Installation and Operation Guide
Pre-Installation
Serial Number Alignment
The ST75 and ST75V (Vortab) can be specified with integral or remote electronics. The flow element has a serial number etched
into the side of the HEX as shown on Figure A. In addition, the enclosure tag also shows serial and model numbers. The associated
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 HEX flat. These flow elements have
been calibrated in a particular direction and are designed to be used in service with the flow arrow going in the same direction as flow in
the pipe stream. The flow element has been calibrated directly in the pipe tee or tube tee with careful consideration for orientation and
insertion depth. Removal from the tee section while physically possible is not recommended unless authorized by a factory technician.

Recommended Straight Run
To optimize flow meter system performance, FCI recommends installation with a minimum of 20 diameters upstream straight run
and 10 pipe diameters of downstream straight run. Where straight run limitations significantly reduce the available pipe diameters,
FCI utilizes 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
Figure C for recommended installation.

Instrument Wiring
Before opening the instrument to connect power and signal observe the following ESD precautions:
Use a wrist band or heel strap with a 1 megaohm resistor connected to ground. If the instrument is in the shop setting, use 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.
See Safety instructions in Appendix A for the use of the ST75/ST75V series (AC and DC versions) in Hazardous Areas

T6..T1, Ex tD A21 IP67 T 90°C...Τ 121°C.
Input Power
The ST75/ST75V 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 accept 14-26 AWG wire.
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 4-20 mA outputs are used simultaneously, a single return lead is used.
Analog Output
4-20 mA: The instrument is provided with a standard set up, of two 4-20 mA outputs. Output 1 is configured for flow and Output 2 is
configured for temperature. Terminal blocks accept 14-28 AWG wire, 500 ohms max load per output.

Menu Control and Organization
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, 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 recycled.
The top level of the menu is shown in Appendix B - Table 5. Enter the large letter in the tables below to activate a command. The user
may exit a command at any time entering “Q” [ENTER] in the menus: D, K, V, W, or Z.

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
specific 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.
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 flow 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 flow 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, or foreign
substances. The thermowells must be free of excessive contaminants and be physically intact. Any debris or residue build‑up could
cause inaccurate flow indication. Clean the flow element, as necessary, with a soft brush and available solvents (compatible with
Stainless Steel).

Troubleshooting
Application Verification
After verifying that the flow 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 flow element and the flow transmitter electronics are the same. The flow element and the flow
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 flow 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 flow transmitter. Moisture may cause intermittent operation. Check for moisture on the flow element. If a
component of the process media is near its saturation temperature it may condense on the flow element. Place the flow 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 first 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 field 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 flowmeter measures the mass flow rate. The mass flow rate is the mass of the gas flowing through a pipe per time. Other flow meters,
such as an orifice plate or a pitot tube, measure the volumetric flow rate. The volumetric flow 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 flow rate, the volumetric flow rate, and the pressure and temperature, the point of measurement must be known. Use the following
equation to calculate the mass flow rate (Standard Volumetric Flow rate) for the other instrument:
Equation:
P
T
QS = Q A × A × S
TA
PS
Where:
QS= Standard Volumetric Flow
QA= Volumetric Flow
PA= Actual Pressure TA= Actual Temperature
PS= Standard Pressure TS= Standard Temperature
PSIA and °R are used for pressure and temperature units.
(Metric: Where bar(a) and °K are
used for pressure and temperature.)
Example:(Metric: PS = 1.01325 bar(a)
QA= 1212.7 ACFM
QS= 1485 SCFM
TS = 21.1°C (294.1K))
PA= 19.7 PSIA TA= 120 °F (580 °R)
