Emerson F-SERIES SENSOR Determining a Location, Full flow tubes, Hazardous area installations

Determining a Location

Step 1 Determining a Location

Choose a location for the sensor based on the requirements described in this section. The following general guidelines can help you select an appropriate location for the sensor.

Full flow tubes

For optimal performance, the sensor tubes should remain full of process fluid.

Hazardous area installations

Make sure the hazardous area specified on the sensor approval tag is suitable for the environment in which the sensor is installed (see Figures 1–5). For installation in an area that requires intrinsic safety, refer to the appropriate Micro Motion approval documentation, shipped with the sensor or available from the

Micro Motion web site at www.micromotion.com.

Improper installation in a hazardous area can cause an explosion. When installing in a hazardous area, refer to Micro Motion approvals instructions, shipped with the product or available from the Micro Motion web site. For hazardous installations in Europe, refer to standard EN 60079-14 if national standards do not apply.

Environmental limits

The ambient and process temperature limits of the sensor are shown in Figures 6 and 7:

•For F-Series sensor models other than high-temperature and extreme-high temperature models, see Figure 6.

•For high-temperature and extreme high-temperature F-Series sensors, see Figure 7.
