A. Introduction
1. Unpacking
McMillan suitably packages all sensors to prevent damage during shipping.
If external damage is noted upon receipt of the package, please contact
the shipping company immediately. McMillan Company is not liable for
damage to the device once it has left the manufacturing premises.
Open the package from the top, taking care not to cut too deeply into the
package. Remove all the documentation and contents. Take care to
remove all the items and check them against the packing slip. The
products should also be checked for any concealed shipping damage. If
any shortages or damage is noted, please contact the shipping company
and/or McMillan Company to resolve the problem.

Caution: Take care not to
drop your sensor or subject it to
sudden impact. Read the installation section of this manual
before providing power or tubing connections to the unit. Any
damage caused by improper installation or careless handling will
not be repaired under warranty (see limited warranty on page 30
for more details).
2. Product Overview and Principle of Operation
McMillan Micro Turbine Wheel FLO-SENSORS®for gases are capable of
measuring volumetric flows as low as 20-100 ml/min or as high as 100-
500 l/min. Highly repeatable results are achieved using a patented Pelton
Turbine Wheel flow sensor design. This proven design minimizes zero drift

100-M004, pg. 4 of 36
while maintaining fast response and linear outputs with virtually no
maintenance.
McMillan’s patented technology
measures flow using a miniature
turbine wheel similar in size to a
U.S. dime (16 mm diameter,
0.75 mm thick). The micro-
turbine wheel is supported on a
very small sapphire shaft that is
held in position by two sapphire
bearings.
As flow passes through the FLO-
SENSOR®, a precision machined
nozzle directs the gas onto the
very small teeth of the micro-
turbine wheel. This causes the wheel to spin at a speed proportional to the
volumetric flow rate.
The micro-turbine wheel has alternating white and black sections evenly
spaced on one side of the wheel. An infrared light beam is directed onto
the wheel. As the wheel rotates the infrared beam is reflected off each
white section. The reflected beam is detected by a phototransistor that
converts the reflections into electrical pulses. As the wheel spins faster the
pulse rate increases. Processing circuitry provides analog and/or pulse
output that are linearly proportional to the volumetric flow rate
When the wheel stops (under zero flow conditions), no pulses are
generated. Consequently, zero drift is not possible and zero adjustments
are never required.
Every unit is supplied with a calibration certificate detailing the results
obtained during calibration. Units are calibrated using AIR as the reference
media. Flowing gases with different physical characteristics may effect the
calibration.
3. Non-Standard Products (Z Suffixes)
Please note that the installation instructions, operating instructions, and
specifications included within this manual apply to standard production
models only. If your FLO-SENSOR® or FLO-METER®has a “Z” suffix (e.g.
100-
Z0123 ) then your unit is non-standard. Contact the factory to check if
the installation, operation, or specifications of your sensor are different
than detailed in this manual.
B. Installation
Caution: Do not exceed the pressure, temperature or
power operating ranges detailed in the SPECIFICATIONS
section of this manual. McMillan Company shall not be
liable for any damage or injury caused by incorrect
operation of their products.

100-M004, pg. 5 of 36
1. General Considerations
It is recommended that a safety shut-off valve be installed upstream of
(before) the sensor.
All wetted parts should be checked for compatibility with the gas to be
used. If there are any incompatibilities eg. highly corrosive gas, then the
unit may be damaged or fail prematurely. Such damage will not be
repaired under warranty.
Units should be installed in a clean, dry environment with an ambient
temperature that is as stable as possible. Avoid areas with strong magnetic
fields, strong air flows or excessive vibration.
If the gas to be used may contain particles larger than 25 microns then a
filter (25 microns or less) should be installed upstream of (before) the unit.
2. Mounting the FLO-SENSOR®or FLO-METER®.
Caution: On high flow units (2.0-10.0 L/min, range 9,
and above) DO NOT disassemble the shunt / mounting
plate assembly or the unit will not operate correctly and
the warranty will be void.
McMillan FLO-SENSORS®and FLO-METERS®have no particular installation
requirements so may be mounted in any convenient position. For optimum
results the unit should be mounted with the mounting feet horizontal on
top of a flat horizontal surface. This is the same position that the unit is
calibrated in at the factory. Please contact the McMillan Service
Department if calibration for mounting in another orientation is desired.
It is recommended that units be fixed to a suitable substrate with #4
screws using the two mounting holes provided.

100-M004, pg. 6 of 36
3. Tubing Connections
CAUTION: DO NOT FLOW ANY LIQUID THROUGH A GAS
FLO-SENSOR®OR FLO-METER®. THIS WILL SERIOUSLY
EFFECT THE PERFORMANCE AND VOID THE WARRANTY.
CAUTION: DO NOT FLOW A HIGH PRESSURE GAS
THROUGH THE SENSOR. A BURST OF HIGH PRESSURE
GAS MAY CAUSE THE UNIT TO BE DAMAGED. ALWAYS
FLOW GAS AT A PRESSURE AND FLOW RATE WITHIN
THE SPECIFCATIONS OF THE UNIT
All tubing must be clean, dry and without crimps, burrs or scratches.
Only use the factory installed fittings on the unit. If the fittings are
removed the calibration of the unit may be effected and leaking may
occur. If different fittings are required please contact the McMillan
Company Service Department for assistance.
When connecting the sensor to the tubing a wrench should be used to
stop the fitting rotating in the sensor body. Take care not to over tighten
the fittings or leaking may occur.
Connecting and tightening the Fittings
(S Series shown, other models similar)
Caution: DO NOT over tighten the fittings into the FLO-
SENSOR®or FLO-METER®body. Excessive force may
damage the sensor body. This type of damage will NOT
be repaired under warranty.

100-M004, pg. 7 of 36
The flow direction for the FLO-SENSORS®or FLO-METERS®is clearly
marked on the label. Do not reverse the flow direction or the unit will not
function correctly.
Close Up of Label Showing Flow Directions
(Model 101 shown, other models similar)
The tubing ID should be as large as possible to avoid restrictions and
turbulence. For the best results, a straight length of tubing before the unit
is recommended. This should be 20 times the tubing I.D. or greater
4. Electrical Connections
Caution: Incorrect wiring may cause severe damage to the unit.
Applying an AC voltage (115VAC or 230VAC) directly to the unit
will cause damage. Read the following instructions carefully
before making any connections.
a) Overview
McMillan FLO-SENSORS®for gases provide a 0-5VDC output proportional
to the volumetric flow rate. This output may be connected to a display,
data acquisition system or voltmeter. The Model 110, S-110 and S-113
FLO-METERS®feature an integral display that provides a local flow
reading. These units also have a 0-5VDC analog output available. If
required, this may be connected to another display, data acquisition
system or voltmeter.
A stable D.C. power supply is required to operate the unit. The voltage
and current requirements depend on the configuration of the unit. Full
details may be found in the Specification section of this manual.

100-M004, pg. 8 of 36
Connecting wires should be as short as possible to avoid voltage drops.
Twisted 2 pair conductor cable of a suitable gauge should be used if the
length of the power wires is to be longer than 1 meter (3.2 feet).
Units are supplied with an integral 4 pin connector. Connections to the unit
are made using a mating cable assembly or power adapter package as
detailed in the following sections. A connector pin and wire color cross
reference may also be found in Appendix H (Page 20) of this manual.
b) Connecting a Cable Assembly
The connector on the end of the cable assembly should be pushed into the
mating socket on the sensor taking care to ensure that it is the correct
way up.
Connecting the Cable Assembly
(Model 101 shown, other models similar)
Electrical connections to the cable assembly are made as detailed in the
following sections.

100-M004, pg. 9 of 36
c) Electrical Connections – Voltage Output Units
The cable assembly should be connected to the sensor as detailed in
section 5(b) above. Do not apply power to the sensor until all the
connections have been made and checked. Electrical connections should
be made as follows:
Wiring Schematic For Voltage Output Units.
The RED wire should be connected to the Positive of the power source.
The BLACK wire should be connected to the Negative ( Ground ) of the
power source.
The WHITE wire provides the signal output and should be connected to
the positive terminal of the display, data acquisition system or voltmeter
with an impedance greater than 2500Ω(Ohms).
The GREEN wire is not used.
Caution: Avoid high voltage static discharges to any of the
connections. Do not short the input/output signal wires or allow
them to contact the power wires at any time. DAMAGE WILL
RESULT!

100-M004, pg. 10 of 36
d) Using a 0-5VDC Output Power Adapter Package.
An optional 0-5VDC Output Power Adapter Package is available for use
with the Model 100, S-110 and S-113. The Model 110 is supplied complete
with a 0-5VDC Output Power Adapter Package.
The 0-5VDC Output Power Adapter Package consists of a power source
(115VAC or 230VAC) and cable assembly with pig-tail (soldered wire) ends
for the signal output. This should be assembled as shown in the following
diagram.
Connecting the Power Adapter to the Flow Sensor
(Model 100 shown, other models similar)
The 0-5VDC analog output may be connected to a display, data acquisition
system or voltmeter with a minimum load of 2.5 kΩ(kilo ohms).
The YELLOW wire of the cable assembly provides the 0-5VDC signal
output and should be connected to the positive terminal of the display,
data acquisition system or voltmeter.
The GREEN wire is not used.
The WHITE wire of the cable assembly is the signal negative and should
be connected to the negative (ground) terminal of the voltmeter, display
or data acquisition system.
Caution: Avoid high voltage static discharges to any of the
connections. Do not short the output signal wires or allow them
to contact the power wires at any time. DAMAGE WILL RESULT!

100-M004, pg. 11 of 36
e) Using a 4-20mA Output Signal Converter Package
(D-24 VDC).
An optional 4-20mA Output Signal Converter Package is available for use
with the Model 100, S-110 and S-113. This consists of a signal converter, a
cable assembly to connect the converter to the sensor and a cable
assembly to connect to the 4-20mA (active current) output signal. The
signal converter requires 24VDC power to operate. This package should be
assembled as shown in the following diagram.
Assembling the D-24VDC 4-20mA Signal Converter Package
(Model 101 shown, other models similar)
i) Electrical connections to the FLOW SENSOR cable assembly
The RED wire should be connected to PIN 4 of the signal converter
unit.
The BLACK wire should be connected to PIN 2 of the signal
converter unit.
The WHITE wire should be connected to PIN 3 of the signal
converter unit.
The GREEN wire (if present) is NOT used
ii) Connecting a power supply.
A stable low noise 18-24 VDC power supply should be connected to
the signal converter as follows:
PIN 1 of the signal converter unit should be connected to the
Positive of the power source.
PIN 2 of the signal converter unit should be connected to the
Negative (Ground) of the power source.

100-M004, pg. 12 of 36
iii) Electrical connections to the 4-20mA FLOW SIGNAL OUTPUT cable
assembly:
The CENTER wire of the cable assembly provides the 4-20mA (active
current) signal output and should be connected to the positive
terminal of the display, data acquisition system or current meter with
an impedance of 0 - 500Ω(Ohms).
The SHIELD wire of the cable assembly is the signal negative and
should be connected to the negative (ground) terminal of the current
meter, display or data acquisition system.
Caution: Avoid high voltage static discharges to any of the
connections. Do not short the output signal wires or allow them
to contact the power wires at any time. DAMAGE WILL RESULT!
C. Operation
CAUTION: DO NOT FLOW ANY LIQUID THROUGH A GAS
FLO-SENSOR®OR FLO-METER®. THIS WILL SERIOUSLY
EFFECT THE PERFORMANCE AND VOID THE WARRANTY.
1. Start Up
Before applying power to the unit check all tubing and electrical
connections. Once correct installation is verified switch on the power.
2. Flow Readings
The McMillan Model 100 FLO-SENSOR®for gases provides a 0-5VDC
output proportional to the volumetric flow rate.
The Model 110, S-110 and S-113 FLO-METERS®feature an integral 3.5
digit display that provides a local flow reading and a 0-5VDC analog output
proportional to the volumetric flow rate.
Each FLO-SENSOR®or FLO-METER®is factory calibrated for a specific flow
range. The flow range is shown on the unit’s label and calibration
certificate. Units are calibrated using AIR as the reference media unless
otherwise noted. Calibrations are carried out with the mounting feet
horizontal on a flat horizontal surface.
a) 0-5VDC Analog Outputs
By monitoring the voltage output signal it is possible to determine the flow
rate of the gas. Units are configured so that an output signal of 5.0VDC is
provided when the maximum flow (i.e. Full Scale flow) is passing through
the unit. The output signal is linear and scaleable enabling calculation of
flow rates within the sensor’s range.

100-M004, pg. 13 of 36
For example:
For a flow range of 100-500ml/min (Range 5) :
At 500ml/min the output signal would be 5VDC
If the output signal were 3.5VDC then the flow rate would be:
(500 ÷ 5) × 3.5 = 350ml/min
If the maximum flow rate is exceeded non-linear and inaccurate readings
will result.
b) 4-20mA Outputs (Using the 4-20mA Signal Converter)
By monitoring the current output signal it is possible to determine the flow
rate of the gas. Units are configured so that an output signal of 20mA is
provided when the maximum flow (i.e. Full Scale flow) is passing through
the unit. The output signal is 4mA when flow is at or below the specified
low flow rate for the unit. The output signal is linear and scaleable
enabling calculation of flow rates within the sensor’s range. For example:
For a flow range of 2.0-10.0l/min (Range 9) :
At 10.0l/min the output signal would be 20mA
If the output signal were 9mA then the flow rate would be:
[10.0 ÷ (20-4)] × 9 = 5.63l/min
c) Units With an Integral Display
The Model 110, S-110, and S-113 feature an integral 3 ½ digit LCD
display. This is configured to read in ml/min for flow ranges 2-5 and in
l/min for flow ranges 6-14. The display will only operate if power is applied
to the unit.
Flow readings may be taken directly from the display or by monitoring the
0-5VDC analog output provided (see above).

3. Operating at Flow Rates Outside the Calibrated Flow Range
CAUTION:. If the flow through the unit exceeds 120% of
the maximum rated (full scale) flow the unit may be
damaged. This type of damage will not be repaired under
warranty.
Flow measurement is only accurate within the calibrated flow range for the
unit. This is detailed on the calibration certificate. The unit will still
operate, to some degree, outside this flow range.
Results obtained when operating outside the specified range of the unit
are not accurate but may be considered repeatable.
a) Flows Above the Maximum Rated Flow.
If the flow rate is above the maximum rated (or full scale) flow, the unit
will still operate and provide an output signal proportional to the flow rate.
Flows must not exceed 120% of the maximum rated flow or the unit may
be damaged.
b) Flows Below the Minimum Rated Flow.
Signal outputs may be obtained at flow rates below the minimum specified
for your unit. The amount of flow that may be measured below the
minimum specified varies from unit to unit.

100-M004, pg. 15 of 36
4. Zero Adjustments
It is impossible for there to be any zero drift so zero adjustments are
never required.
5. Recalibration
Please contact the McMillan Service Department if your FLO-SENSOR®or
FLO-METER®needs recalibration.
6. Using FLO-SENSORS®or FLO-METERS®with Different Gases
McMillan FLO-SENSORS®or FLO-METERS®will operate with most gases
subject to compatibility of the wetted parts.
For information about
calibrating for Hydrogen or Helium, contact the McMillan Service
Department.
Units are calibrated with AIR at a pressure of 760mmHg and temperature
of 23°C unless otherwise detailed on the calibration certificate. Using other
gases will effect the calibration. The amount of calibration error will
depend on the characteristics of the gas being flowed.
The flow reading correction factor (or calibration factor) may be
approximately calculated with the following formula:
Cf= ( Snew ÷ Scurrent )0.3
Cf= Correction factor
Snew = Specific gravity of new gas
Scurrent = Specific gravity of original calibration gas
A corrected flow reading may then be calculated using the correction
factor as follows:
Corrected Flow = Flow reading X Correction Factor
For example, if the unit is calibrated for AIR but the user wants to
measure the flow of Carbon Dioxide (CO2) with a specific gravity of 1.517
the flow reading correction factor would be calculated as follows:
Snew = Specific gravity of CO2= 1.517
Scurrent = Specific gravity of Air = 1.000
Cf= (Scurrent ÷ Snew)0.3
Cf= ( 1.000 ÷ 1.517 )0.3
Cf= 0.88

100-M004, pg. 16 of 36
If the unit has a flow reading of 200ml/min then the corrected flow
reading (for CO2) would be:
Corrected Flow = 200 X 0.88 = 176 ml/min
CAUTION:. The use of correction factors can be subject
to inaccuracy and errors of up to ±10%. Please contact
the McMillan Service Department if accurate, certified
recalibration is required.
Calculating a correction factor for a gas enables the calibration of the unit
to be adjusted for that gas. This is accomplished by:
i) Calculate the corrected flow reading or VDC output at 100% of
flow using the above formulas.
ii) Adjust the flow of (the new) gas to give this flow reading
iii) Maintain this flow and ensure a stable reading.
iv) Adjust the gain potentiometer on the unit so that a 5VDC output
is obtained. The unit is now calibrated for the new gas.
For example: A 2.0 -10.0 l/min unit that has been calibrated for Air is to
be used with CO2. The correction factor, calculated as above, is 0.88.
When flowing CO2the unit will read high i.e. at 5VDC the flow of CO2
would actually be 8.8 l/min and not 10 L/min. A flow of 10 l/min of CO2
through the unit would give a reading of 10/0.88 = 11.36 l/min or 5.68
VDC on the unit. Flow should be adjusted so that an output of 5.68VDC or
reading of 11.36l/min is obtained. The gain potentiometer is then adjusted
so that the voltage output becomes 5VDC or the display reads 10l/min.
The unit has now been adjusted for CO2and no further corrections to flow
readings are required (if flowing CO2).
It should be noted that the maximum output voltage for the units is
approximately 5.9VDC. It is not possible to adjust units if an output of
greater than 5.9 VDC is required.

D. Maintenance and Product Care
1. General
CAUTION: Do not disassemble your FLO-METER®or FLO-
SENSOR®for any reason. If the unit appears to be
malfunctioning please contact the McMillan Service
Department.
McMillan FLO-SENSORS®and FLO-METERS®require no periodic
maintenance if used within the recommended specifications.
The next recommended recalibration date is stated on the calibration
certificate supplied with the unit. Please contact the McMillan Service
Department for further information.
Inlet filters should be periodically checked and cleaned / replaced as
necessary.
Regularly check all electrical and process connections for damage or
deterioration.
If the sensor is to be stored, keep both the inlet and outlet ports sealed.
2. Cleaning and Flushing
If there is a build up of deposits or particles from the measured gases it
may be necessary to clean
or flush the unit. This should be done by
flowing clean, particle free air (or Nitrogen) through the unit at a flow rate,
pressure and temperature within the specifications of the unit. If
necessary, flow may be reversed to assist flushing.
CAUTION: Do not flow a high pressure gas through the
sensor. A burst of high pressure gas may cause the
turbine wheel sensor to be damaged. Always flow gas at
a pressure and flow rate within the specifications of the
unit
3. Returning Units for Repair or Recalibration
To return a unit for repair or recalibration please contact the McMillan
Service Department or follow the procedure detailed on the McMillan web
site. A Return to Manufacturer Authorization (RMA) number will then be
issued to enable the unit to be returned. Please note that no returns will
be accepted unless the RMA number is clearly indicated on the outside of
all packages.
Once the unit has been received it will be evaluated and the cost of any
repairs / recalibration determined. Once agreement has been received to
pay for all the necessary work the unit will be processed and returned. No
charges will be made for Warranty Repairs (see section I).
