4 Pre-installation

4.1 Planning

For a successful installation, consider each aspect of your application and the meter you are installing.

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.
For sizing details, refer to the product reference manual.
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 B
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 do not strike the shedder bar and disrupt 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. See Product
certifications.
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.
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
Quick Start Guide 11
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.

HART communication
Figure 4-7: HART communication voltage/resistance requirement
Maximum loop resistance is determined by the voltage level of the external power supply, as described in the graph.
Note that HART Communication requires a minimum loop resistance of 250 ohms up to a maximum of 1100 ohms.

Minimum power supply voltage required
R(Ω)max = 41.7 (Vps – 10.8 V).
Additional wiring information
• The DC power supply should provide power with less than two percent
ripple. The total resistance load is the sum of the resistance of the signal wiring and the load resistance of the controller, indicator, and related pieces. Note that the resistance of intrinsic safety barriers, if used, must be included.
• If a Smart Wireless THUM™ Adapter is being used with the flow meter to
exchange information via IEC 62591 (WirelessHART® Protocol) technology, a minimum loop resistance of 250 ohms is required. In addition, a minimum power supply voltage (Vps) of 19.3 volts will be required to output 24 mA.
• If a single power supply is used to power more than one transmitter, the
power supply used and circuitry common to the transmitters should not have more than 20 ohms of impedance at 1200 Hz. See Table 4-1.

4.1.6 Power supply (FOUNDATION fieldbus)

The flowmeter requires 9-32 Vdc at the power terminals. Each fieldbus power supply requires a power conditioner to decouple the power supply output from the fieldbus wiring segment.

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.
(20 °C) equivalent

4.2.1 HART 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 meter.
Alarm
Security
Quick Start Guide 15
As part of normal operations, the transmitter continuously runs a self-diagnostic routine. If the routine detects an internal failure in the electronics, flow meter output is driven to a low or high alarm level, depending on the position of the failure mode jumper. The factory sets the jumper according to the Configuration Data Sheet, if applicable, or HI by default.
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 blocks, See Figure 4-8 and
Figure 4-9.
