to the Model 3095FT
transmitter.
The Model 3095FT is shipped with the Coplanar flange installed with
four 1.75-inch flange bolts. The following bolts also are supplied to
facilitate other mounting configurations:
• Four 2.25-inch manifold/flange bolts for mounting the Coplanar
flange on a three-valve manifold. In this configuration, the 1.75inch bolts may be used to mount the flange adapters to the
process connection side of the manifold.
• (Optional) If flange adapters are ordered, four 2.88-inch flange/
adapter bolts for mounting the flange adapters to the Coplanar
flange.
Figure 2-7 shows the optional mounting bracket and mounting
configurations. Figure 2-8 shows mounting bolts and bolting
configuration for the Model 3095FT with the coplanar flange.
Stainless steel bolts supplied by Rosemount Inc. are coated with a
lubricant to ease installation. Carbon steel bolts do not require
lubrication. No additional lubricant should be applied when installing

ELECTRICAL
CONSIDERATION
Power Supply
The signal terminals are located in a compartment of the electronics
housing separate from the transmitter electronics. Figure 2-9
illustrates power supply load limitations for the transmitter.
The dc power supply should provide power with less than 2% ripple.
The total resistance load is the sum of the resistance of the signal leads
and the load resistance of the controller, indicator, and related pieces.
Note that the resistance of intrinsic safety barriers, if used, must be
included.
NOTE
A minimum loop resistance of 250 ohms is required to communicate
with a personal computer. With 250 ohms of loop resistance, the
transmitter requires a minimum of 11.0 volts.
If a single power supply is used to power more than one Model 3095FT
transmitter, the power supply used, and circuitry common to the
transmitters, should not have more than 20 ohms of impedance at
1200 Hz.
If the Remote Power Supply enclosure is installed, a 250 ohm resistor is
factory installed — do not add additional loop resistance.

Inductive-based transient protectors, including the
Rosemount Model 470, can adversely affect the output of
the Model 3095FT. Do not use the Model 470 for transient
protection with the Model 3095FT. If transient protection is
desired, install the Transient Protection Terminal Block as
explained on Page 3-5.

FIELD INSTALLATION
PROCEDURE
1. Review Installation
Considerations
2. Mount Transmitter and
Install Bolts
For explosion-proof installations, installation location must
be made in accordance with Rosemount drawing 030951025 or 03095-1024.
For instrinsically safe installations, installation location must
be made in accordance with Rosemount drawings
03095-1020 and 03095-1030; or 03095-1021 and
03095-1031.
1. Review the installation considerations described on pages 2-6
through 2-15 in this chapter to determine the location for the
Model 3095FT. If the installation includes the Remote Power
Supply, also review the sunlight considerations described on page
3-8.
2. Mount the Model 3095FT in the desired location, and install
flange or flange/adaptor bolts.
TABLE 2-2. Bolt Installation Torque
Value s.
3. Make Process
Connections
Only use bolts supplied with the Model 3095FT or sold by
Rosemount Inc. as a spare part to the Model 3095FT.
Unauthorized parts can affect product performance and
may render the instrument dangerous.
a.Finger-tighten the bolts.
b.Torque the bolts to the initial torque value using a cross-pattern
(see Table 2-2).
c. Torque the bolts to the final torque value using the same cross-
pattern.
Bolt Material Initial TorqueValue Final Torque Value
Carbon Steel (CS) 300 in-lb 650 in-lb
Stainless Steel (SST) 150 in-lb 300 in-lb
When installing the transmitter to one of the mounting brackets, torque
the mounting bracket bolts to 125 in-lb.
3. Connect the transmitter to the process.
2-16
Process leaks can cause death or serious injury. All four
flange bolts must be installed and tight before applying
pressure, or process leakage will result. When properly
installed, the flange bolts will protrude through the top of the
module housing. Attempting to remove the flange bolts
while the transmitter is in service will result in leakage of the
process fluid.

NOTES
• Do not run field wiring in conduit or open trays with other power
wiring, or near heavy electrical equipment.
• Field wiring need not be shielded, but twisted pairs should be used for
best results.
• To ensure communication, wiring should be 24 AWG or larger
and not exceed 5,000 feet (1,500 meters).
• For connections in ambient temperatures above 140 °F (60 °C), use
wiring rated for at least 194 °F (90 °C).
Incorrect field wiring connections may damage the Model
3095FT. Do not connect field wiring to the “TEST +”
terminals.
