ST75/ST75V MASS FLOW METER
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 tag on the enclosure will also denote serial number and model number. 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 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.

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 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.
Analog Output
4-20mA: The instrument is provided with a standard set up, of two 4-20mA outputs. Output 1 configured for flow and Output 2
configured for temperature. Terminal blocks rated for 14-28 AWG., 500 ohm 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 (4-20mA), 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.

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 the conductors should be inspected for corrosion and the cable
insulation checked 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:

The ST75/ST75V Flowmeter is comprised of 4 basic components:
1. Sensor element.
2. Customer interface circuit board
3. Control circuit assembly circuit board module.
4. Electronics enclosure.
Step 1
Verify fuse (F1) located on the customer interface circuit board is in normal working condition.
Remove power from the instrument. Open the electronics enclosure exposing the customer interface circuit board. This circuit board
is located under the shorter enclosure lid along with all of the power and input/output connections. Unscrew the clear cover on the
fuse and pull the fuse out of the fuse holder. Check the fuse for continuity. If fuse reads open, replace with equivalent component

Goods furnished by the Seller are to be within the limits and of the sizes published by the Seller and subject to the Seller’s
standard tolerances for variations. All items made by the Seller are inspected before shipment, and should any of said
items prove defective due to faults in manufacture or performance under Seller approved applications, or fail to meet the
written specifications accepted by the Seller, they will be replaced or repaired by Seller at no charge to Buyer provided
return or notice of rejection of such material is made within a reasonable period but in no event longer than one (1) year for
non-calibration defects and one (1) year for calibration defects from date of shipment to Buyer, and provided further, that
an examination by Seller discloses to Seller’s reasonable satisfaction that the defect is covered by this warranty and that
the Buyer has not returned the equipment in a damaged condition due to Buyer’s or Buyer’s employees’, agents’, or
representatives’ negligence and Buyer has not tampered, modified, redesigned, misapplied, abused, or misused the goods
as to cause the goods to fail. In addition, this warranty shall not cover damage caused by Buyer’s exposure of the goods to
corrosive or abrasive environments. Moreover, Seller shall in no event be responsible for (1) the cost or repair of any work
done by Buyer on material furnished hereunder (unless specifically authorized in writing in each instance by Seller), (2) the
cost or repair of any modifications added by a Distributor or a third party, (3) any consequential or incidental damages,
losses, or expenses in connection with or by reason of the use of or inability to use goods purchased for any purpose, and
Seller’s liability shall be specifically limited to free replacement, or refund of the purchase price, at Seller’s option, provided
