IMPORTANT NOTICE
This installation guide provides basic guidelines for the Rosemount® Model 8800C Vortex
Flowmeter. It does not provide instructions for detailed configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-Proof, Flame-Proof, or Intrinsically
Safe (I.S.) installations. Refer to the Model 8800C reference manual (document number
00809-0100-4003) and Model 8800C Foundation fieldbus manual (document number
00809-0100-4772) for more instruction. The manuals and this QIG are also available
electronically on www.rosemount.com.
WAR N ING
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 Model 8800C reference manual for any restrictions
associated with a safe installation.
• Before connecting a HART-based 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/Flame-Proof 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.

STEP 1: MOUNT THE TRANSMITTER
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
Gas Flow
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 2 shows combinations of ambient and process temperatures needed to maintain a
housing temperature of less than 185°F (85°C).

The following orientations are recommended for applications with high process
temperatures.
• Install with meter body 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.

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.

Steam Installations
Avoid installation shown Figure 4. Such conditions may cause a water-hammer condition at
startup due to trapped condensation.

8800g15c
Upstream/Downstream Requirements
The Model 8800C Flowmeter may be installed with a minimum of ten straight pipe diameters
(D) upstream and five straight pipe diameters (D) downstream by following the K-factor
corrections as described in the Model 8800C Installation Effects Technical Data Sheet
(00816-0100-3250). No K-factor correction is required if 35 straight pipe diameters upstream
(35D) and 10 straight pipe diameters downstream (10D) are available.
When using pressure and temperature transmitters in conjunction with the Model 8800C for
compensated mass flows install the transmitters downstream of the Model 8800C flowmeter
as shown in Figure 5.

The required bolt load for sealing the gasket joint is affected by several factors, including
operating pressure and gasket material, width, 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 Pressure Vessel Code (Section VIII,
Division 2) for proper bolt tightening. Make sure the flowmeter is centered between flanges
of the same nominal size as the flowmeter.

Remote Electronics
If you order one of the remote electronics options (options R10, R20, R30, or RXX), the
flowmeter assembly ships in two parts:
1. The meter body with an adapter installed in the support tube and an interconnecting
coaxial cable attached to it.
2. The electronics housing installed on a mounting bracket.
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 8 and the instructions on page 7 to connect the loose end of the coaxial
cable to the electronics housing.
