KNOWN.
4) Record the value calculated and displayed as Transducer Spacing.
Q2 PIPE PREPARATION AND TRANSDUCER
MOUNTING
NOTE: The following steps require information supplied by
the TFXL meter itself so it will be necessary to supply power
to the unit, at least temporarily, and connect to a computer
using ULTRALINK to obtain setup information.
Q1 TRANSDUCER LOCATION
1) In general, select a mounting location on the piping
system with a minimum of 10 pipe diameters (10 × the
pipe inside diameter) of straight pipe upstream and 5
straight diameters downstream. See Table 2.1 for addi-
tional con gurations.
2) If the application requires DTTN or DTTH transducers
select a mounting method for the transducers based on
pipe size and liquid characteristics. See Table 2.2. Trans-
ducer con gurations are illustrated in Figure Q.1 below.
NOTE: All DTTS and DTTC transducers use V-Mount
con guration.
3) Enter the following data into the TFXL transmitter via
the ULTRALINK™ software utility:
1. Transducer mounting method
2. Pipe O.D. (Outside Diameter)
3. Pipe wall thickness
4. Pipe material
5. Pipe sound speed*
6. Pipe relative roughness*
7. Pipe liner thickness
8. Pipe liner material
9. Fluid type
10. Fluid sound speed*
11. Fluid viscosity*
12. Fluid speci c gravity*
INTEGRAL & REMOTE DTTS AND DTTC
TRANSDUCERS
1) Refer to the signal strength values available on the Data
Display screen in the ULTRALINK software utility.
2) The pipe surface, where the transducers are to be
mounted, must be clean and dry. Remove scale, rust or
loose paint to ensure satisfactory acoustic conduction.
Wire brushing the rough surfaces of pipes to smooth
bare metal may also be useful. Plastic pipes do not
require preparation other than cleaning.
On horizontal pipe, choose a ow meter mounting
location within approximately 45-degrees of the side of
the pipe. See Figure Q.2. Locate the ow meter so that
the pipe will be completely full of liquid when ow is
occurring in the pipe. Avoid mounting on vertical pipes
where the ow is moving in a downward direction.
3) Apply a single ½” (12 mm) bead of acoustic couplant
grease to the top half of the transducer and secure it to
the pipe with bottom half or U-bolts.
4) Tighten the nuts so that the acoustic coupling grease
begins to ow out from the edges of the transducer
and from the gap between the transducer and the pipe.
Finger tighten only. Do not over tighten.
DTTN AND DTTH TRANSDUCERS
1) Place the ow meter in signal strength measuring
mode. This value is available in the data display of the
software utility.
2) The pipe surface, where the transducers are to be
mounted, must be clean and dry. Remove scale, rust or

the sound crosses the pipe once. The selection of how
transducers are mounted on opposite sides of the pipe and
method is based on pipe and liquid characteristics which
both have an e ect on how much signal is generated. The
ow meter operates by alternately transmitting and receiving
a frequency modulated burst of sound energy between the
two transducers and measuring the time interval that it takes
for sound to travel between the two transducers. The di erence in the time interval measured is directly related to the
velocity of the liquid in the pipe.

INTRODUCTION
GENERAL
The TFXL ultrasonic ow meter is designed to measure
the uid velocity of liquid within a closed conduit. The
transducers are a non-contacting, clamp-on type or clamparound, which will provide bene ts of non-fouling operation
and ease of installation.
APPLICATION VERSATILITY
The TFXL ow meter can be successfully applied on a wide
range of metering applications. The simple-to-program transmitter allows the standard product to be used on pipe sizes
ranging from ½ inch to 100 inches (12 mm to 2540 mm). A
variety of liquid applications can be accommodated:
ultrapure liquids sewage cooling water
potable water reclaimed water river water
chemicals plant e uent others
Because the transducers are non-contacting and have no
moving parts, the ow meter is not a ected by system pressure, fouling or wear.
The DTTN transducer set is rated to a pipe surface temperature of 250° F (121° C). High temperature DTTH transducers
can operate to a pipe surface temperature of 350° F (177° C).
The DTTS series of small pipe transducers can be used to a
pipe surface temperature of 185° F (85° C) and the DTTC high
temperature small pipe transducers are rated for 250° F
(121° C).
The TFXL uses a low voltage DC power source that provides
electrical safety for the user. Removing the cover allows access to all the meter connections and the computer interface
connection.
Non-volatile ash memory retains all user-entered con guration values in memory inde nitely, even if power is lost or
turned o .
The TFXL family of transit time ow meters utilize two
transducers that function as both ultrasonic transmitters
and receivers. The transducers are clamped on the outside
of a closed pipe at a speci c distance from each other. The
transducers can be mounted in V-Mount where the sound
transverses the pipe two times, W-Mount where the sound
transverses the pipe four times, or in Z-Mount where the
The enclosure should be mounted in an area that is convenient for servicing, calibration or for observation of the LCD
readout.
Mount the TFXL transmitter in a location that is:
~ Where little vibration exists.

Locate the transmitter within the length of transducer cable
that was supplied with the TFXL system. If this is not possible,
it is recommended that the cable be exchanged for one that
is of proper length. Both transducer cables must be of the
same length.
NOTE: The transducer cable carries low level, high frequency
signals. In general, it is not recommended to add additional
cable to the cable supplied with the DTTN, DTTH, DTTS or
DTTC transducers. If additional cable is required, contact the
factory to arrange an exchange for a transducer with the
appropriate length of cable. Cables to 990 feet (300 meters)
are available. To add cable length to a transducer, the cable
must be the same type as utilized on the transducer. Twinaxial
cables can be lengthened with like cable to a maximum
overall length of 100 feet (30 meters). Coaxial cables can be
lengthened with RG59 75 Ohm cable and BNC connectors to
990 feet (300 meters).
If the transmitter will be subjected to a wet environment, it is
recommended that the cover remain closed after con guration is completed. The faceplate of the TFXL is watertight, but
avoid letting water collect on it. A sealed cord grip or NEMA
4 conduit connection should be used where cables enter the
enclosure. Holes not used for cable entry should be sealed
with plugs.
To access terminal strips for electronic connectors, loosen
the four screws in the display lid and remove the cover. The
terminals where the transducers connect are located underneath the display. To connect transducers, remove the four
screws that secure the display and carefully move it out of
the way. Do not over stress the ribbon cable located between
the display and the microprocessor circuit boards.

of proper length. To add cable length to a transducer,
the cable must be the same type as utilized on the
transducer. Twinaxial cables can be lengthened with
like cable to a maximum overall length of 100 feet (30
meters). Coaxial cables can be lengthened with RG59
75 Ohm cable and BNC connectors to 990 feet (300
meters).
2) Mount the TFXL transmitter in a location:
~ Where little vibration exists.
~ That is protected from corrosive uids.
~ That is within the transmitters ambient temperature
limits -40 to +185° F (-40 to +85° C).
~ That is out of direct sunlight. Direct sunlight may
increase transmitter temperature to above the
maximum limit.
3) Mounting - Refer to Figure 1.2 for enclosure and
mounting dimension details. Ensure that enough room
is available to allow for door swing, maintenance and
conduit entrances. Secure the enclosure to a at surface
with two appropriate fasteners.
4) Conduit Holes - Conduit holes should be used where
cables enter the enclosure. Holes not used for cable
entry should be sealed with plugs.
NOTE: Use NEMA 4 [IP-65] rated ttings/plugs to maintain the
watertight integrity of the enclosure. Generally, the right side
conduit hole (viewed from front) is used for power, the bottom
conduit hole(s) for transducer connections.

Wiring methods and practices are to be made in accordance
with the NEC - National Electrical Code® - and/or other local
ordinances that may be in e ect. Consult the local electrical
inspector for information regarding wiring regulations.
When making connections to the eld wiring terminals
inside the ow meter, strip back the wire insulation approximately 0.25 inch (6 mm). Stripping back too little may cause
the terminals to clamp on the insulation and not make good
contact. Stripping back too much insulation may lead to a
situation where the wires could short together between adjacent terminals. Wires should be secured in the eld wiring
terminals using a screw torque of between 0.5 and 0.6 Nm.
If the DC ground terminal is to be utilized as a protective conductor terminal, the protective conductor shall be
applied rst and secured independently of other connections. The protective conductor shall be connected in
such a way that it is unlikely to be removed by servicing
not involving the protective conductor or there shall be a
warning marking requiring the replacement of the protective
conductor after removal.
Power the TFXL ow meter with a Class 2 direct current
(DC) power source. The power source should be capable of
supplying between 11 and 28 VDC at a minimum of 250 milliamps. With the power from the DC power source disabled or
disconnected, connect the positive supply wire and ground
to the appropriate eld wiring terminals in the ow meter.
See Figure 1.5. A wiring diagram decal is located on the inner
cover of the ow meter enclosure for reference.
IMPORTANT NOTE:
Not following instructions properly may impair
safety of equipment and/or personnel.
IMPORTANT NOTE:

FIGURE 1.3 TRANSDUCER CONNECTIONS
To access terminal strips for wiring, rst loosen the four
screws holding the top of the case to the bottom.
NOTE: The four screws are “captive” screws and cannot be
removed from the top of the case.
If the unit has a display remove the four Phillips head screws
that hold the display to the main circuit board and carefully
move it out of the way. Do not over stress the ribbon cable
located between the display and the microprocessor circuit
boards.
Guide the transducer terminations through the transmitter

Secure the transducer cable with the supplied conduit nut (if
exible conduit was ordered with the transducer).
NOTE: TFXL models with integral transducers have the transducers connected at the factory and the transducer connections
section can be skipped.
The terminals within TFXL are of a screw-down barrier
terminal type. Depending on the type of transducers being
used there are two terminal strip arrangements possible.
Remote mount small pipe transducers are connected to the
terminals found on the main circuit board.
IMPORTANT NOTE:
Do not connect the interface cable between a

Remote mount transducers are connected to a “daughter”
board found on the left hand side of the meter.
Connect the appropriate wires at the corresponding screw
terminals in the transmitter. Observe upstream and downstream orientation and wire polarity. See Figure 1.3.
NOTE: High temperature transducer cables come with red and
black wire colors. For the red and black combination, the red
wire is positive (+) and the black wire is negative (-).
NOTE: The transducer cable carries low level, high frequency
signals. In general, it is not recommended to add additional
length to the cable supplied with the transducers. If additional
cable is required, contact the factory to arrange an exchange
for a transducer with the appropriate length of cable. Cables
100 to 990 feet (30 to 300 meters) are available with RG59 75
Ohm coaxial cable. If additional cable is added, ensure that it is
the same type as utilized on the transducer. Twinaxial (blue and
white conductor) cables can be lengthened with like cable to
a maximum overall length of 100 feet (30 meters). Coaxial
cables can be lengthened with RG59 75 Ohm cable and BNC
connectors to 990 feet (300 meters).
DC POWER CONNECTIONS
The TFXL should be operated from an 11 to 28 VDC Class 2
power source capable of supplying a minimum of 250 mA
of current.
PART 2 TRANSDUCER
INSTALLATION
GENERAL
The transducers that are utilized by the TFXL contain piezoelectric crystals for transmitting and receiving ultrasonic
signals through walls of liquid piping systems. DTTN and
DTTH transducers are relatively simple and straightforward
to install, but spacing and alignment of the transducers is
critical to the system’s accuracy and performance. Extra care
should be taken to ensure that these instructions are carefully executed. DTTS and DTTC, small pipe transducers, have
integrated transmitter and receiver elements that eliminate
the requirement for spacing measurement and alignment.
Mounting of the DTTN and DTTH clamp-on ultrasonic transit
time transducers is comprised of three steps:
Connect power to the screw terminal block in the TFXL transmitter. See Figure 1.4. Utilize the conduit hole on the right
side of the enclosure for this purpose. Use wiring practices
that conform to local and national codes (e.g., The National
Electrical Code® Handbook in the U.S.)
Connect the DC power to 11 to 28 VDC In, and DC Gnd., as
in Figure 1.4.

a) A switch or circuit breaker is required in the
installation.
b) The switch or circuit breaker must be in close
proximity of the TFXL and within easy reach of
the operator.
c) The switch or circuit breaker must be marked as
the disconnect device for the TFXL.
1) Selection of the optimum location on a piping system.
2) Entering the pipe and liquid parameters into the software utility. The software utility will calculate proper
transducer spacing based on these entries.
3) Pipe preparation and transducer mounting.
STEP 1 MOUNTING LOCATION
The rst step in the installation process is the selection of an
optimum location for the ow measurement to be made. For
this to be done e ectively, a basic knowledge of the piping
system and its plumbing are required.
An optimum location is de ned as:
~ A piping system that is completely full of liquid when
measurements are being taken. The pipe may become
completely empty during a process cycle – which will
result in the error code 0010 (Low Signal Strength)
being displayed on the ow meter while the pipe is
empty. This error code will clear automatically once the
pipe re lls with liquid. It is not recommended to mount
the transducers in an area where the pipe may become
partially lled. Partially lled pipes will cause erroneous
and unpredictable operation of the meter.
~ A piping system that contains lengths of straight pipe
such as those described in Table 2.1. The optimum
straight pipe diameter recommendations apply to pipes
in both horizontal and vertical orientation. The straight
runs in Table 2.1 apply to liquid velocities that are
nominally 7 FPS (2.2 MPS). As liquid velocity increases
above this nominal rate, the requirement for straight
pipe increases proportionally.

The ow meter system will provide repeatable measurements on piping systems that do not meet these requirements, but accuracy of these readings may be in uenced to
various degrees.
STEP 2 TRANSDUCER SPACING
TFXL remote mount transit time ow meters can be used
with four di erent transducer types: DTTN, DTTH, DTTS
and DTTC. Meters that utilize the DTTN or DTTH transducer
sets consist of two separate sensors that function as both
ultrasonic transmitters and receivers. DTTS and DTTC transducers integrate both the transmitter and receiver into one
assembly that xes the separation of the piezoelectric crystals. DTTN and DTTH transducers are clamped on the outside
of a closed pipe at a speci c distance from each other.

The DTTN and DTTH transducers can be mounted in:
W-Mount where the sound traverses the pipe four
times. This mounting method produces the best relative
travel time values but the weakest signal strength.
V-Mount where the sound traverses the pipe twice.
V-Mount is a compromise between travel time and
signal strength.
Z-Mount where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe
once. Z-Mount will yield the best signal strength but
the smallest relative travel time.
For further details, reference Figure 2.1. The appropriate
mounting con guration is based on pipe and liquid characteristics. Selection of the proper transducer mounting
method is not entirely predictable and many times is an

exactly what the TFXL calculates, so the calculated spacing
should be used if signal strength is satisfactory. If the pipe
is not round, the wall thickness not correct or the actual
liquid being measured has a di erent sound speed than the
liquid programmed into the transmitter, the spacing can vary
from the calculated value. If that is the case, the transducers
should be placed at the highest signal level observed by
moving the transducers slowly around the mount area.
Before the transducers are mounted onto the pipe surface,
an area slightly larger than the at surface of each transducer
must be cleaned of all rust, scale and moisture. For pipes with
rough surfaces, such as ductile iron pipe, it is recommended
that the pipe surface be wire brushed to a shiny nish. Paint
and other coatings, if not aked or bubbled, need not be
removed. Plastic pipes typically do not require surface preparation other than soap and water cleaning.
NOTE: Transducer spacing is calculated on “ideal” pipe.
Ideal pipe is almost never found so the transducer spacing

the transducers should be mounted 180 radial degrees from
one another and at least 45 degrees from the top-deadcenter and bottom-dead-center of the pipe. See Figure 2.2.

1) Place the upstream transducer in position and secure

Verify that the transducer is true to the pipe and adjust
as necessary. Tighten the transducer strap securely.
2) Place the downstream transducer on the pipe at the
calculated transducer spacing. See Figure 2.5. Apply
rm hand pressure. If signal strength is greater than
5, secure the transducer at this location. If the signal
strength is not 5 or greater, using rm hand pressure

APPLICATION OF COUPLANT
For DTTN and DTTH transducers, place a single bead of
couplant, approximately ½ inch (12 mm) thick, on the at
face of the transducer. See Figure 2.4. Generally, a siliconebased grease is used as an acoustic couplant, but any greaselike substance that is rated not to “ ow” at the temperature
that the pipe may operate at will be acceptable. For pipe
surface temperature over 150° F (65° C), acoustic couplant
(P.N. D002-2011-011) is recommended.
06-TTM-UM-00158 8/2012 13
Signal strength is displayed on the main data screen in
the software utility. See Part 4 of this manual for details
regarding the software utility. Clamp the transducer
at the position where the highest signal strength is
observed. The factory default signal strength cuto
setting is 5, however there are many application speci c
conditions that may prevent the signal strength from
attaining this level. For the TFXL, signal levels much
less than 5 will probably not be acceptable for reliable
readings.
3) If after adjustment of the transducers the signal
strength does not rise to above 5, then an alternate
transducer mounting method should be selected. If the
mounting method was W-Mount, then re-con gure the
transmitter for V-Mount, move the downstream transducer to the new spacing distance and repeat Step 4.
NOTE: Mounting of high temperature transducers is similar to

the temperature that will be present on the pipe surface.
DTTS/DTTC SMALL PIPE TRANSDUCER AND
INTEGRAL MOUNT INSTALLATION
The small pipe transducers are designed for speci c pipe
outside diameters. Do not attempt to mount a DTTS/DTTC or
integral mount transducer onto a pipe that is either too large
or too small for the transducer. Contact the manufacturer to
arrange for a replacement transducer that is the correct size.
DTTS/DTTC and integral installation consists of the
following steps:
1) Apply a thin coating of acoustic coupling grease to both
halves of the transducer housing where the housing
will contact the pipe. See Figure 2.6.
2) On horizontal pipes, mount the transducer in an orientation such that the cable exits at ±45 degrees from the
side of the pipe. Do not mount with the cable exiting on
either the top or bottom of the pipe. On vertical pipes
the orientation does not matter. See Figure 2.2.
3) Tighten the wing nuts or “U” bolts so that the acoustic
coupling grease begins to ow out from the edges of
the transducer or from the gap between the transducer
halves. Do not over tighten.
4) If signal strength is less than 5, remount the transducer
at another location on the piping system.

CONFIGURATION
Installation on larger pipes requires careful measurements
of the linear and radial placement of the DTTN and DTTH
transducers. Failure to properly orient and place the transducers on the pipe may lead to weak signal strength and/or
inaccurate readings. This section details a method for properly locating the transducers on larger pipes. This method
requires a roll of paper such as freezer paper or wrapping
paper, masking tape and a marking device.
1) Wrap the paper around the pipe in the manner shown
in Figure 2.11. Align the paper ends to within ¼ inch
(6 mm).
2) Mark the intersection of the two ends of the paper to
indicate the circumference. Remove the template and
spread it out on a at surface. Fold the template in half,
bisecting the circumference. See Figure 2.12.

4) The two marks on the pipe are now properly aligned
and measured. If access to the bottom of the pipe
prohibits the wrapping of the paper around the circumference, cut a piece of paper ½ the circumference of the
pipe and lay it over the top of the pipe. The length of ½
the circumference can be found by:
½ Circumference = Pipe O.D. × 1.57
The transducer spacing is the same as found in the
Transducer Positioning section. Mark opposite corners
of the paper on the pipe. Apply transducers to these
two marks.
5) For DTTN and DTTH transducers, place a single bead of
couplant, approximately ½ inch (12 mm) thick, on the
at face of the transducer. See Figure 2.4. Generally, a
silicone-based grease is used as an acoustic couplant,
but any good quality grease-like substance that is rated
to not “ ow” at the temperature that the pipe may
operate at will be acceptable.

6) Place the upstream transducer in position and secure
with a stainless steel strap or other fastening device.
Straps should be placed in the arched groove on the
end of the transducer. A screw is provided to help hold
3) Crease the paper at the fold line. Mark the crease. Place
a mark on the pipe where one of the transducers will
be located. See Figure 2.2 for acceptable radial orientations. Wrap the template back around the pipe, placing
the beginning of the paper and one corner in the loca-
the transducer onto the strap. Verify that the transducer
is true to the pipe, adjust as necessary. Tighten transducer strap securely. Larger pipes may require more
than one strap to reach the circumference of the pipe.
7) Place the downstream transducer on the pipe at the
06-TTM-UM-00158 8/2012 15
calculated transducer spacing. See Figure 2.13. Using
rm hand pressure, slowly move the transducer both
towards and away from the upstream transducer while
observing signal strength. Clamp the transducer at the
position where the highest signal strength is observed.
Signal strength of between 5 and 98 is acceptable. The
factory default signal strength setting is 5, however
there are many application speci c conditions that may
prevent the signal strength from attaining this level.
A minimum signal strength of 5 is acceptable as long as
this signal level is maintained under all ow conditions.
On certain pipes, a slight twist to the transducer may
cause signal strength to rise to acceptable levels.
8) Certain pipe and liquid characteristics may cause signal
strength to rise to greater than 98. The problem with
ating a TFXL with very high signal strength is
oper
that the signals may saturate the input ampli ers
and cause erratic readings. Strategies for lowering
signal strength would be changing the transducer
mounting method to the next longest transmission path. For example, if there is excessive signal
strength and the transducers are mounted in a
Z-Mount, try changing to V-Mount or W-Mount.
Finally you can also move one transducer slightly
o line with the other transducer to lower signal
strength.
9)
Secure the transducer with a stainless steel strap
or other fastener.

3) Slide the two transducer clamp brackets towards the

the notch in the clamp aligns with zero on the scale. See

pressure so that the couplant lls the gap between the
pipe and transducer.)

rails near the dimension derived in the transducer

The TFXL is also available with a totalizing pulse output.
420 mA OUTPUT
The 4-20 mA output interfaces with most recording and
logging systems by transmitting an analog current signal
that is proportional to system ow rate. The 4-20 mA output
is internally powered (current sourcing) and can span negative to positive ow/energy rates.

BATCH/TOTALIZER OUTPUT FOR TFXL
Totalizer mode con gures the output to send a 33 mSec
pulse each time the display totalizer increments divided by
the TOT MULT. The TOT MULT value must be a whole, posi-
tive, numerical value.
For example, if the totalizer exponent (TOTL E) is set to E0
(×1) and the totalizer multiplier (TOT MULT) is set to 1, then
the output will pulse each time the totalizer increments one
count, or each single, whole measurement unit totalized.
If the totalizer exponent (TOTL E) is set to E2 (×100) and the
totalizer multiplier (TOT MULT) is set to 1, then the control
output will pulse each time the display totalizer increments
or once per 100 measurement units totalized.
If the totalizer exponent (TOTL E) is set to E0 (×1) and
the totalizer multiplier (TOT MULT) is set to 2, the control
output will pulse once for every two counts that the totalizer
increments.

The frequency output is a TTL circuit that outputs a pulse
waveform that varies proportionally with ow rate. This type
of frequency output is also know as a “Rate Pulse” output. The
output spans from 0 Hz, normally at zero ow rate to 1,000
Hz at full ow rate (con guration of the MAX RATE parameter is described in detail in the ow meter con guration
section of this manual).

The frequency output is proportional to the maximum ow
rate entered into the meter. The maximum output frequency
is 1,000 Hz.
If, for example, the MAX RATE parameter was set to 400 GPM
then an output frequency of 500 Hz (half of the full scale
frequency of 1,000 Hz) would represent 200 GPM.
TOTALIZER OUTPUT OPTION FOR TFXL
TFXL units can be ordered with a totalizer pulse output option. This option is installed in the position where the rate
pulse would normally be installed.
In addition to the control outputs, the frequency output can
be used to provide total information by use of a “K-factor”.
A K-factor simply relates the number of pulses from the
frequency output to the number of accumulated pulses that
equates to a speci c volume.
06-TTM-UM-00158 8/2012 17
For the TFXL this relationship is described by the following
equation. The 60,000 relates to measurement units in

would require a di erent numerator.

PART 4 ULTRALINK UTILITY
INTRODUCTION
The ULTRALINK utility is used for con guring, calibrating
and communicating with the TFXL family of ow meters.
Additionally, it has numerous troubleshooting tools to make
diagnosing and correcting installation problems easier.
A practical example would be if the MAX RATE for the appli-
cation were 400 GPM, the K-factor (representing the number
of pulses accumulated needed to equal 1 Gallon) would be:
K factor Pulses Per Gallon
60,000
400
GPM
150
If the frequency output is to be used as a totalizing output,
the TFXL and the receiving instrument must have identical
K-factor values programmed into them to ensure that accurate readings are being recorded by the receiving instrument.
Unlike standard mechanical ow meters such as turbines,
gear or nutating disk meters, the K-factor can be changed by
modifying the MAX RATE ow rate value.
NOTE: For a full treatment of K-factors please see the
Appendix of this manual.
There are two frequency output types available:
Turbine meter simulation - This option is utilized
when a receiving instrument is capable of interfacing
directly with a turbine ow meter’s magnetic pickup.
The output is a relatively low voltage AC signal whose
amplitude swings above and below the signal ground
reference. The minimum AC amplitude is approximately
500 mV peak-to-peak. To activate the turbine output
circuit, turn SW1 OFF.

TRANSDUCER
Transducer Typ e selects the transducer that will be
connected to the TFXL ow meter. Select the appropriate
transducer type from the drop-down list. This selection
in uences transducer spacing and ow meter performance,
so it must be correct. If you are unsure about the type of
transducer to which the TFXL will be connected, consult the
shipment packing list or call the manufacturer for assistance.
NOTE: A change of Transducer Type will cause a System
Con guration Error (1002: Sys Con g Changed) to occur. This

error will clear when the microprocessor is reset or power is
cycled on the ow meter.
Transducer Mount selects the orientation of the transducers
on the piping system. See Part 2 of this manual and Table
2.2 for detailed information regarding transducer mounting
modes for particular pipe and liquid characteristics. Whenever Transducer Mount is changed, a download command
and subsequent microprocessor reset or ow meter power
cycle must be conducted.
BASIC TAB
GENERAL
The general heading allows users to select the measurement
system for meter setup, either English or Metric and choose
from a number of pre-programmed small pipe con gurations in the Standard Con gurations drop-down. If pipe
measurements are to be entered in inches, select English. If
pipe measurements are to be entered in millimeters, select
Metric. If the General entries are altered from those at instrument start-up, then click on the Download button in the
lower right-hand portion of the screen and cycle power to
the TFXL.
When using the Standard Con gurations drop-down menu
alternate, menu choices can be made by using the following
guidelines:

Transducer Spacing is a value calculated by the TFXL
rmware that takes into account pipe, liquid, transducer
and mounting information. This spacing will adapt as these
parameters are modi ed. The spacing is given in inches
for English units selection and millimeters for Metric. This
value is the lineal distance that must be between the transducer alignment marks. Selection of the proper transducer
mounting method is not entirely predictable and many times
is an iterative process.
NOTE: This setting only applies to DTTN, and DTTH
transducers.
Transducer Flow Direction allows the change of the
direction the meter assumes is forward. When mounting
TFXL meters with integral transducers, this feature allows
upstream and downstream transducers to be “electronically”
reversed, making upside down mounting of the display
unnecessary.
Pipe Material is selected from the pull-down list. If the pipe

Min Flow is the minimum volumetric ow rate setting
entered to establish ltering parameters. Volumetric entries
will be in the Flow Rate Units. For unidirectional measurements, set Min Flow to zero. For bidirectional measurements,
set Min Flow to the highest negative (reverse) ow rate
expected in the piping system.
Max Flow is the maximum volumetric ow rate setting
entered to establish ltering parameters. Volumetric entries
FIGURE 4.4 FLOW TAB
will be in the Flow Rate Units. For unidirectional measurements, set Max Flow to the highest (positive) ow rate
expected in the piping system. For bidirectional measurements, set Max Flow to the highest (positive) ow rate
expected in the piping system.
Low Flow Cuto is provided to allow very low ow rates
(that can be present when pumps are o and valves are
closed) to be displayed as zero ow. Typical values that
should be entered are between 1.0% and 5.0% of the ow
range between Min Flow and Max Flow.
Low Signal Cuto is used to drive the ow meter and its
outputs to the value speci ed in the Substitute Flow eld
when conditions occur that cause low signal strength. A
signal strength indication below 5 is generally inadequate for
measuring ow reliably, so generally the minimum setting
for Low Signal Cuto is 5. A good practice is to set the Low
Signal Cuto at approximately 60-70% of actual measured
maximum signal strength.
NOTE: The factory default “Low Signal Cuto ” is 5.
If the measured signal strength is lower than the Low Signal
Cuto setting, a “Signal Strength too Low” highlighted in
red will become visible in the text area to the left in the Data
Display screen until the measured signal strength becomes
greater than the cuto value.
Signal strength indication below 2 is considered to be no
signal at all. Verify that the pipe is full of liquid, the pipe size
and liquid parameters are entered correctly, and that the
transducers have been mounted accurately. Highly aerated
liquids will also cause low signal strength conditions.
Substitute Flow is a value that the analog outputs and the
ow rate display will indicate when an error condition in the
ow meter occurs. The typical setting for this entry is a value
that will make the instrument display zero ow during an
error condition.
Substitute Flow is set as a percentage between Min Flow and
Max Flow. In a unidirectional system, this value is typically
set to zero to indicate zero ow while in an error condition.
In a bidirectional system, the percentage can be set such that
zero is displayed in an error condition. To calculate where

FILTERING TAB
The Filtering tab contains several lter settings for the TFXL
ow meter. These lters can be adjusted to match response
times and data “smoothing” performance to a particular
application.

Advanced Filter Settings:
File Open... File Save...
Output Security
Time Domain Filter:
Time Domain Filter (range 1-256) adjusts the number
of raw data sets (the wave forms viewed on the software
Diagnostics Screen) that are averaged together. Increasing
this value will provide greater damping of the data and slow
the response time of the ow meter. Conversely, lowering
this value will decrease the response time of the meter to
changes in ow/energy rate. This lter is not adaptive, it is
operational to the value set at all times.
NOTE: The TFXL completes a measurement in approximately
350-400 mS. The exact time is pipe size dependent.
Flow Filter (Damping) establishes a maximum adaptive
lter value. Under stable ow conditions ( ow that varies less
than the Flow Filter Hysteresis entry), this adaptive lter
will increase the number of successive ow readings that are
averaged together up to this maximum value. If ow changes
outside of the Flow Filter Hysteresis window, the lter
adapts by decreasing the number of averaged readings and
allows the meter to react faster.
The damping value is increased to increase stability of the
ow rate readings. Damping values are decreased to allow
the ow meter to react faster to changing ow rates. The
factory settings are suitable for most installations. Increasing
this value tends to provide smoother steady-state ow readings and outputs.

Entry of data in the Basic and Flow tabs is all that is required
to provide ow measurement functions to the ow meter.
If the user is not going to utilize input/output functions,
click on the Download button to transfer the con guration
to the TFXL instrument. When the con guration has been
completely downloaded, turn the power to the meter o and
then on again to guarantee the changes take e ect.
Flow Filter Hysteresis creates a window around the average
ow measurement reading allowing small variations in
ow without changing the damping value. If the ow varies
within that hysteresis window, greater display damping
will occur up to the maximum values set by the Flow Filter
(Damping) entry. The lter also establishes a ow rate
window where measurements outside of the window
06-TTM-UM-00158 8/2012 21
are examined by the Bad Data Rejection lter. The value is
entered as a percentage of actual ow rate.
For example, if the average ow rate is 100 GPM and the
Flow Filter Hysteresis is set to 5%, a lter window of 95-105
GPM is established. Successive ow measurements that are
measured within that window are recorded and averaged in
accordance with the Flow Filter Damping setting. Flow read-
ings outside of the window are held up in accordance with
the Bad Data Rejection lter.
Flow Filter MinHysteresis sets a minimum hysteresis
window that is invoked at sub 0.25 FPS (0.08 MPS) ow rates,
where the “of rate” Flow Filter Hysteresis is very small and
ine ective. This value is entered in pico-seconds (ρ sec) and
is di erential time. If very small uid velocities are to be
measured, increasing the Flow Filter MinHysteresis value
can increase reading stability.
Flow Filter Sensitivity allows con guration of how fast the
Flow Filter Damping will adapt in the positive direction.
Increasing this value allows greater damping to occur faster
than lower values. Adaptation in the negative direction is not
user adjustable.
Bad Data Rejection is a value related to the number of
successive readings that must be measured outside of
the Flow Filter Hysteresis or Flow Filter MinHysteresis
windows before the ow meter will use that ow value.
Larger values are entered into Bad Data Rejection when
measuring liquids that contain gas bubbles, as the gas
bubbles tend to disturb the ultrasonic signals and cause
more extraneous ow readings to occur. Larger Bad Data
Rejection values tend to make the ow meter more sluggish
to rapid changes in actual ow rate.
OUTPUT TAB
The entries made in the Output tab establish input and
output parameters for the ow meter. Select the appropriate
function from the pull-down menu and press the Download button. When a function is changed from the factory
setting, a Con guration error (1002) will result. This error
will be cleared by resetting the TFXL microprocessor from
the Communications/Commands/Reset Target button or
by cycling power on the TFXL ow meter. Once the proper
output is selected and the microprocessor is reset, calibration
and con guration of the modules can be completed.
FIGURE 4.6 OUTPUT TAB
CHANNEL 1 420 mA FREQUENCY
CONFIGURATION
NOTE: The 4-20 mA Output Frequency Menu applies to all
TFXL versions and is the only output choice for Channel 1.
The Channel 1 menu controls how the 4-20 mA output is
spanned for all TFXL models.
The Flow at 4 mA / 0 Hz and Flow at 20 mA / 1,000 Hz settings
are used to set the span for both the 4-20 mA output and the
0-1,000 Hz frequency output on the TFXL meter versions.
The 4-20 mA output is internally powered (current sourcing)
and can span negative to positive ow rates. This output
interfaces with virtually all recording and logging systems
by transmitting an analog current that is proportional to
system ow rate. Independent 4 mA and 20 mA span settings
are established in rmware using the ow measuring range
entries. These entries can be set anywhere in the - 40 to + 40
FPS (-12 to +12 MPS) range of the instrument. Resolution of
the output is 12-bits (4096 discrete points) and can drive up
to a 900 Ohm load. When powered by a DC supply, the load is
limited by the input voltage supplied to the instrument. See
Figure 3.1 for allowable loop loads.
Flow at 4 mA / 0 Hz
Flow at 20 mA / 1,000 Hz
The Flow at 4 mA / 0 Hz and Flow at 20 mA / 1,000 Hz entries
are used to set the span of the 4-20 mA analog output and
the frequency output on TFXL versions. These entries are
volumetric rate units that are equal to the volumetric units
con gured as rate units and rate interval discussed on
Page 23.
For example, to span the 4-20 mA output from -100 GPM to
+100 GPM with 12 mA being 0 GPM, set the Flow at 4 mA / 0
Hz and Flow at 20 mA / 1,000 Hz inputs as follows:
22 06-TTM-UM-00158 8/2012
Flow at 4 mA / 0 Hz = -100.0
Flow at 20 mA / 1,000 Hz = 100.0
Calibration (Page 1 of 3) - Zero Flow
If the meter were a TFXL, this setting would also set the span
for the frequency output. At -100 GPM, the output frequency
would be 0 Hz. At the maximum ow of 100 GPM, the output
frequency would be 1,000 Hz, and in this instance a ow of
zero would be represented by an output frequency of 500 Hz.
Example 2 - To span the 4-20 mA output from 0 GPM to +100
GPM with 12 mA being 50 GPM, set the Flow at 4 mA / 0 Hz
and Flow at 20 mA / 1,000 Hz inputs as follows:
Flow at 4 mA / 0 Hz = 0.0
Flow at 20 mA / 1,000 Hz = 100.0
For the TFXL meter, in this instance, zero ow would be
represented by 0 Hz and 4 mA. The full scale ow or 100 GPM
would be 1,000 Hz and 20 mA and a midrange ow of 50
GPM would be expressed as 500 Hz and 12 mA.
4-20 Test -- 4-20 mA Output Test (Value)
Allows a simulated ow value to be sent from the 4-20 mA
output. By incrementing this value, the 4-20 mA output will
transmit the indicated current value.

KFACTORS EXPLAINED
The K-factor (with regards to ow) is the number of pulses that must be accumulated to equal a particular volume of uid. You
can think of each pulse as representing a small fraction of the totalizing unit.
An example might be a K-factor of 1000 (pulses per gallon). This means that if you were counting pulses, when the count total
reached 1000, you would have accumulated 1 Gallon of liquid. Using the same reasoning each individual pulse represents an
accumulation of 1/1000 of a gallon. This relationship is independent of the time it takes to accumulate the counts.
The frequency aspect of K-factors is a little more confusing because it also involves the ow rate. The same K-factor number,
with a time frame added, can be converted into a ow rate. If you accumulated 1000 counts (one gallon) in one minute, then
your ow rate would be 1 GPM. The output frequency, in Hz, is found simply by dividing the number of counts (1000) by the
number of seconds (60) to get the output frequency.
1000 ÷ 60 = 16.6666... Hz. If you were looking at the pulse output on a frequency counter, an output frequency of 16.666...Hz
would be equal to 1 GPM. If the frequency counter registered 33.333...Hz (2 × 16.666...Hz), then the ow rate would be 2 GPM.
Finally, if the ow rate is 2 GPM, then the accumulation of 1000 counts would take place in 30 seconds because the ow rate,
and hence the speed that the 1000 counts is achieved, is twice as great.
Calculating K-factors for Ultrasonic meters
Many styles of ultrasonic ow meters are capable of measuring ow in a wide range of pipe sizes. Because the pipe size and
volumetric units the meter will be used on vary, it is not possible to provide a discrete K-factor. Instead the velocity range of
the meter is usually provided along with a maximum frequency output.
The most basic K-factor calculation requires that an accurate ow rate and the output frequency associated with that ow rate
be known.
Example 1:
Known values are:
Frequency = 700 Hz
Flow Rate = 48 GPM
1) 700 Hz × 60 sec = 42,000 pulses per min
2)
Example 2:
Known values are:
K factor pulses per gallon
Full Scale Flow Rate = 85 GPM
Full Scale Output Frequency = 650 Hz
1) 650 Hz x 60 sec = 39,000 pulses per min

458.82
The calculation is a little more complex if velocity is used because you rst must convert the velocity into a volumetric ow
rate to be able to compute a K-factor.
To convert a velocity into a volumetric ow, the velocity measurement and an accurate measurement of the inside diameter
of the pipe must be known. Also needed is the fact that 1 US gallon of liquid is equal to 231 cubic inches.
Example 3:
Known values are:
Velocity = 4.3 ft/sec
Inside Diameter of Pipe = 3.068 in
1) Find the area of the pipe cross section.

So for every foot of uid travel 0.384 gallons will pass.
What is the ow rate in GPM at 4.3 ft/sec?
0.384 gallons × 4.3 FPS × 60 sec (1 min) = 99.1 GPM
Now that the volumetric ow rate is known, all that is needed is an output frequency to determine the K-factor.
