Warnings

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. Please review the approvals section of the Rosemount 2051 Reference Manual for any restrictions associated with a safe installation.

•Before connecting a HART® communicator in an explosive atmosphere, ensure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

•In an Explosion-Proof/Flameproof installation, do not remove the transmitter covers when power is applied to the unit.

Process leaks may cause harm or result in death.

•Install and tighten process connectors before applying pressure. Electrical shock can result in death or serious injury.

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

WARNING

Electrical shock can result in death or serious injury.

•Avoid contact with the leads and terminals. Process leaks could result in death or serious injury.

•Install and tighten all four flange bolts before applying pressure.

•Do not attempt to loosen or remove flange bolts while the transmitter is in service.

Replacement equipment or spare parts not approved by Emerson Process Management for use as spare parts could reduce the pressure retaining capabilities of the transmitter and may render the instrument dangerous.

•Use only bolts supplied or sold by Emerson Process Management as spare parts.

•Refer to page 208 for a complete list of spare parts.

Improper assembly of manifolds to traditional flange can damage sensor module.

•For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not contact sensor module housing.

2.4Flow configuration

2.4.1Rosemount 3051SMV Engineering Assistant 6.3 or later

The Rosemount 3051SMV Engineering Assistant is designed to guide the user through the setup of the flow configuration of a Rosemount 3051SMV. The flow configuration screens allow the user to specify the fluid, operating conditions, and information about the primary element including the inside pipe diameter. This information will be used by the Rosemount 3051SMV Engineering Assistant to create the flow configuration parameters that can be sent to the transmitter or saved for future use.

NOTICE

To ensure correct operation, download the most current version of the Engineering Assistant software at Emerson.com/en-us/catalog/rosemount-engineering-assistant-6.

Figure 2-2 shows the path in which the Rosemount 3051SMV Engineering Assistant will guide the user through a flow configuration. If a natural gas, custom liquid, or custom gas option is chosen, an extra screen will be provided to specify the gas composition or fluid properties.

6.If necessary, select a Primary Element Material from the drop-down menu.

7.A calibration factor may be entered if a calibrated primary element is being used.

Note

A Joule-Thomson Coefficient can be enabled to compensate for the difference in process temperature between the orifice plate location and the process temperature measurement point. The Joule-Thomson Coefficient is available with ASME MFC-3M-2 (2004) or ISO 5167-2.2003 (E) orifice plates used with Database Gases, Superheated Steam, or AGA DCM/ISO Molar Composition Natural Gas. For more information on the Joule-Thomson Coefficient, reference the appropriate orifice plate standard.

5.In the Available Components window, select the required components and move them into the Selected Components window using the >> button. The << button moves the components back to the Available Components window. The Clear button moves all components back to the Available Components window.

6.After all required components are in the Selected Components window, begin assigning the percent composition of each component in the Mole % column.

Note

These percent composition values should add to 100 percent. If they do not, select the Normalize button. This will adjust the mole percentages proportionally to a total of 100 percent.

7.Enter the Nominal Operating Pressure, then the Nominal Operating Temperature as the entry blanks become available. Engineering Assistant will automatically fill in suggested operating ranges. These values may be edited by the user.

Note

In order to comply with the AGA requirements the calculation accuracy must be within ±50 ppm (±0.005%). This is stated in AGA Report No. 3, Part 4, Section 4.3.1. The pressure and temperature operating ranges will be autofilled to comply with the standard.

8.Select Next >. This will bring the user to the Fluid Properties tab.

9.Proceed with the steps in Fluid properties.

(1)Reference conditions for the relative density are 60 °F (15.56 °C) and 14.73 psia (101.56 kPa).

(2)Reference conditions for the molar gross heating value are 60 °F (15.56 °C) and 14.73 psia (101.56 kPa) and reference conditions for molar density are 60 °F (15.56 °C) and 14.73 psia (101.56 kPa).

5.If appropriate, enter the optional data for the Natural Gas Characterization Method that was selected in Step 2. Optional data for each method is listed in Table 2-3.

6.Enter the Nominal Operating Pressure, then the Nominal Operating Temperature as the entry blanks come available. Engineering Assistant will automatically fill in suggested operating ranges. Note that these values may be edited by the user.

7.Select Next. This will open the Fluid Properties tab.

8.Proceed with the steps in Fluid properties.

Ideal gas

The ideal gas option should be used when the fluid behavior can be modeled by the ideal gas law. This option uses a modified version of the ideal gas law with a constant value of compressibility. The default value for compressibility is 1.00 but it may be edited by the user. To use an ideal gas enter in the operating pressure and temperature followed by either the density, specific gravity, or molecular weight.

Procedure

1.Expand the GAS category.

2.Select the Ideal Gas option.

3.Enter the Nominal Operating Pressure and Temperature Ranges. Engineering Assistant will use these ranges to identify the pressure and temperature values at which the fluid properties are required.

For the ideal gas being used the nominal density, specific gravity, or molecular weight must now be entered using the drop-down menu. Once these are entered the other data entry fields, compressibility and viscosity, are enabled as shown on Figure 2-14.

Figure 2-14: Fluid Selection Ideal Gas

4.Adjust the compressibility and viscosity to fit the ideal gas of the process.

5.Select Next to proceed to the Fluid Properties tab.

Note

The Fluid Properties tab is an optional step and is not required to complete a flow configuration. The Fluid Properties tab for the database gas air is shown in Figure 2-15. The user may view the properties of the chosen fluid. The fluid properties are initially shown at nominal conditions. To view density, compressibility, and viscosity of the selected fluid at other pressure and temperature values, enter a Pressure and Temperature and select Calculate. Changing the pressure and temperature values on the Fluid Properties tab does not affect the flow configuration.

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.

Procedure

1.Expand the Gas category.

2.Select the Custom Gas option.

3.Enter the Nominal Operating Pressure and Temperature Ranges. Engineering Assistant will use these ranges to identify the pressure and temperature values at which the fluid properties are required.

4.Select Next to proceed to the Custom Gas Fluid Properties tab.
