1.0 About this guide

This guide provides basic guidelines for the Rosemount 8800D Vortex Flowmeter.

It does not provide instructions for detailed configuration, diagnostics,

maintenance, service, troubleshooting, Explosion-proof, Flameproof, or

Intrinsically Safe (I.S.) installations. Refer to the product reference manual for

more instruction. The manuals and this guide are also available electronically on

www.emerson.com/rosemount.

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. Review the approvals section of the

Rosemount 8800D reference manual for any restrictions associated with a safe installation.

Before connecting a handheld communicator in an explosive atmosphere, make sure the instruments in

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

Verify the operating atmosphere of the flowmeter is consistent with the appropriate product

certifications.

In an Explosion-proof/Flameproof installation, do not remove the flowmeter covers when power is applied

to the unit.

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.

2.0 Installation

2.1 Mount the flowmeter

Design process piping so the meter body will remain full, with no entrapped air.

The vortex flowmeter can be installed in any orientation without affecting

accuracy. However, the following are guidelines for certain installations.

Vertical mounting

If the vortex flowmeter will be installed in a vertical orientation:

Install upward or downward flow for gas or steam.

Install upward flow for liquids.

Figure 1. Vertical Installation

Horizontal mounting

Figure 2. Horizontal Installation

For steam and fluids with small solids content, it is recommended to have the

flowmeter installed with the electronics to the side of the pipe. This will minimize

potential measurement errors by allowing the condensate or solids to flow under

the shedder bar without interrupting the vortex shedding.

High temperature mounting

The maximum temperature for integral electronics is dependent on the ambient

temperature where the flowmeter is installed. The electronics must not exceed

185 °F (85 °C).

Figure 3 shows combinations of ambient and process temperatures needed to

maintain a housing temperature of less than 185 °F (85 °C).

Figure 3. Rosemount 8800D Ambient/Process Temperature Limits(1)

The following orientations are recommended for applications with high process

temperatures.

Install with electronics head beside or below process pipe.

Insulation around pipe may be necessary to maintain ambient temperature

below 185 °F (85 °C).

Note

Insulate pipe and meter body only. Do not insulate support tube bracket so heat can be dissipated.

1. The indicated limits are for horizontal pipe and vertical meter position, with meter and pipe insulated with three

inches of ceramic fiber.

Steam installations

Avoid installation shown in Figure 4. Such conditions may cause a water-hammer

condition at start-up due to trapped condensation.

Figure 4. Improper Installation

Upstream/downstream requirements

The Rosemount 8800D Flowmeter may be installed with a minimum of 10

straight pipe diameters (10D) upstream and five straight pipe diameters (5D)

downstream by following the K-factor corrections as described in the Rosemount

8800 Installation Effects Technical Data Sheet. No K-factor correction is required

if 35 straight pipe diameters upstream (35D) and five straight pipe diameters

downstream (5D) are available.

External pressure/temperature transmitters

When using pressure and temperature transmitters in conjunction with the

8800D for compensated mass flows, install the transmitters downstream of the

Rosemount 8800D Flowmeter as shown in Figure 5.

B. Gaskets (supplied by customer)

Note

The required bolt load for sealing the gasket joint is affected by several factors, including

operating pressure, gasket material, thickness, and condition. A number of factors also affect the

actual bolt load resulting from a measured torque, including condition of bolt threads, friction

between the nut head and the flange, and parallelism of the flanges. Due to these

application-dependent factors, the required torque for each application may be different. Follow

the guidelines outlined in the ASME PCC-1 for proper bolt tightening. Make sure the flowmeter is

centered between flanges of the same nominal size as the flowmeter.

Installation procedures

Note

Step number of procedure corresponds with number in drawing (Figure 1).

1. Slide the thermocouple bolt (1) over the thermocouple (TC).

2. Place the 2-part ferrule (2) over the end tip of the thermocouple (TC).

3. Insert the thermocouple in to the thermowell hole (TW) on the bottom side of

the meter body.

a. Important! Carefully push the thermocouple in to the thermowell

completely. This is critical to get the proper insertion depth. Then thread

the thermocouple bolt in to the hole.

b. When the thermocouple bolt is hand tight, mark the position of the bolt in

relation to the meter body (the mark will help determine rotations). Using a

½-in. wrench turn the bolt clockwise ¾turn to seat the ferrule.

Note

After completing the above step, the ferrule and thermocouple bolt will be permanently installed

on the thermocouple.

4. Verify the rubber O-ring is installed on the electronics connection end of the

thermocouple.

5. Verify the 2.5 mm hex head screw is installed.

6. Insert the electronics end connector in to the transmitter housing. Tighten

the screw with a 2.5 mm hex bit to secure the connection.

Important! Do not over tighten hex screw.

Remote electronics

If you order one of the remote electronics options (options R10, R20, R30, R33,

R50, or RXX), the flowmeter assembly ships in two parts:

The meter body with an adapter installed in the support tube and an

interconnecting coaxial cable attached to it.

The electronics housing installed on a mounting bracket.

If you order the armored remote electronics options, follow the same instructions

as for the standard remote cable connection with the exception that the cable

may not need to be run through conduit. Armored includes the glands.

Mounting

Mount the meter body in the process flow line as described earlier in this section.

Mount the bracket and electronics housing in the desired location. The housing

can be repositioned on the bracket to facilitate field wiring and conduit routing.

Cable connections

Refer to Figure 9 and the instructions on page 9 to connect the loose end of the

coaxial cable to the electronics housing.

Note

Consult factory for SST installation.

1. If the coaxial cable will be run in conduit, carefully cut the conduit to the

desired length to provide for proper assembly at the housing. A junction box

may be placed in the conduit run to provide a space for extra coaxial cable

length.

Caution

The coaxial remote cable cannot be field terminated or cut to length. Coil any extra coaxial cable

with no less than a 2-in. (51 mm) radius.

2. Slide the conduit adapter or cable gland (A) over the loose end of the coaxial

cable (B) and fasten it to the adapter (C) on the meter body support tube (H).

3. If using conduit, rout the coaxial cable through the conduit.

4. Place a conduit adapter or cable gland (L) over the end of the coaxial cable.

5. Remove the housing adapter (N) from the electronics housing (J).

6. Slide the housing adapter (N) over the coaxial cable.

7. Remove one of the four housing base screws (O).

8. Attach and tighten the coaxial cable nut (K) to the connection on the

electronics housing.

9. Attach the coaxial cable ground wire (P) to the housing (J) via the housing

base ground screw (O).

10. Align the housing adapter (N) with the housing (J) and attach with the

provided screws (M).

11. Tighten the conduit adapter or cable gland (L) to the housing adapter (N).

Caution

To prevent moisture from entering the coaxial cable connections, install the interconnecting

coaxial cable in a single dedicated conduit run or use sealed cable glands at both ends of the cable.

Note

Refer to the reference manual for details for the CPA option.

2.2 Consider housing rotation

The entire electronics housing may be rotated in 90° increments for easy viewing.

Use the following steps to change the housing orientation:

1. Loosen the three housing rotation set screws at the base of the electronics

housing with a 5/32-in. hex wrench by turning the screws clockwise (inward)

until they clear the support tube.

2. Slowly pull the electronics housing out of the support tube.

April 2016

Quick Start Guide

Caution

Do not pull the housing more than 1.5-in. (40 mm) from the top of the support tube until the

sensor cable is disconnected. Damage to the sensor may occur if this sensor cable is stressed.

3. Unscrew the sensor cable from the housing with a 5/16-in. open end wrench.

4. Rotate the housing to the desired orientation.

5. Hold in this orientation while screwing sensor cable onto base of the housing.

Caution

Do not rotate the housing while the sensor cable is attached to the base of the housing. This will

stress the cable and may damage the sensor.

6. Place the electronics housing into the top of the support tube.

7. Use a 5/32-in. hex wrench to turn the three housing rotation screws

counter-clockwise (outward) to engage the support tube.

2.3 Set jumpers

Adjust jumpers to desired settings.
