Physical access
NOTICE
Unauthorized personnel can potentially cause significant damage and/or misconfiguration of end users' equipment. Protect against all intentional or unintentional unauthorized use.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access to protect users' assets. This is true for all systems used within the facility.

1.2 Safety messages

WARNING
Explosion hazards. Failure to follow these instructions could cause an explosion, resulting in death or serious injury.
• Verify the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Installation of this transmitter in an explosive environment must be in
accordance with the appropriate local, national, and international standards, codes, and practices. Review the approvals documents for any restrictions associated with a safe installation.
• Do not remove transmitter covers or thermocouple (if equipped) in
explosive atmospheres when the circuit is live. Both transmitter covers must be fully engaged to meet explosion-proof requirements.

4 Pre-installation

4.1 Planning

4.1.1 Sizing

To determine the correct meter size for optimal flow meter performance:
• Determine the limits of measuring flow.
• Determine the process conditions so that they are within the stated
requirements for Reynolds number and velocity.
Sizing calculations are required to select the proper flow meter size. These calculations provide pressure loss, accuracy, and minimum and maximum flow rate data to guide in proper selection. Vortex sizing software can be found using the Selection and Sizing tool. The Selection and Sizing tool can be accessed online or downloaded for offline use using this link:
www.Emerson.com/FlowSizing.

4.1.2 Wetted material selection

Ensure that the process fluid is compatible with the meter body wetted materials when specifying the Rosemount 8800D. Corrosion will shorten the life of the meter body. Consult recognized sources of corrosion data or contact Emerson Flow Sales Representative for more information.
Note
If Positive Material Identification (PMI) is required, perform test on a machined surface.

4.1.3 Orientation

The best orientation for the meter depends on the process fluid, environmental factors, and any other nearby equipment.
Vertical installation
Vertical, upward, installation allows upward process liquid flow and is generally preferred. Upward flow ensures that the meter body always remains full and that any solids in the fluid are evenly distributed.
The meter can be mounted in the vertical down position when measuring gas or steam flows. This type of application is strongly discouraged for liquid flows, although it can be done with proper piping design.

A. Liquid or gas flow B. Gas flow
Note
To ensure the meter body remains full, avoid downward vertical liquid flows where back pressure is inadequate.
Horizontal installation
For horizontal installation, the preferred orientation is to have the electronics installed to the side of the pipe. In liquid applications, this helps prevent any entrained air or solids from striking the shedder bar and disrupting the shedding frequency. In gas or steam applications, this helps prevent any entrained liquid (such as condensate) or solids from striking the shedder bar and disrupting the shedding frequency.

Quick Start Guide 9
High-temperature installations
The maximum process temperature for integral electronics is dependent on the ambient temperature where the meter is installed. The electronics must not exceed 185 °F (85 °C).
Figure 4-3 shows combinations of ambient and process temperatures
needed to maintain a housing temperature of less than 185 °F (85 °C).

Note
The indicated limits are for horizontal pipe and vertical meter position, with meter and pipe insulated with 3 in. (77 mm) of ceramic fiber insulation.
Install the meter body so the electronics are positioned to the side of the pipe or below the pipe as shown in Figure 4-4. Insulation may also be required around the pipe to maintain an electronics temperature below 185 °F (85 °C). See Figure 5-2 for special insulation considerations.

4.1.4 Location

Hazardous area
The transmitter has an explosion-proof housing and circuitry suitable for intrinsically safe and non-incendive operation. Individual transmitters are clearly marked with a tag indicating the certifications they carry. For hazardous location installation, including Explosion-proof, Flameproof,or Intrinsic Safety (I.S.), please consult the Emerson 8800 Approval Document 00825-VA00-0001.
Environmental considerations
Avoid excessive heat and vibration to ensure maximum flow meter life. Typical problem areas include high-vibration lines with integrally mounted electronics, warm-climate installations in direct sunlight, and outdoor installations in cold climates.
Although the signal conditioning functions reduce susceptibility to extraneous noise, some environments are more suitable than others. Avoid placing the flow meter or its wiring close to devices that produce high intensity electromagnetic and electrostatic fields. Such devices include electric welding equipment, large electric motors and transformers, and communication transmitters.
Upstream and downstream piping
The meter may be installed with a minimum of ten diameters (D) of straight pipe length upstream and five diameters (D) of straight pipe length downstream.
Quick Start Guide 11
To achieve reference accuracy, straight pipe lengths of 35D upstream and 5D downstream are required. The value of the K-factor may shift up to 0.5% when the upstream straight pipe length is between 10D and 35D. For optional K-factor corrections, see Rosemount™ 8800 Vortex Installation Effects Technical Data Sheet.
Steam piping
For steam applications, avoid installations such as the one shown in the following figure. Such installations may cause a water-hammer condition at start-up due to trapped condensation. The high force from the water hammer can stress the sensing mechanism and cause permanent damage to the sensor.
Figure 4-5: Wrong steam pipe installation
Pressure and temperature transmitter location
When using pressure and temperature transmitters in conjunction with the vortex flow meter for compensated mass flows, install the transmitter(s) downstream of the vortex flow meter.

4.1.5 Power supply

The transmitter requires 10 to 30 VDC. The maximum power consumption is
0.4 W.

4.2 Commissioning

For proper configuration and operation, commission the meter before putting it into operation. Bench commissioning also enables you to check hardware settings, test the flowmeter electronics, verify flowmeter configuration data, and check output variables. Any problems can be corrected—or configuration settings changed—before going out into the installation environment. To commission on the bench, connect a configuration device to the signal loop in accordance the device instructions.

4.2.1 Alarm and security jumper configuration

Two jumpers on the transmitter specify the alarm and security modes. Set these jumpers during the commissioning stage to avoid exposing the electronics to the plant environment. The two jumpers can be found on the electronics board stack or on the LCD display.
Alarm
Security
Quick Start Guide 13
The jumper setting for Alarm has no effect when the HART address is set to 1, which is the required setting for the transmitter when configured for use on a Modbus network.
You can protect the configuration data with the security lockout jumper. With the security lockout jumper ON, any configuration
changes attempted on the electronics are disallowed. You can still access and review any of the operating parameters and scroll through the available parameters, but no changes can be made. The factory sets the jumper according to the Configuration Data Sheet, if applicable, or OFF by default.
Note
If you will be changing configuration variables frequently, it may be useful to leave the security lockout jumper in the OFF position to avoid exposing the flow meter electronics to the plant environment.
To access the jumpers, remove the transmitter electronics housing or the LCD cover (if equipped) opposite of the terminal block, See Figure 4-7 and
Figure 4-8.

4.2.2 Calibration

The flow meter is wet-calibrated at the factory and needs no further calibration during installation. The calibration factor (K-factor) is indicated on each meter body and is entered into the electronics. Verification can be accomplished with a configuration device.
