ST100A Series Flow Meter GENERAL
Fluid Components International LLC 1
1 GENERAL
Product Description
The ST100A Series is a thermal dispersion, industrial process grade air/gas flow meter. It is suitable for all air and gas flow measurement
applications in line sizes from 1" to 100" [25 to 2500 mm] and larger. The instrument provides direct mass flow measuring and measures flow rate,
totalized flow and temperature, and the STP versions add pressure measurement.
The measurements are made available to the user by way of 4-20 mA analog output channels with HART or pre-selected digital bus protocols. The
optional graphics display provides real-time process variable values along with flow range and process description information.
There are no moving parts to clean or maintain. A wide selection of process connections are offered to fit with any process piping. Versions are
available for temperature service from -40 °F [-40 °C] to 850 °F [454 °C].
The ST100A Series electronics/transmitter can be integrally mounted with the flow sensor or remote mounted up to 1000' [300m] from the sensor
element. Additional patented or FCI exclusive features include VeriCal® in-situ calibration verification, AST™ (patent pending) adaptive sensing
technology measuring technique, dual sensor/single transmitter models, and a built-in data logger capable of storing more than 20M readings. All
ST100A Series instruments are precision calibrated in FCI’s world-class, NIST traceable calibration facility on one of our flow stands matched to your
gas application and actual installation conditions.
Theory of Operation
The instrument is functionally based on the thermal dispersion operating principal. With AST™, power to the active RTD sensor’s heater is varied to
maintain a constant Delta T with the reference (unheated) RTD sensor. The flow rate and the heater power needed to maintain Delta T is
proportional. Once the heater current reaches a set maximum, the heater current is maintained as the instrument reads the varying sensor
resistance (Delta R). This resistance is proportional to flow rate. The transition between reading the heater power (constant Delta T) and reading the
sensor resistance (constant power) is seamless and automatic and is the key to the AST™ feature. The differential signal, whether it’s from the
sensor heater power (constant Delta T) or the sensor resistance (constant power) is scaled to drive a 4-20 mA flow output. A second temperature
output, from the unheated reference sensor, drives a second 4-20 mA output. A third 4-20 mA output is optional.
Safety Instructions
Warning:
Explosion Hazard. Do not disconnect equipment when flammable or combustible atmosphere is present.
●Field wiring shall be in accordance with NEC (ANSI-NFPA 70) or CEC (CSA C22.1) locations as applicable.
●Theinstrumentmust beinstalled,commissionedandmaintainedby qualifiedpersonneltrained inprocessautomationand control
instrumentation.Theinstallationpersonnel mustensure the instrument has been wired correctlyaccording tothe applicable wiringdiagram.
●All location specific installation and wiring requirements must be met and maintained. FCI recommends an input power circuit breaker
be installed between the power source and the flow meter. This facilitates easy power disconnection during commissioning and
maintenance procedures. Use a switch or circuit breaker if the instrument is in a hazardous area.
●The flow meter contains electrostatic discharge (ESD) sensitive devices. Use standard ESD precautions when handling the circuit
board assemblies.
●Hazardous Areas: The instrument is designed for use in hazardous areas. The approved area classification is identified on the
nameplate along with the temperature and pressure limitations. The USB port and the optional Ethernet port do not support the
hazardous area requirements and should only be used when the area is declassified. Remove any non-certified parts such as plastic
protection caps from cable entry ports and replace by suitable wiring and cabling system certified by notified bodies for use in
hazardous areas.
●When mounting the flow element into the process pipe, it is important that a lubricant/sealant is applied to the mating threads. Use a
lubricant/sealant that is compatible with the process media. Tighten all connections firmly. To avoid leaks do not overtighten or cross-
thread connections.
Order Verification
●Verify the received hardware matches the purchased hardware and application requirements. Verify the model/part number on the
instrument I.D. tag (e.g., ST100AL – 43E8000…) matches the purchased model/part number.
●Review the Calibration requirements as specified on the Engineering Data Sheet in the documentation package. Verify the flow,
temperature and pressure limits meet the application requirements.

Specific Conditions of Use
1. Consult the manufacturer if dimensional information on the flameproof joints is necessary.
2. The painted surface of the ST100A Series Flow Meter may store electrostatic charge and become a source of ignition in applications
with a low relative humidity < 30% relative humidity where the painted surface is relatively free of surface contamination such as dirt,
dust, or oil. Cleaning of the painted surface should only be done with a damp cloth.
3. Do not replace internal battery when an explosive gas atmosphere is present.
4. Refer to Appendix D, page 152, for details on the relationship between the temperature class, the maximum surface temperature, the
ambient temperature and the process temperature.
Instrument Identificationand Outline Dimensions
APPENDIX A starting on page 105 provides outline dimensions and mounting bracket dimensions for all integral and remote mounted electronic
configurations. Verify all dimensions meet the application requirements before beginning the installation process.
ST100A Insertion Sensor Installation
The proper flow meter location in the process piping configuration is critical to the instrument’s ability to measure the process variables accurately.
FCI recommends 20 nominal pipe diameters upstream and 10 pipe diameters downstream of the instrument installation point for most applications.
These distances can be significantly reduced when the flow meter is combined with FCI’s flow conditioning technology (Vortab).
Insertion flow elements can be mounted into the process using several available customer selectable configurations; compression fitting mounted,
threaded or flanged packing gland mounted, and threaded or flanged fixed “U” length mounted process connections. The specific sensor process
connection is specified by the customer on the order information sheet (OIS).
Mount the flow element to the process piping per the application piping requirements. Orient the instrument so that the flow arrow etched on the
element matches the direction of the process flow with the reference flat parallel to flow within ±3° of rotation. Insert a flow element with variable
insertion length ½” inch past the centerline of the process pipe or tube with the flow direction arrow correctly aligned and leveled. After the flow ele-
ment has been located correctly and tightened into place, verify that the process seal does not leak by slowly applying pressure until the maximum
operation pressure is applied. Check for leaks at the process connection boundary using standard leak detection methods.
Figure 1below shows a properly mounted compression fitting process connection instrument.

Compression Fitting
FCI single point insertion flowmeters are calibrated at the centerline of the process pipe. The flowelement is properly mounted when the
tip of the flowelement is located 0.50 inches (13 mm) past the pipe centerline. See Figure 2below. The scale etched on the side of the
insertion pipe indicates the length to the tip of the flow element. Follow the steps below to install the compression fitting flow element.
1. Calculate the insertion depth using the equation below.
I = Insertion depth

Retractable Packing Gland Mounting
A retractable low and medium pressure packing gland, with 1¼" MNPT threads or ANSI/DIN flange, and graphite or Teflon packing, is a
process connection option. FCI single point flow meters are calibrated at the centerline of the process pipe. The flow element is properly
mounted when the tip of the flow 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 (as applicable to your configuration, also follow the pipe thread or flange mount
procedures as described in previous sections).
Insertion/Installation Procedure
1. The scale etched on the side of the insertion probe indicates the length to the tip of the flow element. Calculate the insertion depth
using the equation, variables, and Figure 5below.
ID = Inside Diameter of Pipe
T = Pipe Wall Thickness
C = Mounting Coupling with Optional Ball Valve and Installed Packing Gland Length
INSERTION DEPTH = ______________
Figure 5 – Retractable Packing Gland Installation

ST100A Series Flow Meter INSTALLATION

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 as described
in the previous sections: Flange Mount and NPT Pipe Thread Mount. If a ball valve is not used, make sure to first depressurize
the process line before installing.
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 50 psig (3.5 barg), a medium pressure
packing gland assembly with support rods or FCI retractor tool, part no. 026854-01, must be used to safely insert the
probe into the process. The FCI packing gland and retractor tool are rated to a maximum pressure of 500 psig (35
barg). For instructions on how to install the flow meter using the FCI retractor tool, see step 7.
6. Manual Flow Element Insertion: Insertion by Hand (Pressure: 50 psig [3.5 barg] max.) or Using Med. Pressure Packing Gland
Assembly with Support Rods (Pressure: 500 psig [35 barg] max.)
a. Align the orientation flat and flow arrow parallel to the flow direction and proceed to insert the flow element into the process
media pipe up to the insertion depth mark. For medium pressure packing gland, use the adjusting nuts on the threaded rods to
pull the flow element up to the insertion depth mark, and then tighten the adjustable nuts against the adjustable support beam to
lock the insertion probe into place. Make sure to move the adjustable nuts at the same time (equally) to prevent the probe from
bending and damaging the packing gland.
b. Tighten the packing nut another ½- to 1-turn tight (approximately 65-85 ft-lbs [88-115 N-m]) until the packing has created a full seal.
c. Ensure the locking collar is properly secured to the back of the packing gland. Torque the two ¼"-28 socket head cap screws on
the locking collar to 94 in-lbs [11 N-m} using a 3/16" hex key.
7. Flow Element Insertion Using FCI Retractor Tool 026854-01 (Pressure: 500 psig (35 barg) max.)
a. Place the flow element into the top and bottom brackets of the FCI retractor tool as shown in Figure 6.
b. Align the orientation flat and flow arrow parallel to the flow direction. Position the top bracket close to the orientation flat as
shown in Figure 6.
c. Secure the top and bottom bracket clamps to the flow element using the eight no. 8-32 screws provided as shown in Figure 6.
Torque these screws to 20 in-lbs [2 N-m] minimum.
d. The retractor tool has, on both ends, a 3/8" drive socket that engages the retractor to move the flow element in or out. Once the
flow element has been properly secured, open the ball valve and insert the flow element by using either a hand wrench or a drill
to rotate either drive socket in the appropriate direction for insertion as shown in Figure 6. Observe the Warning below if using
an electric drill. Insert the flow element up to the insertion depth mark and tighten the packing nut another ½ to 1 turn tight
(approximately 65 to 85 ft-lbs [88-115 N-m]) until the packing has created a full seal.
Warning:
Take note of your environment if using an electric drill to operate the retractor. Do not use an electric drill in an
explosive environment as the drill could create a spark and cause an explosion.
e. Ensure the locking collar is properly secured to the back of the packing gland. Torque the two ¼"-28 socket head cap screws on
the locking collar to 94 in-lbs [11 N-m} using a 3/16" Allen wrench (hex key).
Note:
After insertingthe probe, you have theoption to leave the retractor tool inplace to easefuture proberemoval.If theretractor
toolisremoved,make suretoreinstall itbefore retractingthe probeat pressures>50 psig. Sincethe packinggland itself
has a 500 psig rating, the probe remains securely in place with the retractor off.

Figure 6 – Flow Element Installation Using FCI Retractor Tool 026854-01
Retraction/Removal Procedure
Caution: For applications where the process media is pressurized to greater than 50 psig (3.5 barg), FCI retractor tool, part no.
026854-01, must be used to safely retract the probe from the process (does not apply to applications using the
medium pressure packing gland assembly with support rods). For applications where the process media is
pressurized to equal to or less than 50 psig (3.5 barg), the flow element can be safely guided by hand. When using
hands to restrain the retraction, be prepared for a rapid pressure impulse of the flow element. Check first that there
are no objects directly behind the flow element as the insertion probe may retract very quickly.
1. Manual Flow Element Retraction: Retraction by Hand (Pressure: 50 psig [3.5 barg] max.) or Using Med. Pressure Packing
Gland Assembly with Support Rods (Pressure: 500 psig [35 barg] max.)
a. Loosen the socket head cap screw on the side of the locking collar. See Figure 7 below.
Figure 7 – Packing Gland Locking Collar
b. Low Pressure (max. 50 psig [3.5 bar(g)]): 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 flow element has been fully retracted into the packing gland.
