WARNING

Explosions could result in death or serious injury.

Installation of this transmitter in an explosive environment must be in accordance with the appropriate local,
national, and international standards, codes, and practices.

 Before connecting communications in an explosive atmosphere, make sure the instruments in the loop

are installed in accordance with intrinsically safe or non-incendive field wiring practices.

 In an Explosion-Proof/Flame-Proof installation, do not remove the transmitter covers when power is

applied to the unit.

Process leaks may cause harm or result in death.

 To avoid process leaks, only use the o-ring designed to seal with the corresponding flange adapter.

Electrical shock can result in death or serious injury.

 Avoid contact with the leads and the terminals. High voltage that may be present on leads can cause

electrical shock.

1.3 Bolting considerations

If the transmitter installation requires assembly of the process flanges, manifolds,
or flange adapters, follow these assembly guidelines to ensure a tight seal for
optimal performance characteristics of the transmitters. Use only bolts supplied
with the transmitter or sold by Emerson as spare parts. Figure 2 illustrates
common transmitter assemblies with the bolt length required for proper
transmitter assembly.

June 2016

A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and optional flange adapters
C. Transmitter with traditional flange and optional flange adapters
D. Transmitter with coplanar flange and optional manifold and flange adapters

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the markings on the head of the bolt and referencing Tabl e 1 . If bolt material is
not shown in Tabl e 1 , contact the local Emerson Process Management
representative for more information.

Use the following bolt installation procedure:

1. Carbon steel bolts do not require lubrication and the stainless steel bolts are
coated with a lubricant to ease installation. However, no additional lubricant
should be applied when installing either type of bolt.

2. Finger-tighten the bolts.

3. Torque the bolts to the initial torque value using a crossing pattern. See

Table 1 for initial torque value.

4. Torque the bolts to the final torque value using the same crossing pattern. See

Table 1 for final torque value.

5. Verify that the flange bolts are protruding through the isolator plate before
applying pressure.

1.4 O-rings with flange adapters

WARNING

Failure to install proper flange adapter O-rings may cause process leaks, which can result in death or
serious injury. The two flange adapters are distinguished by unique O-ring grooves. Only use the O-ring
that is designed for its specific flange adapter, as shown below:

Whenever the flanges or adapters are removed, visually inspect the o-rings. Replace them if there are any
signs of damage, such as nicks or cuts. If you replace the o-rings, re-torque the flange bolts and alignment
screws after installation to compensate for seating of the PTFE o-ring.

Quick Start Guide

2.0 Connect wiring

Use the following steps to wire the transmitter:

1. Remove the electronics housing cover on the side marked FIELD TERMINALS.

2. Wire the RTD.

Temperature is input through the Resistance Temperature Detector (RTD)
probe and circuitry. The Rosemount 3095FC provides terminations for a 2- or
3-wire 100-ohm platinum RTD with a IEC 751 curve. The RTD has an alpha (α)
equal to 0.00385.

The RTD mounts directly to the piping using a thermowell. RTD wires should
be protected by a metal sheath or by a conduit connected to a conduit wiring
fitting on the enclosure. The RTD wires connect to the three screw terminals
designated “RTD” on the Termination Board.

Wiring between the RTD and Rosemount 3095FC should be shielded wire,
with the shield grounded only at one end to prevent ground loops. Ground
loops cause RTD input signal errors.

Table 2 displays the RTD terminal connections for the various RTD probes.

Ter mi nal Designation 3-wire RTD 2-wire RTD

RTD + Signal positive input RTD + RTD +

RTD RET Return reference RTD RET RTD RET

3. Wire the power supply.

The terminals are labeled CHG+ for positive power connection and CHG- for
negative power connection on a label on the termination board. These
connections provide the input voltage and power for the battery charging
circuit. The maximum voltage that can be applied to the CHG+/CHG­terminals is 28 Volts dc.

1 CHG+ Battery 8.0 to 28 V Power

2 CHG- Battery Common

4. Communications wiring

The Local Operator Interface (LOI) port provides direct communications
between the Rosemount 3095FC and the serial port of an operator interface
device, such as an IBM compatible PC using an EIA-232 (RS-232) link. The
interface allows access to the Rosemount 3095FC (using Rosemount User
Interface Software) for configuration and transfer of stored data.

Software. One end of the cable (a 9-pin, D-shell, female connector) plugs into
a serial communications port on the PC. The other end of the cable plugs into
the Rosemount 3095FC.

3.0 Set jumpers and apply power

To prevent unnecessary battery drainage, the Rosemount 3095FC is delivered
with the reset jumper in the OFF position. To apply power to the Rosemount
3095FC:

1. Complete the necessary wiring.

2. Unscrew the front end cap cover (LCD display end).

3. Place the power jumper in the ON position. The jumper is located on the LCD
display (if installed) or at J1 on the Battery Charger Board.

4. Screw the front-end cap cover (LCD display end).

After the Rosemount 3095FC completes start-up diagnostics (RAM and other
internal checks), the optional LCD display shows the date and time to indicate
that the Rosemount 3095FC completed a valid reset sequence.

Quick Start Guide

4.0 Establish communication

1. Open the Rosemount 3095FC User Interface Software

2. Enter the factory-assigned User ID and Password:
User ID: LOI
Password: 1000

3. Select Direct Connect, located on the software toolbar.

5.0 Verify configuration

1. Select Device > Clock from the menu tab.

2. Verify the correct time and date for the transmitter’s memory logs, and click
OK to exit the screen.

3. Select Device > Information from the menu tab.

4. Verify the correct station name, address number, group number, and contract
hour. Select OK to exit the screen.

5. Select Meter > Set Up from the menu tab.

6. Verify values of pipe and orifice diameter by selecting the General tab.

7. Select Inputs from the top of the screen and verify the correct range and units
of measure for the analog inputs.

8. Select the Gas Quality tab from the top of the screen and verify the correct gas
composition for your process.

9. Select the Advanced tab from the top of the screen. Verify the correct values
for FPV method, units of measure, and all geographical parameters. Select OK
to exit the screen.

6.0 Trim the transmitter

Note

Transmitters are shipped from Emerson™ Process Management, Emerson fully calibrated
per request or by the factory default of full scale.

6.1 Zero trim

A zero trim is a single-point adjustment used for compensating mounting
position effects. When performing a zero trim, ensure the low side block valve is
closed, the equalize valve is open, the high side block valve is open, and all wet
legs are filled to the correct level.

To check or adjust for zero shift, leave the sensor by-pass valve open (to simulate
a no-flow condition), with either line pressure or a normal operating SP from the
calibrator applied to the sensor. This applies the same pressure to both sides of
the DP diaphragm to give a zero DP reading.

Quick Start Guide

Perform the following steps:

1. Connect the Rosemount User Interface Software to the Rosemount 3095FC
and run the calibration procedure.

2. Select Meter>Calibration >Freeze.

3. Under the Diff Press input, click Zero Shift to open the Set Zero Shift window.

4. Verify Reading to determine if a Zero Sift correction is required.

5. If the reading is not zero, select Set Zero Shift to adjust the Zero and select
Done. If the reading is zero, select Done.

6. Select Done to close the calibration window and cancel the freeze values to
begin using live readings for the flow calculations.

7. Once the zero trim is complete, verify that the high side block valve is open,
close the equalize valve tightly, then open the low side block valve.
