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.

Determining a Location
Maximum wiring distances
If the transmitter is mounted remotely from the sensor, the maximum distance between the sensor and
transmitter depends on cable type. See Table 2.
For high-temperature and extreme high-temperature ELITE sensors, note the following:
• For sensors with a Model 1700/2700 or a Model 2400S transmitter, the transmitter is considered to be
integrally mounted on the sensor, so Table 2 does not apply.
• For sensors with a junction box or core processor, the limits in Table 2 apply only to the wiring
between the junction box or core processor and a remotely-mounted transmitter. The length of the
flexible conduit on which the junction box or core processor is mounted does not need to be
considered.
Pipe run
Micro Motion sensors do not require a straight run of pipe upstream or downstream.
Valves
Meter zero can be adjusted for special circumstances. When zeroing is performed with the auto-zero feature of
the transmitter, it is necessary to halt flow through the sensor, with the sensor tubes full of process fluid at
typical process conditions. The valve used to halt flow in this situation should be downstream from the sensor.
It is also possible to restore the meter’s factory zero setting. For more information about zeroing, refer to the
instruction manual shipped with the transmitter.

Orienting the Sensor
Step 2 Orienting the Sensor
The sensor will function properly in any orientation if the sensor tubes remain filled with process fluid.
Micro Motion recommends orienting ELITE sensors as shown in Table 3.
Flow direction arrow
The sensor has a flow direction arrow (see Figures 1–4) to help you configure the transmitter for flow
direction. If possible, install the sensor so that the flow direction arrow matches actual process flow.
Vertical pipeline
If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor.
Gases may flow upward or downward.

Mounting the Sensor
Step 3 Mounting the Sensor
Use your common practices to minimize torque and bending load on process connections. Figure 7 illustrates
how to mount the sensor. To reduce the risk of condensation or excessive moisture, the conduit opening
should not point upward (if possible). The conduit opening of the junction box or core processor can be
rotated freely to facilitate wiring.
The CMF010 sensor has an optional mounting configuration (Figure 8) for use with small or soft pipeline.
Figure 7 Mounting an ELITE sensor
Figure 8 Optional mounting for CMF010 sensors
If the pipeline will not support
the sensor, mount the sensor
using bolts as illustrated.
2 × user supplied bolts
•5/16″(M8) maximum diameter
•21/4″(58 mm) minimum length
Junction box or core processor (junction box
shown)
• Junction box can be rotated by hand
(before wiring is attached) for access to
mounting holes
• Core processor does not need to be
rotated for access to mounting holes
If necessary, rigid standoffs (e.g., steel washers)
can be installed
Mounting surface — if pipe supports are used, they
should be rigidly supported by the same mounting
surface that supports the sensor

Mounting the Sensor
Installing extended mount electronics
If you ordered a sensor with an extended mount for the electronics, you will need to install the extender. To
install the extended mount electronics:
1. There is a metal clamping ring around the base of the feedthrough (Figure 9). Remove this ring and set
it aside. You will use it later to secure the extender to the sensor.
2. The sensor was shipped with a plastic cap over the feedthrough pins. Remove the plastic cap and
discard it.
3. There is a plastic plug inside the extended mount (Figure 10). Remove the plug and discard it.
4. Place the extended mount onto the feedthrough and carefully rotate the extender until the feedthrough
notches line up. Being careful not to damage the feedthrough pins, push the extender down onto the
feedthrough until it is fully engaged.
5. Replace the clamping ring on the feedthrough. Tighten the ring’s screw to 13–18 in-lbs (1.5–2 N-m).

Installing wafer-style sensors
A wafer-style sensor, which has no flanges or fittings, lets you “clamp” the sensor between process
connections in the pipeline. Model CMF025, CMF050, and CMF100 sensors are available in the wafer style.
A wafer installation kit is shipped with a wafer-style sensor. A wafer kit contains the following pieces:
• 4 flange bolts
• 8 flange nuts
• 2 alignment rings, which help center the sensor between the bolts
To install a wafer-type sensor, refer to Figures 12 and 13 and follow the steps below:
1. Make sure the bolts provided in the wafer installation kit are rated for your process connection.
2. Slip the sensor alignment rings over each end of the sensor wafer, then insert the sensor between the
process connections in the pipeline (Figure 12). Installing gaskets is recommended. (Micro Motion
does not supply gaskets.)
3. Insert the bolts through both process connections, and thread the nuts onto the bolts. Tighten nuts as
tight as you can with your fingers.
4. Rotate the sensor alignment rings in the direction that pushes the bolts outward (Figure 13). Rotate
both rings until the assembly is centered and tight.
5. With a wrench, tighten nuts in an alternating order, to ensure the process connections are evenly
tightened.

Wiring
Step 4 Wiring
Hazardous area installations
If you are installing the sensor in a hazardous location, verify that the hazardous classification information
printed on the sensor tag matches the environment in which the sensor will be installed.
Improperly sealed housings can expose electronics to moisture, which can cause measurement error
or flowmeter failure. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing
covers and conduit openings.
Installation options
The sensor has one of the following configurations:
• An integral Model 2400S (all models) or Model 1700/2700 transmitter (high-temperature and extreme
high-temperature models only). No wiring is required between the sensor and the transmitter. Skip to
Grounding on page 20.
• A core processor to a 4-wire remote transmitter (requires 4-wire cable); see Core processor to a 4-wire
remote transmitter on page 16.
• A core processor to a remote host (requires 4-wire cable); refer to the Micro Motion MVD™Direct
Connect™Meters Installation Manual.
• A junction box to a 9-wire remote transmitter or remote core processor (requires 9-wire cable); see
Junction box to a 9-wire remote transmitter or remote core processor on page 19.
Core processor to a 4-wire remote transmitter
Follow the steps below to connect the 4-wire cable between the core processor and the transmitter.
1. Use one of the following methods to shield the wiring from the core processor to the transmitter:
• If you are installing unshielded wiring in continuous metallic conduit that provides 360°
termination shielding for the enclosed wiring, go to page 18 (step 6 of the wiring procedure).
• If you are installing a user-supplied cable gland with shielded cable or armored cable, terminate
the shields in the cable gland. Terminate both the armored braid and the shield drain wires in the
cable gland. Never connect the drain wires to the internal ground screw of the core processor. Go
to page 18 (step 6 of the wiring procedure).
• If you are installing a Micro Motion-supplied cable gland at the core processor housing:
- Prepare the cable and apply shielded heat shrink as described below. The shielded heat shrink
provides a shield termination suitable for use in the gland when using cable whose shield
consists of foil and not a braid. Proceed to step 2 of the wiring procedure, below.
- With armored cable, where the shield consists of braid, prepare the cable as described below,
but do not apply heat shrink. Proceed to step 2 of the wiring procedure, below.
2. Remove the cover from the core processor housing.
3. Slide the gland nut and the clamping insert over the cable.

Installation Manual 17
Wiring
Figure 14 Micro Motion cable gland and heat shrink
4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable,
omit steps d, e, f, and g):
a. Strip 4 1/2 inches (114 mm) of cable jacket.
b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the
wires.
c. Remove the foil shield that is around the insulated wires, leaving 3/4 inch (19 mm) of foil or braid
and drain wires exposed, and separate the wires.
d. Wrap the shield drain wire(s) around the exposed foil twice. Cut off the excess wire.
Figure 15 Wrapping the shield drain wires
e. Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely
cover the drain wires.
f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing.

i. Install the gland body into the core processor housing conduit opening.
Figure 18 Gland body and core processor housing
5. Insert the wires through the gland body and assemble the gland by tightening the gland nut. If desired,
leave sufficient wire length inside the core processor housing to allow the housing to rotate without
damaging the wires.
6. Identify the wires in the 4-wire cable. The 4-wire cable supplied by Micro Motion consists of one pair
of 18 AWG (0,80 mm2) wires (red and black), which should be used for the VDC connection, and one
pair of 22 AWG (0,35 mm2) wire (green and white), which should be used for the RS-485 connection.
Connect the four wires to the numbered slots on the core processor (Figure 19).
