Figure 3. Rosemount 8800D Ambient/Process Temperature Limits
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.
Steam Installations
Avoid installation shown 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 ten straight pipe
diameters (D) upstream and five straight pipe diameters (D) downstream by following the
K-factor corrections as described in the 8800 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.
