B. Process temperature °F (°C)
C. 185 °F (85 °C) Housing temperature limit.
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.
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 or
transmitter so heat can be dissipated.
2.1.4 Steam installations
Avoid installation shown in Figure 2-4. Such conditions may cause a water-
hammer condition at start-up due to trapped condensation.
