Quick Start Guide
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).

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.
