1.1 Installation checklist

□ Make sure that the hazardous area specified on the approval tag is suitable for the

environment in which the meter will be installed.

□ Verify that the local ambient and process temperatures are within the limits of the

meter.

□ 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.

Installation Manual

□ Install the meter so that the flow direction arrow on the sensor case matches the actual

forward flow of the process. (Flow direction is also software-selectable.)

1.2 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 should flow 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.

1.3 Temperature limits

Sensors can be used in the process and ambient temperature ranges shown in the
temperature limit graphs. For the purposes of selecting electronics options, temperature
limit graphs should be used only as a general guide. If your process conditions are close to
the gray area, consult with your Micro Motion representative.

Note

• In all cases, the electronics cannot be operated where the ambient temperature is

below -40 °F (-40.0 °C) or above 140 °F (60.0 °C). If a sensor is to be used where the
ambient temperature is outside of the range permissible for the electronics, the
electronics must be remotely located where the ambient temperature is within the
permissible range, as indicated by the shaded areas of the temperature limit graphs.

• 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.emerson.com/flowmeasurement).

• The extended-mount electronics option allows the sensor case to be insulated without

covering the transmitter, core processor, or junction box, but does not affect
temperature ratings. When insulating the sensor case at elevated process
temperatures (above 140 °F (60.0 °C)), please ensure electronics are not enclosed in
insulation as this may lead to electronics failure.

Grounding

4 Grounding

The meter 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

Use 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 (2.08 mm²) 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.

5.1 Purge the sensor case

Prerequisites

Make sure the following are available before beginning the purge procedure:

• Teflon™ tape

• Argon or nitrogen gas sufficient to purge the sensor case

About this task

Whenever a purge plug is removed from the sensor case, you must repurge the 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.

DANGER

• Stay clear of the rupture disk pressure relief area. High-pressure fluid

escaping from the sensor can cause severe injury or death. The sensor must
be oriented so that personnel and equipment will not be exposed to any
discharge along the pressure relief path.

• 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.

• Improper pressurization of the sensor case could result in personal injury.

CAUTION
Be sure to use thread protectors when removing the purge fitting so as not to
damage the disk membrane surrounding the rupture disk.

3. Prepare the purge plugs for reinstallation by wrapping them with 2–3 turns of
Teflon tape.

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.

Installation Manual 23

Supplementary information Installation Manual

January 2019 20002298

• 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
the case. 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 7.25 psi (0.5 bar).

Table 5-1: Purge time

Sensor model Purge rate Time, in minutes

F025 20 ft3/h (566.3 l/h) 4 1/2

F050 20 ft3/h (566.3 l/h) 4 1/2

F100 20 ft3/h (566.3 l/h) 6

F200 20 ft3/h (566.3 l/h) 15

F300 20 ft3/h (566.3 l/h) 25

7. At the appropriate time, shut off the gas supply, then immediately seal the purge
outlet and inlet connections with the purge plugs.

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.

5.2 Pressure relief

F-Series sensors, except high-temperature (base model codes A and B), are available with a
rupture disk installed on the case. Rupture disks are meant to vent process fluid from the
sensor case in the unlikely event of a flow tube breach. Some users connect a pipeline to
the rupture disk to help contain escaping process fluid. For more information about
rupture disks, contact Micro Motion Customer Service.

If the sensor has a rupture disk, it should remain installed at all times as it would otherwise
be necessary to re-purge the case. If the rupture disk is activated by a tube breach, the seal
in the rupture disk will be broken, and the Coriolis meter should be removed from service.

The rupture disk is located as follows on the meter, and the warning sticker shown is
placed next to it.

24 Micro Motion F-Series

Installation Manual Supplementary information

20002298 January 2019

DANGER
Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from
the sensor can cause severe injury or death.

The sensor must be oriented so that personnel and equipment will not be exposed to any
discharge along the pressure relief path.

Important

If a rupture disk is used, the housing can no longer assume a secondary containment
function.

WARNING
Removing the Purge Fitting, Blind Plug, or Rupture Disks compromises the Ex-i Safety
Certification, the Ex-tc Safety Certification, and the IP-rating of the Coriolis meter.
Any modification to the Purge Fitting, Blind Plug, or Rupture Disks must maintain a
minimum of IP66/IP67 Ratings.
