Installation checklist
□
Make sure that the hazardous area specified on the sensor approval tag is suitable for the environment in which the sensor is installed.
□
Verify that the local ambient and process temperatures are within the limits of the
.
□
If your sensor has an integral transmitter, no wiring is required between the sensor and transmitter. Follow the wiring instructions in the transmitter installation manual for signal and power wiring.
□
If your transmitter has remote-mounted electronics, follow the instructions in this manual for wiring between the sensor and the transmitter, and then follow the instructions in the transmitter installation manual for power and signal wiring.
□
For the wiring between the sensor and the transmitter, consider maximum cable lengths (see
Table 1-1 and Table 1-2 ). The maximum distance between the sensor
and transmitter depends on the cable type. For all types of wiring, Micro Motion recommends using Micro Motion cable.

□
For best performance, follow Micro Motion recommendations for sensor orientation
(see
Table 1-3 ). The sensor will work in any orientation as long as the flow tubes
remain full of process fluid.
Table 1-3: Recommended sensor orientation
Liquids
Gases
Slurries and self-draining applications
□
Install the sensor so that the flow direction arrow on the sensor matches the actual forward flow of the process.
Best practices
The following information can help you get the most from your sensor.
• There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe upstream or downstream are unnecessary.
• If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor. Gases may flow upward or downward.
• Keep the sensor tubes full of process fluid.
• For halting flow through the sensor with a single valve, install the valve downstream from the sensor.
• Minimize bending and torsional stress on the meter. Do not use the meter to align misaligned piping.
• The sensor does not require external supports. The flanges will support the sensor in any orientation.

Notes

•
•
High-temperature sensors:
• Ambient temperature: –40 to +140 °F (–40 to +60 °C)
• Process temperature: –50 to +662 °F (–40 to +350 °C)
When ambient temperature is below –40 °F (–40 °C), a core processor or 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.
Temperature limits may be further restricted by hazardous area approvals. Refer to the hazardous area approvals documentation shipped with the sensor or available from the Micro Motion web site
( www.micromotion.com
).
The extended-electronics option allows the sensor case to be insulated without covering the transmitter, core processor, or junction box, but does not affect temperature ratings.
For F300 sensors, the difference between the process fluid temperature and the average temperature of the case must be less than 120 °F (66 °C).
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.

Mounting
CAUTION!
Do not lift the sensor by the electronics or purge connections. Lifting the sensor by the electronics or purge connections can damage the device.
Attach extended electronics
If you ordered a sensor with extended electronics, you will need to install the extender onto the sensor case.
Note
Extended core processors are matched at the factory to specific sensors. Keep each core processor together with the sensor with which it was shipped.
CAUTION!
Keep the extender and feedthrough clean and dry. Moisture or debris in the extender or feedthrough can damage electronics and result in measurement error or flowmeter failure.
Procedure
1.
Remove and recycle the plastic cap from the feedthrough on the sensor. See

Installation Manual 11
Grounding
4 Grounding
The sensor must be grounded according to the standards that are applicable at the site.
The customer is responsible for knowing and complying with all applicable standards.
Prerequisites
Micro Motion suggests the following guides for grounding practices:
• In Europe, IEC 79-14 is applicable to most installations, in particular Sections
12.2.2.3 and 12.2.2.4.
• In the U.S.A. and Canada, ISA 12.06.01 Part 1 provides examples with associated applications and requirements.
If no external standards are applicable, follow these guidelines to ground the sensor:
• Use copper wire, 14 AWG (2,0 mm 2 ) or larger wire size.
• Keep all ground leads as short as possible, less than 1 Ω impedance.
• Connect ground leads directly to earth, or follow plant standards.
CAUTION!
Ground the flowmeter to earth, or follow ground network requirements for the facility.
Improper grounding can cause measurement error.
Procedure
Check the joints in the pipeline.
If the joints in the pipeline are ground-bonded, the sensor is automatically grounded and no further action is necessary (unless required by local code).
If the joints in the pipeline are not grounded, connect a ground wire to the grounding screw located on the sensor electronics.
Tip
The sensor electronics may be a transmitter, core processor, or junction box. The grounding screw may be internal or external.

Purge the sensor case
If the sensor has purge fittings, they should remain sealed at all times. After a purge plug has been removed, the sensor case should be purged with argon or nitrogen and resealed.
Purging the case protects internal components. The sensor is purged of all oxygen and sealed at the factory. If the purge plugs are never removed, it is not necessary to purge or re-seal the sensor. For more information, contact Micro Motion Customer Service.
If a purge plug is removed from the sensor case, it will be necessary to repurge the case.
CAUTION!
Take all necessary precautions when removing purge plugs. Removing a purge plug compromises the secondary containment of the sensor and could expose the user to process fluid.
CAUTION!
Improper pressurization of the sensor case could result in personal injury. Removing a purge plug will require the sensor case to be repurged with a dry inert gas. Follow all instructions provided in the case purging procedure.
Prerequisites
Make sure the following are available before beginning the purge procedure:
• Teflon ® tape
• Argon or nitrogen gas sufficient to purge the sensor case
Procedure
1.
Shut down the process, or set control devices for manual operation. Before performing the case purging procedure, shut down the process or set the control devices for manual operation. Performing the purge procedure while the flowmeter is operating could affect measurement accuracy, resulting in inaccurate flow signals.
2.
Remove both purge plugs from the sensor case. If purge lines are being used, open the valve in the purge lines.
3.
Prepare the purge plugs for reinstallation by wrapping them with 3–5 turns of Teflon tape.

Supplementary information

4.
Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open.
• Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case.
• If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so that the purge gas will displace air from bottom to top.
• If the purge gas is lighter than air (such as nitrogen), locate the inlet higher than the outlet, so that the purge gas will displace air from top to bottom.
5.
Make sure that there is a tight seal between the inlet connection and sensor case, so that air cannot be drawn by suction into the case or purge line during the purging process.
6.
Run purge gas through the sensor.
The purge time is the amount of time required for full exchange of atmosphere to inert gas. The larger the line size, the greater amount of time is required to purge
. If purge lines are being used, increase the purge time to fill the additional volume of the purge line.
Note
Keep the purge gas pressure below 30 psig (2 bar).

7.
At the appropriate time, shut off the gas supply, then immediately seal the purge outlet and inlet connections with the purge plugs.
Note
Avoid pressurizing the sensor case. If pressure inside the case elevates above atmospheric pressure during operation, the flowmeter density calibration will be inaccurate.
8.
Make sure that the purge fitting seals are tight so that air cannot be drawn by suction into the sensor case.
