STEP 1. Choosing a location
Choose a location for the sensor based on the requirements described in
this section.
General guidelines
The following conditions must be met:
• Before operation, you must be able to stop flow through the sensor.
(During the zeroing procedure, flow must be stopped completely, and
the sensor must be full of process fluid.)
• During operation, the sensor must remain full of process fluid.
• The sensor must be installed in an area that is compatible with the
classification specified on the sensor approvals tag (see Figure 1 and
Figure 4).
Hazardous area installations
Make sure the hazardous areas specified on the approvals tags are suitable
for the environment in which the sensor and booster amplifier will be
installed. See Figures 1 and 4. For installation in an area that requires
intrinsic safety, refer to Micro Motion UL, CSA, or ATEX
documentation, shipped with the sensor or available from the Micro
Motion web site.
For a complete list of hazardous area classifications for Micro Motion
sensors, refer to the EXPERT
