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 37
for more details).

Product Overview and Principle of Operation
McMillan Micro Turbine Wheel FLO-SENSORS® for liquids are capable of
measuring flows as low as 13-100 ml/min or as high as 1.0-10.0 l/min.
Highly repeatable results are achieved using a patented Pelton Turbine
Wheel flow sensor design. This proven design minimizes zero drift while
maintaining fast response and linear outputs with virtually no
maintenance.
101-M002, pg. 3 of 42
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. The micro-turbine assembly is
so light that it virtually floats in the liquid. This relieves force on the
bearings and almost eliminates wear.
As flow passes through the FLO-SENSOR®, a precision machined nozzle
directs the fluid onto the very small teeth of the micro-turbine wheel. This
causes the wheel to spin at a speed proportional to the 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 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 deionized water as
the reference media. Flowing liquids with different specific gravities or
viscosities 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.
101-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.
101-M002, pg. 4 of 42
Installation
CAUTION: Do not flow any gas through a liquid FLOSENSOR® or FLO-METER®. This may damage the microturbine assembly and void the warranty. 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.
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 liquid to be
used. If there are any incompatibilities e.g. highly corrosive liquid, 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 liquid 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.
The required differential press (or pressure drop across the unit)
decreases exponentially with decreases in flow rate.

101-M002, pg. 5 of 42
To calculate the pressure drop at a certain flow rate use the formula
PD = (YourFlow / MaxFlow)2 x PDmax
PD = Pressure drop at YourFlow.
YourFLow = flow rate (ml/min or l/min)
MaxFlow = 100% rated flow for the sensor (in same units as
YourFlow)
PDmax = Pressure drop at 100% rated flow (see chart above)
If the pressure available for the flow sensor is BELOW the pressure drop at
the required flow then flow through the unit will not be possible.
For example: You have a sensor with a 50-500ml/min flow range (Range
5) and want to know the pressure drop (or minimum differential pressure
required) at 300ml/min. According to the chart above, the pressure drop
at 100% of flow is approx 10psi. Using the formula above:
PD = (300 / 500)2 x 10 = 3.6 psid
Therefore, at 300ml/min the minimum required differential pressure for
this unit is 3.6 psid. This means that if the available pressure is below
3.6psid then flow through the unit may not be possible.
Pressure drop through a system is cumulative. If the total pressure drop
across all the components in a system exceeds the minimum pressure
available then flow will not be possible.
For example: A system has a pressure of 30-40psi. There are several
components and the sum of their pressure drops at the required flow rate
is 32psid. If the system is operating at 30psi flow would not be possible as
the total of the pressure drops would be greater than the pressure
available. The system will only operate if the system pressure is above
32psi.
If there is any possibility that there may be bubbles or entrapped gas in
the system then the outlet tubing should be elevated above the inlet port.
This will enable any gas that may become entrapped in the unit to escape
(see section C2 for details of how to remove entrapped air or gas).
2.
Mounting the FLO-SENSOR® or FLO-METER®.
McMillan FLO-SENSORS® and FLO-METERS® have no particular installation
requirements so may be mounted in any convenient position.
It is recommended that units be fixed to a suitable substrate with #4
screws using the two mounting holes provided.
101-M002, pg. 6 of 42
Mounting The Sensor
(mounting hardware not included with sensor)
3.
Mounting a FLO-METER® Using an Optional Base-plate (S-111
only).
An optional mounting base-plate (Part Number 110-00-17) is available for
the Model S-111 FLO-METER®. This enables easy installation on flat, level
surfaces.
The FLO-METER® and base-plate should be assembled using the screws
provided.

Tubing Connections
CAUTION: DO NOT FLOW ANY GAS THROUGH A LIQUID
FLO-SENSOR® OR FLO-METER®. THIS WILL DAMAGE THE
MICRO-TURBINE ASSEMBLY AND VOID THE WARRANTY.
All tubing must be clean and without crimps, burrs or scratches.
Only use the fittings factory installed 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 FLOSENSOR® or FLO-METER® body. Excessive force may
damage the sensor body and will NOT be repaired under
warranty.
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.
101-M002, pg. 8 of 42
Close Up of Label Showing Flow Directions
(Model 101 shown, other models similar)
For the best results precautions should be taken to minimize the amount
of turbulence in the flow stream. Avoid valves, fittings, curves in the tube,
changes in the internal diameter or any other restrictions close to the inlet
of the sensor. The tubing ID should be as large as possible and preferably
not smaller than the ID of the fittings installed on the sensor.
For 0.2-2.0 L/min (Range 7) units a 10 cm straight length of tube before
the sensor is recommended. For higher flow range units (0.5-5.0 L/min
and 1.0-10.0 L/min), a 20 cm straight length of tubing before the sensor is
recommended. If this is not possible it is recommended that straight
lengths between all connections on the inlet side of the sensor are as long
as possible and 90 degree fittings (with a large enough ID) are used
instead of curves in the tubing.
5.
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.

C.
Operation
CAUTION: USE WITH LIQUIDS ONLY. FLOWING GAS OR
AIR THROUGH YOUR FLO-SENSOR® OR FLO-METER®
WILL DAMAGE THE MICRO-TURBINE ASSEMBLY. THIS
TYPE OF DAMAGE WILL NOT BE REPAIRED UNDER
WARRANTY.
101-M002, pg. 18 of 42
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.
Entrapped Air or Gas
There may be a lot of air or gas trapped in your FLO-SENSOR® or FLOMETER® after installation. This will usually escape the unit when flow
(within the range of the unit) is first started.
Caution: The system should be primed with liquid and flow
started gradually. This will prevent trapped air or gas from being
forced through the sensor at a high velocity that may damage
the sensor.
If gas remains entrapped in the unit it may be necessary to elevate the
outlet tubing above the inlet of the FLO-METER® or FLO-SENSOR®. This
should enable the trapped gas to escape the unit. The FLO-SENSORS® or
FLO-METERS® may be returned to it’s original position once all the gas has
escaped.
If elevating the outlet tubing does not work, block or pinch the outlet tube
whilst there is flow in the system. After approximately 5 seconds, release
the restriction to allow normal flow. Doing this will build up pressure in the
flow path that when released will help remove the entrapped gas. Repeat
this until the entrapped gas is removed form the unit.
3.
Flow Readings
McMillan FLO-SENSORS® provide a 0-5VDC, or 4-20mA, or 0-5VDC and
pulse output (T option) proportional to the flow rate. The type of output
signal is detailed in the part number reference and on the calibration
certificate.
The Model S-111, S-112 and S-114 FLO-METERS® feature an integral
display that provides a local flow reading and a 0-5VDC analog output.
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 deionized water as the reference
media.
a)
0-5VDC Analog Outputs
By monitoring the voltage output signal it is possible to determine the flow
rate of the liquid. 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. For example:
101-M002, pg. 19 of 42
For a flow range of 50-500ml/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)
Pulse Outputs
By monitoring the Pulse output frequency it is possible to determine the
flow rate of the liquid. The pulse frequency for maximum flow through the
unit (i.e. full scale flow) is detailed on the calibration certificate. This
differs from unit to unit. This output is approximately linear and scaleable
within the sensor’s range. For example:
For a flow range of 1.0-10.0l/min (Range 9) :
The calibration certificate gives the following:
At 10.0l/min the pulse output signal is 312Hz
At 5.0l/min the pulse output signal is 150Hz
At 2.0l/min the pulse output signal is 58Hz
If the output signal were 120Hz then the flow rate would be:
5.0 ÷ 150 × 120 = 4.0 l/min (using the closest calibration point)
c)
4-20mA Outputs
By monitoring the current output signal it is possible to determine the flow
rate of the liquid. 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 there is zero flow through 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 20-200ml/min (Range 4) :
At 200ml/min the output signal would be 20mA
If the output signal were 9mA then the flow rate would be:

Units With an Integral Display
The Model S-111, S-112 and S-114 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 6-9. 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 by using a cable assembly or power
adapter package (see above).

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.
101-M002, pg. 21 of 42
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.
5.
Zero Adjustments
It is impossible for there to be any zero drift so zero adjustments are
never required.
6.
Recalibration
The calibration of the FLO-SENSORS® or FLO-METERS® may be easily
verified using empirical methods.
It should be noted that the use of empirical methods outside a certified
calibration laboratory is subject to inaccuracy and error. These methods
should only be used to gain an indication of a sensor’s performance.
Please contact the McMillan Service Department if accurate, certified
recalibration is required.
A typical empirical calibration check may be carried out as follows:
Carefully adjust the flow rate so that the maximum output signal is
obtained. With the flow rate constant, liquid flowing through the unit
should be gathered in a container over a timed interval. The total volume
flowed over the timed period should then be measured using a measuring
cylinder. The actual flow rate (in the same units as the flow sensor
calibration certificate) may then be calculated. The actual maximum flow
rate should then be compared to the specified maximum flow rate to
determine the error in calibration. For example:
For a flow range of 20-200ml/min (Range 4) with a 0-5VDC
output:
With a constant flow and constant 5VDC output the actual volume
measured over 30 seconds was 102ml.
Therefore the actual flow rate is:
(102 / 30) x 60 = 204ml/min
The error is therefore 204 – 200 = 4ml/min or 2%
A second empirical check should be made at a flow rate below the
maximum for the unit e.g. at 50% of full scale. The calculated percentage
error at this flow should then be compared to the error at maximum flow.
If there is a big difference in the percentage errors then the flow signal is
no longer linear and the unit may be damaged (consult the McMillan
Service Department).
101-M002, pg. 22 of 42
Once it has been determined that the linearity is still acceptable and the
error in flow reading at maximum flow has been calculated, there are 3
options:
i.) Minor adjustments to actual calibration of the FLO-SENSOR® or FLOMETER® may be made by turning the gain potentiometer on the side of
the unit. For example:
For a unit with a flow range of 13-100ml/min (Range 3) and a
0-5VDC output:
With a constant flow and constant 5VDC output the actual volume
measured over 60 seconds was 103ml.
The correct voltage output for a flow of 103 ml/min is:
(5/100) x 103 = 5.15 V
With the flow at a constant 103 ml/min the gain potentiometer
should be carefully adjusted so that a voltage output reading of
5.15 V is obtained.
If the unit cannot be suitably adjusted please contact the McMillan Service
Department. Pulse outputs are not adjustable.
Adjusting the Gain Potentiometer Using a Flat Head Screwdriver
(Model 101 shown, other models similar)
ii.) Adjust the scaling endpoints in the display or data acquisition system.
For example:
101-M002, pg. 23 of 42
For a flow range of 50-500ml/min (Range 5) with a 0-5VDC
output:
With a constant flow and constant 5VDC output the actual volume
measured
over 60 seconds was 405ml.
Therefore the actual flow rate is:
(405 / 60) x 60 = 405ml/min
The display or data acquisition system may now to configured as
follows:
0 VDC = Zero flow
5VDC = 405ml/min
iii.) Apply the error factor to each flow reading taken. For example:
For a flow range of 0.2-2.0l/min (Range 7) connected to a display:
With a constant flow rate of 2.0 l/min on the display, the actual
volume measured over 20 seconds was 0.7l
Therefore the actual flow rate is:
(0.7 / 20) x 60 = 2.1 l/min
The error is therefore 2.1 – 2.0 = 0.1 l/min or 5%
If the display shows an uncorrected flow rate of 1.4 l/min then :
Corrected flow rate = Uncorrected flow rate + error = 1.4 + 5% =
1.47 l/min
7.
Calibrating FLO-SENSORS® or FLO-METERS® for Different Liquids
McMillan FLO-SENSORS® or FLO-METERS® will operate with most
translucent liquids subject to compatibility of the wetted parts. Best results
are obtained with low viscosity (less than 10 centistokes) liquids. For
information regarding higher viscosity liquids, contact the McMillan Service
Department.
Units are calibrated with deionized water as the reference media. Using
other liquids will effect the calibration. The amount of calibration error will
depend on the characteristics of the liquid being flowed.
The error in flow reading (or calibration) should be calculated and utilized
as detailed in section 6 above.

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.
Do not store a FLO-METER® or FLO-SENSOR® with any chemical other
than water (or air) inside it over an extended period of time. Prolonged
exposure to chemicals other than water may lead to precipitation or
corrosion.
2.
Cleaning and Flushing
If there is a build up of deposits or residues from the measured chemicals
it may be necessary to clean or flush the unit. This should be done by
flowing clean, particle free water 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.
Under no circumstances should gas or air be flowed through the unit. This
will cause severe damage.
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.
101-M002, pg. 25 of 42
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).

Troubleshooting Guide
Symptom
Possible Cause
Method of Correction
Unit Leaks
Fittings not tight enough.
Tighten fittings (see section
B4)
Sensor assembly cracked
Unit must be returned for
repair (see Section J)
Apply correct power
No output signal or
flow indication
Flow indication
“bounces” or
fluctuates
No power or low power
No flow passing through
unit
Display or output should
read zero if there is no flow.
Increase the flow rate until
a reading is obtained. (Do
not exceed the specified
maximum flow!)
Output shorted or
overloaded
Check electrical connections
(see section B5)
Improper connection
Check electrical connections
(see section B5) and ensure
connector is correctly
plugged in.
Moisture on internal
electronics
Allow unit to dry out in a
dry environment.
Output circuitry damaged
Unit must be returned for
repair (see Section J)
Liquid not translucent
enough.
Contact the McMillan
Service Department for
assistance.
Attempting to measure
flows below the specified
minimum for the unit
Use higher flow rates.
Flow is actually fluctuating
Correct flow source to
obtain steady flow
Not using the fittings
supplied by the
manuafacturer
Use the supplied fittings
Entrapped air or gas
Remove entrapped air (see
section C2)
Turbulence in tubing or
sensor
Straighten the inlet tubing
or lengthen it to at least 6”
(150mm)
Fluctuating input power
Correct the power source or
change to a regulated
supply
Mechanical sensor assembly
damaged
Unit must be returned for
repair (see Section J)

Symptom
Possible Cause
Method of Correction
Flow indication is not
linear and output too
low at lower flows
Attempting to measure
flows below the specified
minimum for the unit
Use higher flow rates
Liquid is too viscous
Best results are obtained
with liquids that have a
viscosity of 10cS or less.
Contact the McMillan
Service Department for
further information
Entrapped air or gas
Remove entrapped air (see
section C2)
Mechanical sensor assembly
damaged
Unit must be returned for
repair (see Section J)
Liquid has a different
viscosity and / or specific
gravity than water at 20°C
Calculate the flow reading
error / offset as explained in
section C6
Entrapped air or gas
Remove the entrapped air
(see section C2)
Mechanical sensor assembly
damaged
Unit must be returned for
repair (see Section J)
The maximum rated flow for
the unit is being exceeded.
Reduce the flow
Output circuits may be
damaged
Unit must be returned for
repair (see Section J)
Flow reading accuracy
is outside the
specification
Flow indication is fixed
at one value
