Fluid Components International ST50 User Manual
ST50 MASS FLOW METER
Installation and Operation Guide
Pre-Installation
The ST50 can be specified with integral or remote electronics. The flow element has a serial number etched into the side of the
extension pipe as shown on figure A. The transmitter circuit card has a serial number noted on the board as shown in figure B. The
flow 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 flow arrow indicator marked on the element assembly at the reference flat. These flow elements have
been calibrated in a particular direction and are designed to be used in service with the flow arrow facing in the same direction as
flow in the pipe stream. See Appendix C for orientation and factory calibration details.

Recommended Straight Run
To optimize flow 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 significantly reduce the available pipe diameters, FCI utilizes Vortab flow conditioners to produce a transferable flow profile from the calibration installation to actual field
installations. FCI’s proprietary AVAL software is available to make flow meter installation evaluations where straight run limitations
are considered. See Fig C for recommended installation.
Figure B
Figure C
FCI Flow Meters may be installed with less than the recommended straight run, but may have performance limitations. FCI offers
Vortab flow conditioners for use in applications that have significant 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 Vortab Flow Conditioning.

Installing Flow Element
Insertion Depth
Warning: The element is shipped with a protective sleeve surrounding the flow element. After removing the sleeve,
take care to prevent the element from sliding through the compression fitting and contacting the opposing wall with
any force as it may cause damage to the element and potentially upset the calibration.
The ST50 is available with both Teflon compression fitting ferrules and metal ferrules. While the Teflon ferrule configuration can
be readjusted, it is possible that over tightening may result in permanent positioning or damage to the extension pipe and will make
future adjustment difficult. While Teflon provides for some adjustability, it has a lower process pressure rating and is not designed
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 flow meters have been calibrated with the flow element located at the centerline of the pipe and flow 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 first installed in the line
with the compression fitting lightly tightened around the extension, then slowly move the pipe extension forward until the element is
at centerline as shown.
Warning: On top mount installations, particularly, take care to prevent the element from sliding through the compression fitting and contacting the opposing wall with any force as it may cause damage to the element and potentially
upset the calibration.

FLUID COMPONENTS INTERNATIONAL LLC ST50 MASS FLOW
To assist in final installation, FCI suggests making a readable mark on the extension pipe to indicate the final desired compression
fitting position that will place the element at the centerline reference once the system is tightened down into place. With the compression fitting lightly tightened , hold the element assembly along the outside of the installation, or directly above, to visually verify
the compression fitting location will ensure 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 fitting offset that
allows the compression fitting to securely seat in the process port. See Figure D above.
Align the flat parellel to flow and adjust the instrument depth. Upon determination of the final compression fitting location on the
extension pipe, apply the proper thread sealant to the NPT threads, firmly tighten the compression fitting 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.

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 megaohm resistor connected to ground. If the instrument is in the shop setting, there should
be a static conductive mat on the work table or floor with a 1 megaohm 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 Qualified personnel are to wire or test this instrument. The operator assumes all responsibility for
safe practices while wiring and trouble shooting.
FCI recommends installing and input power disconnect switch and fuse near the instrument to interrupt power during
installation and maintenance. Operator must have power disconnected before wiring.
Safety instructions for the use of the ST50 series (18 to 36VDC version only) in Hazardous Areas. Approval, KEMA
06ATEX0207 X for Category 3 GD protection EEx nA T6 T65°. Special conditions for safe use:
1) Provision shall be made to prevent the rated Voltage from being exceeded by transient disturbances of more than
40%.
2) For applications in explosive atmospheres caused by air/dust mixtures, cables and conduit entries shall be provided
a degree of protection of at least IP65 according to EN60529.
Input Power
The ST50 is available with both VDC and VAC input power configurations. 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 AC or DC power. Only connect the power specified on the wiring module as shown on Figures E and F respectively. Both VAC and VDC inputs require a Gnd wire to be connected. Input power terminal blocks are rated for 14-26 AWG.
To wire the instrument, ensure that the power is off. 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 E and F. Note that when the 4-20mA outputs are used simultaneously, a single return lead is
used.

The analog output configuration can be modified using three different methods:
1. The RS232 port, a FC88 hand held terminal and single letter commands as identified in Appendix A, table 5 of the Installation
and Operation Guide. The “V” command specifically configures the instrument analog outputs.
2. The RS232 port, a computer and the CLI commands as identified in Appendix A, table 6 of the Installation and Operation
Guide.
3. The PDA IR communication interface with version 1.11 software.
Pulse Output Activation
The ST50 provides a pulse output optional feature. Instruments ordered with this feature and volumetric or mass flow units will be
factory set with totalizer and pulse output activated. The mode can be changed in the field. Wiring either sink or source mode is
shown on page 7.
Source Mode: 15 VDC output, 50 mA max
Sink Mode: 40 VDC Max, 150 mA max. Customer supplied power source
Pulse Output Set up
The ST50 mass flow meter pulse output can be configured for either a pulse train (factory standard) for an external counter and/or
flow rate indication or an alarm. The pulses are available in 2 modes, Source and Sink. The maximum frequency of the pulse output
is 500Hz. The pulse output will only function after setup of the totalizer. After setup of the totalizer the pulse output needs to be
setup. During the pulse setup, the mode needs to be selected as well as the pulse factor, sample period and the pulse state
Source mode: In this mode the flow meter electronics will supply the voltage and current
for the pulse. Maximum 15 Vdc and 50mA (depends on the connected load).
Sink mode: If the connected load requires >15 Vdc and 50mA, an external power supply is required. Maximum 40 Vdc and
150mA
Pulse factor: Number of pulses per selected engineering unit. Default =1
Example in NCMH:
1 = 1 pulse per NCM
0.1 = 1 pulse per 0.1 NCM (10 pulses per 1 NCM)
10 = 1 pulse per 10 NCM
Range pulse factor 0.001 – 1000
Sample time: time in seconds before calculating the next number of pulses.
Pulse state: can be set High to Low or Low to High. Meaning the pulse is normally high or low

from high to low or low to high, depending on the selected pulse state, at a set flow rate. (pulse factor and sample
time not required).
Counter: can be set in Source and Sink mode. The NPN open collector will output the calculated number of pulses* calcu-
lated based on the indicated flow. And external display will indicate the totalized flow.
Flow rate: can be set in Source and Sink mode. The NPN open collector will output the calculated number of pulses* calcu-
lated based on the indicated flow. External display set to calculate flow from incoming pulses.

Menu Control and Organization
All user entries begin at the iput mode prompt “>”,except when the instrument is in the Main Function Mode. Most entries require at
least two key strokes; a Capital letter and the [ENTER] key, or one or more numbers and the [ENTER] key. If the unit is in the Main
Function Mode just press the desired function letter 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 (4-20mA), the new zero (4mA) must be equal to or greater than 1
SCFM, the new span (20mA) 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 can not exit some routines unless all entries are completed or the
power is recycled.
Caution: Always press “T” before unplugging the FC88. If a frozen meter display is observed, reconnect the FC88 and
wait 5 seconds for the meter to initialize. Disconnect the FC88 and confirm your meter display is varying.
