Important Information
!!!
Read these instructions carefully and look at the equipment to become familiar with the device
before trying to install, operate, service, or maintain it. The following special messages may
appear throughout this manual or on the equipment to warn of potential hazards or to call
attention to information that clarifies or simplifies a procedure.
The addition of either symbol to a “Danger” or “Warning” safety label
indicates that an electrical hazard exists which will result in personal injury
if the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential personal injury
hazards. Obey all safety messages that follow this symbol to avoid possible injury or
death.
DANGER
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WAR NIN G indicates a hazardous situation which, if not avoided, could result in death or
serious injury.
CAUTION indicates a hazardous situation which, if not avoided, could result in minor or
moderate injury.
NOTICE is used to address practices not related to physical injury.
Please Note
Electrical equipment should be installed, operated, and maintained only by qualified personnel.
No responsibility is assumed by Schneider Electric for any consequences arising out of the use of
this material.
A qualified person is one who has skills and knowledge related to the construction, installation,
and operation of electrical equipment and has received safety training to recognize and avoid the
hazards involved.

1. Introduction
Overview
The CFT51 Digital Coriolis Mass Flow Transmitter, when used with a Foxboro® CFS flowtube,
measures the mass flow rate, density, and temperature of process fluid directly. It uses digital signal
processing technology in conjunction with the Coriolis principle. The transmitter provides
frequency, scaled pulse, 4 to 20 mA current, alarm, and contact outputs. It also supports
nonvolatile totalization of the output.
You can configure the CFT51 transmitter to use the HART or Modbus communication protocol
via LCD indicator pushbuttons on the transmitter at any time.
HART communications protocol can be used in full digital communications mode to a HART
host system, or as a direct analog communications interface over the 4-20 mA analog signal with a
HART communicator or the configuration software.
Modbus communications protocol allows full digital communications using a Modbus
communication interface.
Local communication is always available using the LCD indicator/configurator.

Electrical Safety Warnings
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Do not open while circuits are live.
Do not open when energized or when an explosive atmosphere may be present.
Substitution of components may impair intrinsic safety or Division 2 approvals.
Failure to follow these instructions can result in death or serious injury.
For Explosionproof Certifications
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Keep cover tight while circuits are live unless area is known to be nonhazardous.
To help prevent ignition of flammable or combustible atmospheres, disconnect power before
servicing.
The flowtube junction boxes contain more than 10% aluminum and are considered to
constitute a potential risk of ignition by impact or friction. Care must be taken to prevent
impact and friction when installing or using the junction box in a Zone 0 installation.
Failure to follow these instructions can result in death or serious injury.
CAUTION
EQUIPMENT OPERATION HAZARD
The CFT51 transmitter is to be used only with a Foxboro CFS flowtube in accordance with
control drawings MI 019-141 and MI 019-179.
Failure to follow these instructions will result in injury or equipment damage.

2. Installation
Mounting
Four 0.437-20 UNS threaded holes are provided on the surface of the enclosure on which a
carbon steel mounting bracket or optional stainless steel (SS) mounting bracket can be attached.
The other surface of the bracket allows for mounting to a surface, or to a nominal DN50 (2 inch)
vertical or horizontal pipe. An optional bracket is available for mounting to a DN80 (3 inch)
vertical or horizontal pipe. See Figure 2.

MI 019-140 – November 2019 2. Installation
Positioning the Housing
The housing can be positioned at almost any angle in a horizontal plane by loosening the bracket
bolt and turning the housing with respect to the mounting bracket. See Figure 2.
The CFT51 transmitter can be mounted to a wall as displayed in Figure 3.
Figure 3. Wall Mounting
The transmitter can be mounted horizontally or vertically to a pipe. Some of the more common
mounting configurations are shown in Figures 4, 5, 6 and 7.

Rotating the Display
The Display/Configurator can be rotated in 90 degree increments in the display bezel. The
display bezel does not rotate, and must always be mounted in the housing in the orientation
shown in Figure 8.
Figure 8. Display Orientation
To rotate the display to the desired orientation:
1. Remove the display assembly by loosening the captive screws.
2. Remove the short screw that retains the ferrite bead bracket and the dampener foam to
the back of the molding. Be careful to retain the screw for reassembly.
3. Remove the Local Display/Configurator from the Display Bezel by removing the long
screws that retain the assembly to the front of the molding.
4. Rotate the Local Display/Configurator to the desired orientation with the display
assembly molding and feed the cable of the Local Display/Configurator through the
corresponding opening in the molding.
5. Attach the Local Display/Configurator to the bezel using the long screws.
6. Place the dampener foam and the bracket over the ferrite bead on the cable and attach
the Local Display/Configurator to the Display Bezel using the short screw.
7. Place the reassembled display assembly in line with the required orientation as shown.
8. Attach the assembly to the housing using the captive screws.
The display bezel is not rotatable. The bezel must always be aligned with the housing
as shown in Figure 8 to retain the jumper configurations on the electronic module.

NOTE
Cover Lock Versions
Various lock and seal mechanisms are available with the CFT51. One or more of these locking
mechanisms may be required for specific applications.
For all model code selections, locking pins are provided for the round electronic
housing covers (Figure 9). These cover locking mechanisms are required for all agency
flameproof applications.
For the Tamperproof Sealing (-S), U.S. Weights and Measures Custody Transfer
NTEP (-T), and Weights and Measures Industry Canada Approvals (-D) model code
selections:
Locking pins are provided with an additional seal wire and crimp seal for the
round electronic housing covers (Figure 10).
Additional locking mechanisms are provided for the transmitter junction box
(Figure 17) and flowtube junction box (CFS10 and CFS20 flowtubes only,
Figure 18).
The U.S. Weights and Measures Custody Transfer NTEP (-T) and Weights and
Measures Industry Canada Approvals (-D) model code selections are applicable only
when the transmitter is used with CFS10 or CFS20 flowtubes.

LOCKING PINS
Locking Pins
To lock the two round transmitter housing covers, unscrew each locking pin (provided with all
model code selections) until approximately 6 mm (0.25 in) engages the groove on the cover. Note
that the two round transmitter housing covers must be locked for all agency (ATEX, CSA, FM,
IECEx) flameproof certifications.
