Determining a Location
Figure 4 High-temperature or extreme high-temperature ELITE sensor
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 1–4.) 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 5 and 6:
• For ELITE sensor models other than high-temperature and extreme-high temperature models, see
Figure 5.
• For high-temperature and extreme high-temperature ELITE sensors, see Figure 6.
