Custom gas

About this task

The custom gas option should be used for fluids not in the database such as proprietary
fluids or gas mixtures. To properly calculate the fluid properties, the compressibility factor
or density needs to be entered at specific pressure and temperature values based on the
operating ranges entered by the user. The pressure and temperature values may be edited
as needed. The editable values are shown in fields with white backgrounds. For best
performance, it is recommended that, whenever possible, the compressibility or density
values be entered at the suggested pressure and temperature values.

To ease entering the compressibility/density or viscosity values, data can be copied from a
spreadsheet and pasted into the grid. The recommended process is to copy the pressure
and temperature values from the table on the Engineering Assistant screen to assist in
computing the density or compressibility values. Once the compressibility or density
values are computed, they may then be copied from the spreadsheet and pasted into the
grid on the Custom Gas Fluid Properties tab.

2.6.2 Alarm and saturation

The Rosemount 3051SMV automatically and continuously performs self-diagnostic
routines. If the self-diagnostic routines detect a failure, the transmitter drives the output
to the configured alarm value. The transmitter will also drive the output to configured
saturation values if the primary variable goes outside the 4–20 mA range values.

The alarm and saturation settings can be configured using Engineering Assistant, AMS
Device Manager, or a Field Communicator. See Alarm and saturation level configuration
for more information. The alarm direction can be configured using the hardware switch on
the feature board. See Configure security (write protect) for more information on the
hardware switch.

The Rosemount 3051SMV has three options for alarm and saturation levels:

• Rosemount (Standard), see Table 2-4

• NAMUR, see Table 2-5

• Custom (user-defined), see Table 2-6

Table 2-4: Rosemount (Standard) Alarm and Saturation Values

The following limitations exist for custom levels:

• Low alarm level must be less than the low saturation level

• High alarm level must be higher than the high saturation level

• Alarm and saturation levels must be separated by at least 0.1 mA

Alarm level verification

The transmitter alarm level should be verified before returning the transmitter to service if
alarm and saturation levels are changed.

This feature is also useful in testing the reaction of the control system to a transmitter in
an alarm state. To verify the transmitter alarm values, perform a loop test and set the
transmitter output to the alarm value (see Alarm and saturation and Analog output loop

test).

Variable saturation behavior

The analog output of the Rosemount 3051SMV may respond differently based on which
measurement goes outside the sensor limits. This response will also depend on the device
configuration. Table 2-7 lists the behaviors of the analog output under different
conditions.

Burst mode

When Burst Mode Enable is set to on, the Rosemount 3051SMV sends up to four HART
variables to the control system without the control system polling for information from
the transmitter.

When operating with Burst Mode Enable set to on, the transmitter will continue to output
a 4–20 mA analog signal. Because the HART protocol features simultaneous digital and
analog data transmission, the analog value can drive other equipment in the loop while
the control system is receiving the digital information. Burst mode applies only to the
transmission of dynamic data (process variables in engineering units, primary variable in
percent of range, and/or analog output), and does not affect the way other transmitter
data is accessed.

Access to information that is not burst can be obtained through the normal poll/response
method of HART communication. A Field Communicator, AMS Device Manager,
Engineering Assistant, or the control system may request any of the information that is
normally available while the transmitter is in burst mode.

The Rosemount 3051SMV is set to address zero (0) at the factory, which allows operation
in the standard point-to-point manner with a 4–20 mA output signal. To activate
multidrop communication, the transmitter address must be changed to 1–15 for HART 5
hosts or 1–63 for HART 6 hosts. This change deactivates the 4–20 mA analog output,
sending it to a fixed value of 4 mA. It also disables the failure alarm signal, which is
controlled by the HI/LO alarm switch position on the feature board. Failure signals in
multidropped transmitters are communicated through HART messages.

Transfer function (direct process variable output feature board only)

The Rosemount 3051SMV with direct process variable output feature board has two
analog output settings: Linear and Square Root. Activate the square root output option to
make analog output proportional to flow. As input approaches zero, the Rosemount
3051SMV automatically switches to linear output in order to ensure a smooth, stable
output near zero (see Figure 2-41).

From 0 to 0.6 percent of the ranged pressure input, the slope of the curve is unity (y = x).
This allows accurate calibration near zero. Greater slopes would cause large changes in
output (for small changes at input). From 0.6 to 0.8 percent, curve slope equals 41.72 (y =

41.72x) to achieve continuous transition from linear to square root at the transition point.

Note

Do not set both the analog output of the device and the control system to square root.

3.3 Installation considerations

3.3.1 General

Measurement performance depends upon proper installation of the transmitter, impulse
piping, and process temperature sensor. Mount the transmitter close to the process and
use minimum piping to achieve best performance. Also, consider the need for easy access,
personnel safety, practical field calibration, and a suitable transmitter environment. Install
the transmitter to minimize vibration, shock, and temperature fluctuation.

Note

Install the enclosed pipe plug (found in the box) in the unused conduit opening if optional
process temperature input is not used. For proper straight and tapered thread
engagement requirements, see the appropriate approvals drawings in Product

Certifications.

For material compatibility considerations, see the Material Selection Technical Note.

3.3.2

Mechanical

For steam service or for applications with process temperatures greater than the limits of
the transmitter, do not blow down impulse piping through the transmitter. Flush lines
with the blocking valves closed and refill lines with water before resuming measurement.

When the transmitter is mounted on its side, position the coplanar flange to ensure proper
venting or draining. Mount the flange as shown in Bolt installation, keeping drain/vent
connections on the bottom for gas service and on the top for liquid service.

3.4 Installation procedures

3.4.1 Configure security (write protect)

About this task

Changes to the transmitter configuration data can be prevented with the security (write
protect) switch located on the feature board. See Figure 3-1 for the location of the switch.
Position the switch in the ON position to prevent accidental or deliberate change of
configuration data.

If the transmitter write protection switch is in the ON position, the transmitter will not
accept any “writes” to its memory. Configuration changes, such as digital trim and
reranging, cannot take place when the transmitter security is on.

To reposition the switches, follow the procedure described below:

Procedure

1. Do not remove the transmitter covers in explosive atmospheres when the circuit is

live. If the transmitter is live, set the loop to manual and remove power.

2. Remove the housing cover opposite the field terminal side of the housing.

3. To reposition the switches as desired, slide the security and alarm switches into the

preferred position using a small screwdriver. See Figure 3-1.

3.4.5 Process connections

About this task

The Rosemount 3051SMV flange process connection size is 1/4–18 NPT. Flange adapters
with a 1/4–18 NPT to 1/2–14 NPT connection are available with the D2 option. Use a plant­approved lubricant or sealant when making the process connections. The process
connections on the transmitter flange are on 2 1/8-in. (54 mm) centers to allow direct
mounting to a 3- or 5-valve manifold. Rotate one or both of the flange adapters to attain
connection centers of 2-in. (51 mm), 2 1/8-in. (54 mm), or 2 1/4-in. (57 mm).

CAUTION

Install and tighten all four flange bolts before applying pressure to avoid leakage. When

WARNING

When compressed, PTFE O-rings tend to cold flow, which aids in their sealing capabilities.

Note

You should replace PTFE O-rings if you remove the flange adapter.

Impulse piping considerations

The piping between the process and the transmitter must accurately transfer the pressure
to obtain accurate measurements. There are many possible sources of error: pressure
transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line,
liquid in a gas line, density variations between the legs, and plugged impulse piping.

The best location for the transmitter in relation to the process pipe depends on the
process itself. Use the following guidelines to determine transmitter location and
placement of impulse piping:

• Keep impulse piping as short as possible.

Emerson.com/Rosemount 83

Installation Reference Manual

October 2018 00809-0100-4803

• For liquid service, slope the impulse piping at least 1 in. per ft. (8 cm per m) upward

from the transmitter toward the process connection.

• For gas service, slope the impulse piping at least 1 in. per ft. (8 cm per m) downward

from the transmitter toward the process connection.

• Avoid high points in liquid lines and low points in gas lines.

• Make sure both impulse legs are the same temperature.

• Use impulse piping large enough to avoid friction effects and blockage.

• Vent all gas from liquid piping legs.

• When using a sealing fluid, fill both piping legs to the same level.

• When purging, make the purge connection close to the process taps and purge

through equal lengths of the same size pipe. Avoid purging through the transmitter.

• Keep corrosive or hot, above 250 °F (121 °C), process material out of direct contact

with the SuperModule process connection and flanges.

• Prevent sediment deposits in the impulse piping.

• Keep the liquid head balanced on both legs of the impulse piping.

Note

Take necessary steps to prevent process fluid from freezing within the process flange to
avoid damage to the transmitter.

3.4.6

Note

Verify transmitter zero point after installation. To reset zero point, refer to .

Connect wiring and power up

It is recommended to use twisted pair wiring. To ensure proper communication, use 24 to
14 AWG wire, and do not exceed 5000 ft. (1500 m).

About this task

3.5 Rosemount 305 and 304 Manifolds

The Rosemount 305 Integral Manifold is available in two designs: coplanar and traditional.
The traditional Rosemount 305 can be mounted to most primary elements with mounting
adapters.

Rosemount 305 Integral Coplanar Rosemount 305 Integral Traditional

The Rosemount 304 comes in two basic styles: traditional (flange X flange and flange X
pipe) and wafer. The Rosemount 304 Traditional Manifold comes in 2-, 3-, and 5-valve
configurations. The Rosemount 304 Wafer Manifold comes in 3- and 5-valve
configurations.

3.5.1 Install Rosemount™ 305 Integral Manifold

To install a Rosemount 305 Integral Manifold to a Rosemount 3051 Transmitter:

Procedure

1. Inspect the PTFE sensor module O-rings.

You may reuse undamaged O-rings. If the O-rings are damaged (if they have nicks
or cuts, for example), replace with O-rings designed for Rosemount transmitters.

Important

If replacing the O-rings, take care not to scratch or deface the O-ring grooves or the
surface of the isolating diaphragm while you remove the damaged O-rings.

2. Install the Integral Manifold on the sensor module. Use the four 2.25-in. manifold

bolts for alignment. Finger tighten the bolts; then tighten the bolts incrementally in
a cross pattern as seen in Figure 3-16 to final torque value.

See Flange bolts for complete bolt installation information and torque values. When
fully tightened, the bolts should extend through the top of the sensor
module housing.

3. If you have replaced the PTFE sensor module O-rings, re-tighten the flange bolts

after installation to compensate for cold flow of the O-rings.

To install a Rosemount 304 Conventional Manifold to a Rosemount 3051 Transmitter:

About this task

See Safety messages for complete warning information.

Procedure

1. Align the Conventional Manifold with the transmitter flange. Use the four manifold

bolts for alignment.

2. Finger tighten the bolts; then tighten the bolts incrementally in a cross pattern to

final torque value.
See Flange bolts for complete bolt installation information and torque values. When

fully tightened, the bolts should extend through the top of the sensor module
housing.

3. Leak-check assembly to maximum pressure range of transmitter.

Manifold operation

WARNING

Improper installation or operation of manifolds may result in process leaks, which may
cause death or serious injury.

Always perform a zero trim on the transmitter/manifold assembly after installation to
eliminate any shift due to mounting effects. See Sensor trim overview.
