Installation and Operation Guide
Pre-Installation
The ST51 can be specied with integral or remote electronics. The ow element has a serial number etched into the side of the
extension pipe as shown in Figure A. The transmitter circuit card has a serial number noted on the board as shown in Figure B. The
ow sensor and transmitter circuit have been calibrated as a matched set and should be paired together in service unless otherwise
approved by a factory technician.
Flow Direction Alignment
All sensor elements have a ow arrow indicator marked on the element assembly at the reference at. These ow elements have
been calibrated in a particular direction and are designed to be used in service with the ow arrow facing in the same direction as
ow in the pipe stream. See Appendix C for orientation and factory calibration details.
Recommended Straight Run
To optimize ow meter system performance, FCI recommends installation with a minimum of 20 pipe diameters upstream
straight run and 10 pipe diameters of downstream straight run. Where straight run limitations signicantly reduce the available
pipe diameters, FCI uses Vortab ow conditioners to produce a transferable ow prole from the calibration installation to actual
eld installations. FCI’s proprietary AVAL software is available to make ow meter installation evaluations where straight run
limitations are considered. See Figure C for recommended installation.
Figure C
FCI ow meters may be installed with less than the recommended straight run, but may have performance limitations. FCI offers
Vortab ow conditioners for use in applications that have signicant straight run limitations. FCI uses the AVAL application
modeling software to predict meter performance in each installation. AVAL outputs are available to review prior to order
placement and will indicate performance expectations both with and without V
ortab ow conditioning.

Installing Flow Element
Compression Fitting Mounting
Caution: The element is shipped with a protective sleeve surrounding the ow element. After removing the sleeve, take
care to prevent the element from sliding through the compression tting and contacting the opposing wall with any force
as it may cause damage to the element and potentially upset the calibration.
The ST51 is available with both

for continuous adjustments. The metal ferrule version can only be tightened down once and it becomes permanently positioned.
The ferrule type is indicated in the instrument part number displayed on the instrument tag. This can be cross referenced to the
ordering information sheet.
All ow meters have been calibrated with the ow element located at the centerline of the pipe and ow stream as indicated in
Figure D. Couplings and threadolets come in various dimensions. Proper installation requires that the element be measured with
consideration to process connection dimensions and pipe centerline. FCI recommends that the element be rst installed in the line
with the compression tting lightly tightened around the extension, then slowly move the pipe extension forward until the element
is at centerline as shown.
Caution: On top mount installations, particularly, take care to prevent the element from sliding through the compression
tting and contacting the opposing wall with any force as it may cause damage to the element and potentially upset the
calibration.

To assist in nal installation, FCI suggests making a readable mark on the extension pipe to indicate the nal desired compression
tting position that will place the element at the centerline reference once the system is tightened down into place. With the
compression tting lightly tightened, hold the element assembly along the outside of the installation, or directly above, to visually
check the compression tting’s centerline installation. To calculate the actual “U” length dimension, take the inside diameter
of the pipe or duct divide by 2, then add 0.25″, then add for the pipe wall thickness and the process tting offset that allows the
compression tting to securely seat in the process port. See Figure D above.
Align the at parallel to ow and adjust the instrument depth. Upon determination of the nal compression tting location on
the extension pipe, apply the proper thread sealant to the NPT threads and rmly tighten the compression tting into the mating
process connection. Torque varies per application. Tighten the compression nut to the torque indicated with the corresponding
ferrule material. Manufacturer recommends 1-1/4 turns from hand-tight baseline.

Retractable Packing Gland Mounting
A retractable packing gland, with ½″ MNPT
or ¾″ MNPT threads and graphite or Teon packing, is a process connection option.
FCI single point ow meters are calibrated at the centerline of the process pipe. The ow element is properly mounted when the
tip of the ow element is located .50 inches (13 mm) past the pipe centerline. Follow the below steps to install/retract instruments
with the retractable packing gland option.
1. The scale etched on the side of the insertion probe indicates the length to the tip of the ow element. Calculate the insertion
depth using the equation, variables, and Figure E below.
ID = Inside Diameter of Pipe
T = Pipe Wall Thickness
C = Mounting Coupling with Optional Ball Valve and Installed Packing Gland Length
INSERTION DEPTH = ______________
Figure E
2. Mark the insertion pipe at the calculated insertion depth.
3. Ball Valve Applications Only: If a ball valve is required, install the ball valve to the process mounting coupling. Close the
ball valve to prevent the process media from leaking out when installing the packing gland with the process line pressurized.
4. Apply the proper thread sealant compatible with the process media to the male threads of the packing gland. Fully retract the
insertion probe into the cavity of the packing gland and install the packing gland into the process mounting coupling or ball
valve. If a ball valve is not used, make sure to rst depressurize the process line before installing.

Page 5
ST51 Mass Flow Meter Fluid Components International LLC
5. Tighten the packing nut until the internal packing is tight enough to prevent excess process leakage, but also allow the
insertion probe to be inserted into place. For ball valve applications, open the ball valve after the packing nut has been
tightened.
Caution: For applications where the process media is pressurized to greater than 232 psig [16 bar(g)] make sure to rst
depressurize the process line before making the insertion.
6. Align the orientation at and ow arrow parallel to the ow direction and proceed to insert the ow element into the process
media pipe up to the insertion depth mark.
7. Tighten the packing nut another ½ to 1 turn tight (approximately 20 ft-lbs) until the packing has created a full seal.
8. Ensure the locking collar is properly secured to the back of the packing gland. Torque the two No. 8-32 socket head cap
screws on the locking collar to 20 in-lbs using a 9/64″ hex key.
Retraction/Removal Procedure
1. Loosen the socket head cap screw on the side of the locking collar. See Figure F below.
Figure F
Caution: For applications where the process media is pressurized to greater than 232 psig [16 bar(g)] make sure to
rst depressurize the process line before retracting the ow element. At 232 psig [16 bar(g)], the effective force on the
insertion probe is 45.5 lbs (20.6 kg), which is the limit at which the ow element can be safely guided by hand. When
using hands to restrain the retraction, be prepared for a rapid pressure impulse of the ow element. Make sure that there
are no objects directly behind the ow element as the insertion probe may retract very quickly.
2. Slowly loosen the packing nut until the insertion probe begins to retract. Use hands as needed to help control the retraction.
If the probe does not begin to retract itself, gently shake and pull the insertion probe until the ow element has been fully
retracted into the packing gland.
3. For ball valve applications, close the ball valve immediately after retraction to seal off the process. After closing the ball
valve it is then safe to remove the ow element from the back end of the ball valve. If a ball valve is not being used, make
sure to rst depressurize the process line before removing the ow element.

Instrument Wiring
Before the instrument is opened to connect power and signal, FCI recommends that the following ESD precautions be observed:
Use a wrist band or heel strap with a 1 megohm resistor connected to ground. If the instrument is in the shop setting, there should be
a static conductive mat on the work table or oor with a 1 megohm resistor connected to ground. Connect the instrument to ground.
Apply antistatic agents such as Static Free made by Chemtronics (or equivalent) to hand tools to be used on the instrument. Keep high
static producing items away from the instrument.
The above precautions are minimum requirements. The complete use of ESD precautions can be found in the U.S. Dept of Defense
Handbook 263.
Warning: Only qualied personnel are to wire or test this instrument. The operator assumes all responsibility for safe
practices while wiring and troubleshooting.
Install an input power disconnect switch and fuse near the instrument to interrupt power during installation and
maintenance. Operator must have power disconnected before wiring.
See the “Specic Conditions of Use” and “Safety Instructions” sections in Appendix A for use of the ST51/ST75 series
(AC and DC versions) in Hazardous
Input Power
The ST51 is available with both VDC and VAC input power congurations. Customers selecting VDC input power will have
a VDC input board only
. Similarly, the VAC power board is supplied only with VAC powered units. In addition, both boards
are marked for either DC or AC power. Only connect the power specied on the wiring module as shown in Figures G and H
respectively. Both DC and AC inputs require a Gnd wire to be connected. Input power terminal blocks accept 14-26 AWG wire.
Make sure power is OFF before wiring the instrument. Pull the power and signal output wires through the port, using care not to
damage wires. FCI recommends using crimp lugs on the output wires to ensure proper connection with the terminal strip. Connect the
output wires as shown on Figures G and H. Note that when the 4-20 mA outputs are used simultaneously, a single return lead is used.
Analog Output
4-20mA: The instrument is provided with two 4-20 mA outputs. By default Output 1 is congured for ow and Output 2 is
congured for temperature. Terminal blocks accept 14-28 AWG wires, 500 ohms max. load per output.

Most entries require at least two key strokes; a capital letter and the [ENTER] key, or one or more numbers and the [ENTER] key.
All user entries begin at the input mode prompt “>”, except when the instrument is in the Main Function Mode (just press the
desired function letter and [ENTER] to make an entry).
Backspaces are made using the backspace [BKSP] key. Some entries are case sensitive between numbers and letters. Be sure the
SHIFT key is pressed to indicate the correct case. A square after the prompt caret indicates the FC88 is in lower case. A slightly
raised rectangle in the same spot indicates the FC88 is in the upper case.
It is recommended that the FC88 be plugged into the instrument before power is applied. If the FC88 is plugged in while the
instrument power is ON and the FC88 does not respond, press [ENTER]. If there is still no response press [N] or cycle the power.
Note: The Zero and Span may be changed from the original calibration, provided the new values are within the original
calibrated range; i.e., if the original calibration was 1 to 100 SCFM (4-20 mA), the new zero (4 mA) must be equal to or
greater than 1 SCFM, and the new span (20 mA) must be equal to or less than 100 SCFM.
Some entries require a Factory pass code. If this occurs contact FCI Field Service to continue programming the instrument. The
instrument will prompt the user when this is necessary. Do not change any parameters that require this code unless there is an
absolute understanding of the instrument’s operation. The user cannot exit some routines unless all entries are completed or the
power is cycled.

Maintenance
The FCI instrument requires little maintenance. There are no moving parts or mechanical parts subject to wear in the instrument. The
sensor assembly, which is exposed to the process media, is composed of 316 SS and Hastelloy C.
Without detailed knowledge of the environmental parameters of the application surroundings and process media, FCI cannot make
specic recommendations for periodic inspection, cleaning, or testing procedures. However, some suggested general guidelines for
maintenance steps are offered below. Use operating experience to establish the frequency of each type of maintenance.
Calibration
Periodically verify the calibration of the output and recalibrate if necessary. FCI recommends every 18 months at a minimum.
Note: Thirty (30) minute warm-up required before calibration check.
Electrical Connections
Periodically inspect cable connections on terminal strips and terminal blocks. Verify that terminal connections are tight and
physically sound with no sign of corrosion.
Remote Enclosure
Verify that the moisture barriers and seals protecting the electronics in the local enclosure is adequate and that no moisture is
entering the enclosure.
Electrical Wiring
FCI recommends occasional inspection of the system’s interconnecting cable, power wiring and ow element wiring on a
“common sense” basis related to the application environment. Periodically inspect the conductors for corrosion and check the
cable insulation for signs of deterioration.
Flow Element Connections
Verify that all seals are performing properly and that there is no leakage of the process media. Check for deterioration of the
gaskets and environmental seals used.
Insertion Type Flow Element Assembly
Periodically remove the ow element for inspection based on historical evidence of debris, foreign matter, or scale build-up and
appropriate plant shutdown schedules and procedures. Check for corrosion, stress cracking, and/or build-up of oxides, salts,

Troubleshooting
Application Verification
After verifying that the ow meter is functioning, review the application parameters as shown below to verify the calibration
matches the process media.
Equipment Needed
Flow Instrument Calibration Data
Process Parameters and Limits
Check Serial Numbers
Verify that the serial number of the ow element and the ow transmitter electronics are the same. The ow element and the ow
transmitter are a matched set and cannot be operated independently of each other.
Check the Instrument Installation
Verify correct mechanical and electrical installation. Verify the ow element is mounted at least 20 diameters downstream and 10
diameters upstream from any bends or interference in the process pipe or duct.
Check for Moisture
Check for moisture on the ow transmitter. Moisture may cause intermittent operation. Check for moisture on the ow element. If
a component of the process media is near its saturation temperature it may condense on the ow element. Place the ow element
where the process media is well above the saturation temperature of any of the process gases.
Check Application Design Requirements
Application design problems may occur with rst time application instruments, although the design should also be checked on
instruments that have been in operation for some time. If the application design does not match eld conditions, errors occur.
1. Review the application design with plant operation personnel and plant engineers.
2. Ensure that plant equipment such as pressure and temperature instruments conform to the actual conditions.
3. Verify operating temperature, operating pressure, line size, and gas medium.
Verify Standard Versus Actual Process Conditions
The ow meter measures the mass ow rate. The mass ow rate is the mass of the gas owing through a pipe per time. Other ow
meters, such as an orice plate or a pitot tube, measure the volumetric ow rate. The volumetric ow rate is the volume of gas per
time. If the readings displayed do not agree with another instrument, some calculations may be necessary before comparing them.
To calculate the mass ow rate, the volumetric ow rate, and the pressure and temperature, the point of measurement must be
known. Use the following equation to calculate the mass ow rate (Standard Volumetric Flow rate) for the other instrument:

Calibration Parameters Verification
The instrument uses a set of predetermined calibration parameters to process ow signals. Most of these parameters should not
change. A data package included with the instrument (typically on a CD-ROM) contains the ST51 Delta R Data Sheet. The data
sheet contains the calibration parameters stored in the ow transmitter at the factory. To verify that these parameters have not
changed, complete the following:
1. Identify the appropriate Delta R data sheets by instrument serial number.
2. Press [D] [ENTER] to examine each of the parameters. The [ENTER] key allows scrolling one message at a time. Use Table
