SPECIAL CONDITIONS FOR ATEX/IECEx SAFE USE
• The temperature class of the unit may be affected if the temperature of the measured fluid exceeds 55°C.
• The values of the flameproof joints are detailed in the drawings listed reference 99-7198.
• For model Ex d +ib requires a power supply of which the short circuit will not exceed 25A or the supply will have a fuse with
a breaking capacity of 1500A.
MOUNTING
CAUTION: When loosening a
compression fitting – beware of
the pressure in the pipe. The
probe may blow out of the pipe
causing injury and/or damage.

See Appendix A for recommended straight run and flow

Probe installation into a tee fitting
is not recommended
Recommended probe installation
Proper installation of the probe in the pipe or duct is essential for accurate air or gas flow measurement. Normal procedures for installing any type of flow element should be
followed.
A flow arrow is etched on the sides of the probe to designate flow direction. The instrument is calibrated with the
flow in this direction. Ensure that the flow arrow is aligned
in the direction of flow. The instrument is unable to recognize flow direction if inserted with the flow arrow in the
wrong direction.
It may be necessary to rotate the head of the instrument to
view the display while maintaining the proper flow orientation.
It is generally recommended that the sensor be located in
the center of the pipe. This location provides less sensitivity to changes in flow profile. Sensors mounted through
compression fittings have the ability to field adjust the sensor to the desired location.
Various methods of mounting the probe include compression fittings, threads, and flanged connections. Refer to
probe model numbers. The insertion probe can be installed
through a compression fitting. The use of a bored-through
fitting with 3⁄4" or 1" NPT connection for 3⁄4" outside diameter tube is recommended.
The use of Teflon® ferrules should be considered if repeated reposition of the sensor is considered. The stainless
steel ferrule can only be tightened once as it makes a permanent indentation on the probe. If using a compression fitting with stainless steel ferrules, ensure that the probe is in
the desired location before tightening.
The TA2 flow measurement is based on a fully developed
turbulent flow profile in a pipe with the specified inner diameter. Accuracy will be affected if these conditions are not
obtained. Installing the probe in a tee is not recommended
as the flow profile and the flow area are distorted.
For applications where it is desirable to install or remove
the probe without having to shut down the process,
Magnetrol’s Retractable Probe Assembly (RPA) can be utilized.
The TA2 with an insertion probe provides a point measurement and assumes that the velocity profile (see figures
below) is uniform over the entire width of the pipe or duct.
The user has the ability to compensate the flow measurements based upon flow profile considerations under the
Advanced Configuration section of the software.

NOTE: Do not install the probe in locations where condensed moisture can be present. The unit may cause a
false high flow indication. In some cases heat tracing or
insulation of the pipe must be considered to avoid
moisture condensation.
Install the TA2 sensor at a 45° angle to minimize moisture
drip. Use of different TA2’s as shown is recommended to
optimize the accuracy in a larger pipe dia.
Display
Connects to J1 on the logic board
CAUTION: Switch power off
when connecting/disconnecting
the display
The TA2 has a plug in display
(ordered with the unit or separately).
The display can be rotated in 90° increments.
Remove both mounting screws and reposition
at desired position.

WIRING
CAUTION: In harzardous area, do NOT power the unit until the cable gland is sealed and the housing
cover of the wiring compartment is screwed down securely / housing locking screw is fastened – disabling the removal of the cover.
NOTE: Wiring for Ex d and Ex d +i is identical. This means that for use in Zone 0 an Ex d device has to use Ex d cabling.

CONFIGURATION
IMPORTANT: TA2 units are pre-configured from factory (as per order specifications). Only modify configuration settings in case needed.
NOTE: When power is first applied to the TA2 there is an initialization period for the sensor to reach stabilization.
During this time the TA2 will output a 4 mA signal and the display (if provided) will read «Initializing TA2». Only after the
sensor has stabilized and a valid flow measurement is obtained will the display show a flow measurement, the output
signal will be active and the totalizer will begin counting.

Basic Configuration Menu
The Basic Configuration menu is used to select the display units and enter specific information for the application. Access this
section by pushing
when Basic Config is displayed from the Main Menu.
To calculate the flow or mass, it is necessary to accurately enter the inside area of the pipe or duct. If the pipe or duct is circular, simply enter the value of the inside diameter; the cross sectional area of the pipe is automatically calculated. If the duct is
rectangular, skip over the entry of diameter, and directly enter the cross sectional area in the area section. The instrument will
then back calculate an equivalent diameter.

Damping
Increasing the Damping will smooth the TA2 display and the loop output. This may be used in cases when turbulence is causing fluctuations in the measurement.
The damping value is expressed in time constants. A one-second time constant means that with a step change in flow, the
measured flow value will reach approximately 63 % of the new value in one second and approximately 99 % of the new value
in five seconds. The lower limit is 0 which means no damping (other than the inherent response time of the sensor); the upper
limit is 15 seconds.

* Installation factor: Changes in flow profile will affect the measurements of the TA2. Advanced users have the ability to adjust the
measurements for changes in flow profile using a polynomial relationship in the form of:
Corrected flow = A+Bv+Cv2
v = velocity in SFPM (Standard feet/min.). Contact Magnetrol for calculations to determine these factors.
The default is B = 1; and A and C = 0. To use the correction factor, develop a relationship between the flow measured by the TA2 and
the flow measured by a second flowmeter. Curve fit the second order polynomial (above) using the output of the TA2 and the output of
the second flowmeter for corrected flow. Then enter the appropriate values in the Advanced Configuration menu.

There are two separate menus for calibration parameters titled «Cal Parameters A» and «Cal Parameters B». These two different sets of calibration are used when the TA2 is calibrated on two gases or two different ranges. If the unit is calibrated for air,
then only «Cal Parameters A» is used. If calibrated for a different gas then the calibration parameters for the specified gas is
contained in «Cal Parameters A», the air calibration is contained in «Cal Parameters B».
«Cal Parameters A» and «Cal Parameters B» have an identical menu structure.

DIAGNOSTICS TEST
The TA2 has several diagnostics tests which may be routinely performed. When conducting these tests, the reported flow rate
will be zero.
Heater setting
The amount of current flowing to the heater is displayed
under Diagnostics/Heater Setting. This value can be verified by connecting a multi-meter across the Heater Bypass
terminals (J2. This board can be accessed by opening the
cover and removing the display module.
2
Zero power test
This test checks that the resistances of the RTDs have not
changed. The heater is turned off and the temperature difference between the two sensors is compared. The test
should be performed in a water bath (preferred) or under
flowing conditions. Conducting this test in still air will cause
the test to time out and provide inconclusive results.
Calibration verification procedure
The TA2 measures heat transfer. These procedures are
designed to permit the user to verify the calibration by
checking the heat transfer characteristics of the sensor. If
the heat transfer characteristics are approximately the
same when the test is conducted compared with when the
same data was collected at the factory during the initial calibration, the unit remains in calibration.
The procedure is performed under two different sets of conditions. Both tests should be conducted at “room temperature”; approximately +21 °C to +30 °C (+70 °F to +85 °F).
The test can be performed using the keypad and display,
HART®, or PACTware™ through the Diagnostics menu.
During the test, the display (or HART® or PACTware™) will
provide an indication of the measured temperature difference and if the Delta T measurement is stable.
Low Flow Validate—Simulates a low flow condition.
1.
2.
3.
Cover sensor tips to isolate from air currents. During
the test, the heater power is set and the Delta T (temperature difference) between the two RTDs is measured.
After completion of the test, the value of the temperature difference measured during the test is compared
against the previously stored value. (The original value
obtained when the units were initially calibrated can be
found on the original calibration certificate.)
1
The measured value should match the value shown on the
display. Any difference between the two values indicates
that the heater calibration is incorrect. If the heater circuit is
open, a nominal current value will be displayed, but the
measured current will be zero.

The temperature difference between the two sensors is displayed. Typical values will match within 0.15 °C.
Temperature difference may be as high as 0.5 °C depending upon test conditions. If greater than this value, contact
the factory as drift in the RTDs may have occurred.
High Flow Validate—Simulates a high flow condition.

3.
Support the TA2 vertically in a water bath. See picture
below. During the test, the heater power is set and the
Delta T (temperature difference) between the two
RTDs is measured.
After completion of the test, the value of the temperature difference measured during the test is compared
against the stored value. (The original value obtained
when the units were initially calibrated can be found on
the original calibration certificate.)
The value from the test should compare with the
stored (or original calibration value) within 1,5 °C. This
variation in part is due to potential variations of the
ambient temperature during the test and differences in
test methods.
If the temperature difference measured during the test is
greater than the recommended temperature difference indicated above in item “3”, then the overall accuracy of the
TA2 may be affected. Contact Magnetrol Technical support.
The value from the test should compare with the
stored (or original calibration value) within 1,5 °C. This
variation in part is due to potential variations of the
ambient temperature during the test and differences in
test methods.

Error messages
The TA2 Mass Flow Meter utilizes a 3-level hierarchy for
reporting diagnostics information: FAULTS, WARNINGS,
and INFORMATION. Faults and Warnings can be reviewed
on the rotating screen in the Home menu. These screens
capture only current conditions. Historic diagnostic information can be viewed in the HISTORY screen of the
Diagnostics Menu.
FAULT: The highest level in the hierarchy of diagnostics. A
Fault indicates a defect or failure in the circuitry or software,
or a calibration condition that makes reliable measurement
impossible. The mA value defaults to 3.6 mA, 22 mA, or
HOLD and a message is displayed on the rotating screen.
Further error information can be obtained by reviewing the
Diagnostic Menu screen.
38
WARNING: This is the second level in the hierarchy of
diagnostics. A Warning indicates conditions that are not
fatal but may affect the measurement. A message will
appear on the Home (rotating) screen when a Warning is
detected but will not affect the output current. Further error
information can be obtained by reviewing the Diagnostic
Menu screens.
INFORMATION: This is the lowest level in the hierarchy of
diagnostics. Information messages are for conditions that
provide operational factors that are not critical to the measurement. Further error information can be obtained by

Circuit board replacement
The input wiring board and display module can be replaced
without any effect on the performance and operation of the
TA2. The processor board contains the calibration information and is matched with the probe. If this circuit board is
replaced, re-entry of all the original calibration and configuration information is required. This information is contained
on the calibration certificate which can be supplied by
MAGNETROL. Use of PACTware™ is recommended for
re-entry of this data.
1. Make sure the power source is turned off.
2. The input wiring board is contained in the rear compartment where the input voltage wiring comes into. The
display module, power loop board and processor board
are contained in the front compartment.
3. Remove appropriate cover.

Replacement calibration
RTD calibration
If either the probe or the processor board is replaced in the
field, calibration of the RTDs in the probe will return the TA2
to like-new performance. NOTE: If this procedure is not followed, the accuracy will be affected; however, very repeatable flow measurements will be obtained.
Locate the sensor vertically in a water bath with an accurate temperature sensor directly adjacent to the probe tips.
It is preferable that the water is stirred during the calibration
to ensure the TA2 pins and temperature probe are at the
same temperature. Using the keypad and display, select
«Factory Config\Probe Params\Probe Temp Calib» and then
press the
key. The device will dynamically display the
To/Fo readings over a period of time. After 3 minutes, and
if the readings are stable enough, the display automatically changes to request entry of a password (126) followed
by the ambient water temperature. After the temperature is
entered, the device will display if the calibration is OK. The
device then automatically resets itself for normal operation.
A similar procedure exists for the DD and DTM.
Set point adjustment
A new set point must be calculated to complete the reconfiguration.
1. Place the probe in ambient temperature air where there
is no flow across the sensor. This can be accomplished
by wrapping the sensor tip with a piece of paper.
Flow recalibration
Calibration of the TA2 requires a flow bench or other
method for determining the flow rate. Using this procedure,
the user can re-calibrate the unit himself or use a local flow
calibration facility rather than returning the unit to the factory for recalibration. With an insertion probe, it is not necessary to calibrate in the same size pipe as the unit is
installed in. The TA2 has internal scale-up factors which
adjusts the data from the calibration pipe size to the installation pipe size.
Calibration requires the TA2 sensor to be positioned in a
test section; the test section should have a sufficient
upstream and downstream straight run to ensure the formation of a fully developed flow profile. Calibration should
be performed using the same gas which the unit is calibrated for. Optionally, an air equivalency calibration can be
performed. In this case, calibrate in air and contact the factory for air equivalency factors and equivalent air calibration rate.
Recalibration Procedure:
1. Select the set point; this is the temperature in degrees
Celsius which the TA2 maintains between the two sensors. If the unit is re-calibrated for the same application,
then it is probably not necessary to change the original
value. If it becomes necessary to change the set point
due to change in the calibration velocity or the type of
gas:
a. Record the set point under «Factory Config\Cal
Parameters (A or B)\Set Point».
b. Determine the maximum velocity in SFPM which the
unit will operate (SFPM equals the SCFM divided by
the flow area of the test section in square feet).
c. Install the probe in the test section and flow gas that
is equivalent to the maximum velocity in the calibration range.
d. Using the display, HART, or PACTware™, obtain the
signal value in mW from the Diagnostics menu.
e. Calculate a new set point using the formula:
New set point = old set point x (800/measured signal
(mW)). 800 mW is the desired maximum power rating
for the TA2.
f. Enter new set point in TA2 under «Factory
Configuration\Cal Parameters (A or B)\Set Point».
42
2. Go into «Diagnostics\Signal». Allow time for the signal to
stabilize to within ±1 mW and record the new signal.
3. Calculate a new set point by using the following formula:
New set point = set point x (zero flow signal ÷ new signal)
If replacing the probe, use the set point and zero flow
signal (ZFS) shown on the new calibration certificate
that came with the probe.
If replacing the processor board, use the set point and
ZFS on the original calibration certificate. If the original
calibration certificate is not available, contact Magnetrol
with the serial number of the unit found on the nameplate.
New signal is the value measured under step 2.
NOTE: If the TA2 is calibrated for a gas other than air,
there are two ZFS values on the certificate.
One is for air and the other is for the particular
gas. Use the ZFS for air when making the
adjustment in air.
4. Enter this new set point into the TA2 instead of the value
on the calibration certificate under «Factory Config\Cal
Parameters A\Set Point».
5. Return to the signal screen, similar to step 2, ensuring
there is no flow over the sensor. The signal value should
now agree with the original ZFS within 1 %. If desired,
steps 2 through 5 can be repeated.
2. Convert the flow rate in the application to the flow rate in
the test section using the formula:
Flow in test section = application flow x (flow area of
test section/flow area of application)
a. Allow a flow of a known amount of gas through the
test section, recording flow rate and TA2 signal (mW).
A minimum of 10 and a maximum of 30 data points
including a zero flow value should be obtained. One
data point should be taken at a flow rate approximately 20 % greater than the expected operating
range. The higher the number of data points, the better the overall accuracy of the instrument.
b. Convert the flow rate in the test section to mass
velocity in SFPM. Use Magnetrol STP conditions of
70 °F and 1 Atmosphere (14.69 psia).
c. Enter the Power and the corresponding Mass
Velocity into the TA2. This is easily performed using
PACTware™ but can also be entered directly into the
TA2 using the display and keypad or using HART.
These values should be entered in increasing order
to ensure a monotonically increasing curve.
Note password of 126 is required for entry of calibration data. (Contact Magnetrol if issues using this

d. After completion of entry of the calibration data,
check the display/HART®/PACTware™ for the number of points accepted (or table length). If this number
is less than the actual number of data points entered,
then there is an error in the entry of the calibration
data. Ensure that the data is entered so the curve is
monotonically increasing. The values of mass velocity and power should always be increasing over the
calibration range.
e. A Fault message will occur if there are fewer than 10
calibration data points in the calibration table.
3. Enter the flow area of the calibration test section. Units
of measurement are the same as selected under Basic
Config menu. This value is used in calculating the scaleup factor between the calibration test section and the
installation.
REPLACEMENT PARTS
NOTE: Replacement of the processor board / electronic module or the sensor requires entry of configuration data
from the Calibration Certificate.
CAUTION: EXPLOSION HAZARD
Do not disconnect equipment unless power has been switched off or the area is known to be
non-hazardous.

Portable display module
A portable display module for configuration and diagnosis of
multiple units is available (code 089-5219-002). This
portable module plugs into the electronics in the same manner as the normal display and uses the same software
menu. This module permits the user to reduce installation
cost by having one display module with keypad for multiple
TA2 units.
Usage of the display module requires that the housing cover
be removed during use and thus may not be useable in hazardous areas. In these cases, the HART® option should be
utilised.

APPENDIX A
The flow measurement of the TA2 assumes that the end
of the probe is 25 mm (1”) past the centreline and the
presence of a fully developed flow profile. See figure A.
As gas flows in a pipe or duct, the flow profile will change
with obstructions and changes in flow direction. As the
gas flows around an elbow, the momentum causes the
gas velocity on the outside of the elbow to increase and
the velocity on the inside to decrease. See figure B.
RD = 3,000,000
RD = 4,000

Figure C indicates the minimum recommended straight run distances required to obtain the desired fully developed flow
profile. If these straight-run distances are not available, the overall accuracy of the flow measurement will be affected;
however, the repeatability of the measurement will be maintained.
The user has the ability to enter correction factors to compensate for non-ideal flow profile conditions.

APPENDIX A
Conditioning plates
Flow conditioning plates may be provided in applications
where limited straight run is available. Plates are available
in flow body type sensor designs (TFT) from 1.5" to 4"
pipes. Plates may be purchased separately for pipe sizes
4" to 12" when using insertion probes (TXR).
The plate should be installed 2-5 diameters downstream of
the nearest obstruction, change in pipe inside diameter or
change in flow direction. For TXR designs, the insertion
probe can be installed 8 pipe diameters downstream of the
plate with 5 diameters required downstream of the TXR.
For TFT designs with the plate at the entrance, the downstream is provided in the length of the TFT.
Plates are to be fitted with gaskets (customer supplied) in
between flanges. If plates are not included and recommended straight run is not adhered to, the TA2 will provide
repeatable measurement and the installation factors can
be utilized.

APPENDIX B
TA2 Mass Flow Meter – Using both Pulse and 2nd mA connections
as compared to an active connection where the TA2 provides power for the output signal (sometimes referred to as
self-powered).
The pulse output and second mA output (commonly used
for temperature) in the TA2 share a common ground. They
are isolated from the remaining input and output connections of the instrument.
Isolation problems may be encountered if the user wants to
connect both the passive pulse output and the second mA
output (always passive connection) from the TA2 to a flow
computer or other input device with common grounds.
The attached illustration shows a recommended solution
using a solid state relay between the flow computer and the
active TA2 pulse output.
A flow computer or other receiving device may have common ground for the various input signals. This may cause
difficulties when using both the TA2 pulse and second mA
output with an external power supply or the power supply
in the flow computer. Magnetrol refers to the use of a separate power supply as a passive connection from the TA2

APPENDIX C
Enhanced TA2 Pulse Output
The Enhanced TA2 has an option for providing a pulse output. The Pulse is an open collector output; the output can
be either a powered (active) connection or a passive connection using an external power supply. With an active output the voltage will go from 0 to 24 VDC (± 10%) with each
pulse. The voltage on the passive connection will depend
on the power supply used.
1 second
One pulse will correspond to a specific amount of flow.
There are several factors which need to be configured to
obtain the desired operation.
Multiplier: The multiplier value is a factor which relates the
amount of flow per pulse. For instance a factor of 0.01 with
units set to Nm3 means that each pulse will correspond to
0.01 Nm3 or conversely there will be 100 pulses for every
Nm3.
Frequency: Represents the maximum frequency of the
pulses. This is selectable from 10 to 10,000 Hz. This value
should not exceed the maximum input rate of the device
receiving the pulses. If the actual pulse output based on the
flow measurement exceeds the maximum frequency
selected a Warning Message indicating “Pulse Multiplier
error” will appear on the display and be communicated over
HART. The pulse width is fixed based on the value selected. For instance with a selected maximum frequency of
1,000 each pulse occur every 1/1000 seconds (1 ms). Each
pulse is a square wave with a 50% duty cycle; half of each
pulse width is on with voltage applied and half off with no
voltage. This results in a pulse width of 0.0005 seconds
(0.5 ms). The pulses are transmitted at a fixed rate for a
fraction of a second with no pulses for the remaining time.
When configuring the frequency, calculate the pulse rate by
using a Time Factor which is equivalent to the number of
seconds in the time period. If flow rate is in units/minute the
Time Factor = 60; if the flow rate is in units/hour the Time
Factor = 3600.
The formula for determining the pulse rate is:
Pulse rate = Flow rate/(Time Factor * multiplier)
Example:
Flow rate = 200 Nm3/h
Time factor = 3600
Multiplier = 0.0001 (0.0001 Nm3/h/pulse)
The frequency will be equal to 200/(3600 * 0.0001) = 555 Hz and the maximum frequency can be set to either 1000 or 10.000.
