This Micro Motion product complies with all applicable European directives when properly installed in
accordance with the instructions in this manual. Refer to the EC declaration of conformity for directives that
apply to this product.
The EC declaration of conformity, with all applicable European directives, and the complete ATEX
Installation Drawings and Instructions are available on the internet at www.micromotion.com/atex or
through your local Micro Motion support center.
Information affixed to equipment that complies with the Pressure Equipment Directive can be found on the
internet at www.micromotion.com/documentation.
Installation options
The ELITE sensor makes up one part of a Coriolis flowmeter. The other part is a transmitter. ELITE sensors
are available with the following electronics interfaces:
• An integral Model 2400S transmitter or enhanced core processor (see Figure 1).
• An integral core processor for connecting to a 4-wire remotely mounted transmitter or to a
user-supplied remote host (see Figure 2).
• A 9-wire junction box for connecting to a remotely mounted transmitter or a remotely mounted core
processor (see Figure 3).
• High-temperature and extreme high-temperature models are equipped with a flexible conduit, on
which can be mounted a Model 2400S transmitter, a Model 1700/2700 transmitter, a core processor, or
a junction box (see Figure 4).

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.

Notes:
1. When ambient temperature is below –40 °F (–40 °C), a core processor or Model 2400S transmitter must be heated to bring
its local ambient temperature to between –40 °F (–40 °C) and +140 °F (+60 °C). Long-term storage of electronics at
ambient temperatures below –40 °F (–40 °C) is not recommended.
2. Temperature limits may be further restricted by hazardous area approvals.
3. The extended mount option allows the sensor case to be insulated without covering the transmitter, core processor, or
junction box, but does not affect temperature ratings.
4. For the purposes of selecting electronics options, this graph should be used only as a general guide. If your process
conditions are close to the gray areas, it may be inappropriate to use electronics options other than a junction box. Consult
with your Micro Motion representative.

Hazardous area approvals may impose additional limits on ambient and process temperature. For the ATEX
“T” rating, refer to the ATEX documentation shipped with the sensor or available on the Micro Motion web
site at www.micromotion.com. IECEx and NEPSI approvals also use the ATEX “T” rating. UL and CSA
ambient temperature limits are listed in Table 1.
