BEFORE OPERATING THE TFXP
Important Notice!
The TFXP flow meter is equipped with a Lead Acid Gel
Cell battery. This battery will require charging before initial operation.
Apply power, utilizing the enclosed 12 Volt DC output line
power converter or cigarette-style power cord, to the
TFXP for a period of 16-24 hours prior to using the product for the first time. The power converter connects to the
socket connection located on the side of the enclosure.
See Figure 1.1. A fully charged battery will provide up to
24 hours of continuous operation before recharging will be
necessary.
Figure 1.1
When the battery level has decreased to a point where recharging is required, the LOW BATTERY indicator will illuminate on the front panel. At that point, the meter will only
operate a short time more until it automatically turns itself
off—preventing excessive battery discharge that can damage the Gel Cell battery. The TFXP has an integral charging circuit that prevents overcharging. The instrument can
be permanently connected to AC line power without damaging the flow meter or the battery. Page 1.10 of this
manual contains additional recommendations to preserve
and maximize the power in the TFXP battery.
If the TFXP is to be used for extended periods of operation, the AC power converter or the 12 volt cigarette converter can remain connected indefinitely.

TFXP
PART 1 - INTRODUCTION
General
The TFXP ultrasonic flow meter is designed to measure
the fluid velocity of liquid within closed conduit (pipe). The
transducers are a non-contacting, clamp-on type, which
will provide benefits of non-fouling operation and ease of
installation.
TFXP transit time flow 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
specific distance from
each other. The transducers can be mounted in V-mode
where the sound transverses the pipe two times, W-mode
where the sound transverses the pipe four times, or in Zmode where the transducers are mounted on opposite
sides of the pipe and the sound crosses the pipe once.
This selection is based on pipe and liquid characteristics.
The flowmeter 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 difference in the time interval measured is directly related to the velocity of the liquid in the pipe.
Application
Versatility
Rev. 4/01
The TFXP flow 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 1 - 100 inch [ 25 - 2540 mm ]
internal diameters. A variety of liquid applications can be
accommodated: ultrapure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river
water, plant effluent, etc. Because the transducers are
non-contacting and have no moving parts, the flow meter
is not affected by system pressure, fouling or wear. Standard transducers are rated to 300°F [150°C]. Higher temperatures can be accommodated. Please consult the Dynasonics factory for assistance.

Considerations
After unpacking, it is recommended to save the shipping
carton and packing materials in case the instrument is
stored or re-shipped. Inspect the equipment and carton
for damage. If there is evidence of shipping damage, notify the carrier immediately.
When the TFXP is to be utilized for extended periods of
time in one location, the enclosure should be placed in
an area that is convenient for servicing, calibration or for
observation of the LCD readout.
1. Locate the transmitter within the length of transducer
cable that was supplied with the TFXP system. If this
is not possible, do not attempt to add additional cable
to the transducer. Contact the Dynasonics factory to
coordinate an exchange for the proper cable length.
Transducer cables that are up to 990 feet [300 meters] are available.
2. Place the TFXP transmitter in a location that is:
♦ Where little vibration exists.
♦ Protected from falling corrosive fluids.
♦ Within ambient temperature limits -40 to 185°F [-40 to
85°C]
♦ Out of direct sunlight. Direct sunlight may increase
temperatures within the transmitter to above maximum limit.
3. If the transmitter will be subjected to a wet environment, it is recommended that the cover remain closed
and the latches secured after configuration is completed. The faceplate/keypad of the TFXP is watertight, but avoid letting water collect on the keypad
area.

Electrical
Connections
It is highly recommended that the internal battery in the
TFXP be fully charged before using the meter for the first
time. Details covering this procedure are located on
Page 1.1 of this manual.
1. The connectors located on the side of the TFXP consist of three 1/4 turn BNC-type and one 5.5mm power
plug. These connectors are environmentally sealed,
but it is recommended not to allow water or other liquids to collect in the electrical connections pocket.
Figure 1.4
2. Connect the appropriate wires to the corresponding
connections on the transmitter. The transducer cable
has markings of UPSTREAM and DOWNSTREAM to
assist in the installation process. The UPSTREAM
transducer is the one located closer to the direction
from which fluid flow normally comes from (The fluid
normally passes the UPSTREAM transducer before
passing the DOWNSTREAM transducer.) If the transducer wires are connected backwards, a negative flow
indication will be observed on the flow meter display.
See Figure 1.4 or the Wiring Diagram located on the
inner door of the transmitter.
NOTE: The transducer cables carry low level signals. Do
not attempt to add additional cable to the factory supplied
transducer cable. If additional cable is required, contact
the Dynasonics factory to arrange for an exchange transducer with the appropriate length of cable. Cables to 990
feet [ 300 meters ] are available.
Battery Charging and
External Power
Sources
Rev. 4/01
The 12 Volt DC power converter and 12 Volt cigarettestyle power cord connect to the socket connection located
on the side of the enclosure. See Figure 1.4. A fully
charged battery will provide up to 24 hours of continuous
operation before recharging will be necessary. When the
battery level has decreased to a point where recharging is
required, the LOW BATTERY indicator will illuminate on
the front panel. At that point, the meter will only operate a
short time more until it automatically turns itself off—
preventing excessive battery discharge that can damage
-1.10-
TFXP
PART 1 - TFXP TRANSMITTER CONNECTIONS
the Gel Cell battery.
If the TFXP is to be used for extended periods of operation, the 12 Vdc line power converter or the 12 V cigarette
converter can remain connected indefinitely.
To charge the internal Gel Cell battery, apply power, utilizing the enclosed 12 Vdc line power converter or cigarettestyle power cord, to the TFXP for a period of 16-24 hours.
The TFXP has an integral charging circuit that prevents
overcharging. The instrument can be permanently connected to AC line power without damaging the flow meter
or the battery.
The Gel Cell battery is “maintenance free”, but it still requires a certain amount of attention to prolong its useful
life. To obtain the greatest capacity and longevity from the
battery, the following practices are recommended:
•
Do not allow the battery to completely discharge.
(Discharging the battery to the point where the LOW
BATTERY indicator illuminates will not damage the
battery. Allowing the battery to remain discharged for
long periods of time can degrade the storage capacity
of the battery.) When not in use, continually charge
the battery by keeping the 12 Vdc line power converter
plugged in and connected to the flow meter. The
TFXP battery management circuitry will not allow the
battery to become “over-charged”.
NOTE: The TFXP will automatically enter a low power
consumption mode approximately 1-1/2 minutes after the
LOW BATTERY indicator illuminates. This circuit prevents excessive discharge of the internal battery.
•
If the TFXP is stored for prolonged periods of time,
monthly charging is recommended.
•
If the TFXP is stored for prolonged periods of time,
store at a temperature below 70ºF [21ºC].
Use wiring practices that conform to local codes (National
Electric Code Handbook in the USA). Use only the power
converters that have been supplied with the TFXP flow
meter. The ground terminal, if present on the converter, is
mandatory for safe operation.

PART 1 - TFXP TRANSMITTER CONNECTIONS
CAUTION: Any other wiring method may be unsafe or
cause improper operation of the instrument.
It is recommended not to run line power with other signal
wires within the same wiring tray or conduit.
NOTE: This instrument requires clean electrical line
power. Do not operate this unit on circuits with noisy components (i.e. Fluorescent lights, relays, compressors, variable frequency drives, etc.).
The TFXP can be operated from a 11-15 Vdc source, using the included cigarette-style power cord, as long as it is
capable of supplying at least 3 Watts—observe proper polarity.

General Information
Regarding Input/
Output: ISO-MODs
The TFXP flow meter contains two Isolated Input/output
Modules (ISO-MODs); one located inside of the flow meter
enclosure and one that is user accessible, located under
the access door on the keyboard. The standard configuration of these modules is to have the internal module
configured as an actively powered 4-20 mA module and
the user accessible one as a Data Logger.
ISO-MODs are epoxy encapsulated electronic input/output
modules that are simple to install and replace in the field.
All modules are 2,500 volt optically isolated from TFXP
power and Earth grounds -- eliminating the potential for
ground loops and reducing the chance of severe damage
in the event of an electrical surge.
Seven ISO-MOD options are available including: 4-20 mA,
dual-relay, rate pulse, RS232C, RS485, 200k event datalogger and RTD heat-delivered option. TFXP supports
any two ISO-MOD input/output modules. All modules are
field configurable by utilizing the keyboard or ULTRALINK
interface. Field wiring connections to ISO-MODs are
quick and easy using pluggable terminals. Features of the
various ISO-MODs are described below. See the Series
TFXH addendum for details regarding the RTD Heatflow
Module option.
Standard
4-20 mA Output
Figure 1.5
Rev. 4/01
The 4-20 mA Output Module interfaces with virtually all recording and logging systems by transmitting an analog
current signal that is proportional to system flow rate. Independent 4 mA and 20 mA span settings are established
in software using the FL 4MA and FL 20MA settings in the
OUTPUT2 configuration menu. These entries can be set
anywhere in the –40 to +40 fps [-12 to +12 mps] measuring range of the instrument. Output resolution of the module is 12-bits (4,096 discrete points). The module can
drive more than 800 ohms of load with its internally generated 24 volt power source.
A 4-20 mA output interface cable has been included with
the TFXP package. Connect the 1/4-turn BNC connection
to the jack located on the side of the flow meter. See Figure 1.5. The red clip on the cable provides the positive
-1.13-
TFXP
PART 1 - TFXP TRANSMITTER CONNECTIONS
leg of the output and the black clip provides the negative
side. Verify that the sum of the resistances in the loop do
not exceed 800 Ohms.
Refer to Section 3 of this manual for detailed information
regarding the configuration, calibration and testing of the
4-20 mA output.
Standard
Data Logger
Figure 1.6
A 200,000-event data logger/electronic stripchart recorder
is located within the weather-tight pocket on the face plate
of the flow meter. See Figure 1.6. Loosen the three
thumbscrews located in the corners of the pocket cover
and rotate the cover to expose the Data Logger module.
The logger stores time-stamped, high resolution (16-bit)
data at user selected intervals ranging from 1 to 30,000
(8.33 hours) seconds. Configuration of and data retrieval
from the logger can be accomplished in one of two ways:
•
The module is hot-swappable -- that is, it can be installed, removed from or replaced within the flow meter
without disconnecting power. The module can be carried in a shirt pocket back to the office and plugged
into a PC serial port via the module's integral DB9 connector.
•
Via the DataLink software utility and the serial DB9 interface cable included with the logger. Data can be accessed by connecting the cable to the logger, which is
located in the pocket on the front faceplate of the instrument. See Figure 1.6.
Refer to Section 3 of this manual for detailed information
regarding the configuration and operation of the Data Logger Module.
Optional
Control Relay
Rev. 4/01
Two independent SPDT (single-pole, double-throw, Form
C) relays are contained in this module. The relay operations are user configured via software to act in either a
-1.14-
TFXP
PART 1 - ISO-MOD
flow rate alarm, signal strength alarm or totalizer/batching
mode. The relays are rated for 200 Vac max. and have a
current rating of 0.5 A resistive load [175 Vdc @ 0.25 A resistive]. It is highly recommended that a slave relay be
utilized whenever the Control Relay ISO-MOD is used to
control inductive loads such as solenoids and motors.
Optional
0-10 kHz Output
The Rate Pulse Output Module is utilized to transmit information to external counters and PID systems via a frequency output that is proportional to system flow rate.
This module does not source voltage at its output, it must
be connected in an “open-collector” fashion with an external power source and pull-up resistor. Independent Zero
and Span settings are established in software using the
Flow Measuring Range entries. These entries can be set
anywhere in the –40 to +40 fps [-12 to +12 mps] measuring range of the instrument. Output resolution of the module is 12-bits (4,096 discrete points) and the maximum
output frequency setting is 10,000 Hz. The MOSFET can
support loads of 100V @ 9A.
Optional
RS232C I/O
The RS232 Module can be interfaced with the serial communication ports of PCs, PLCs and SCADA systems that
are used to monitor flow rate information in piping systems. The RS232 Module may also be used to form a
hardwire connection to a PC that is running the UltraLink
software utility. Baud rates up to 19.2k are supported.
Optional
RS485 I/O
The RS485 Module allows up to 126 TFXP systems to be
placed on a single three-wire cable bus. All meters are
assigned a unique one byte serial number that allows all
of the meters on the cable network to be independently
accessed. Baud rates up to 19.2k and cable lengths to
1,000 feet [300 meters] are supported.
Optional
RTD-BTU
See the Appendix of this manual for information regarding
connection and operation of the optional RTD-BTU option.

TFXP
PART 2 - TRANSDUCER POSITIONING
General
The transducers that are utilized by the Series TFXP
contain piezoelectric crystals for transmitting and
receiving ultrasound signals through walls of liquid
piping systems. The transducers are relatively simple
and straight-forward 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.
Mounting of the clamp-on ultrasonic transit time
transducers is comprised of three steps. In general,
these steps consist of:
1. Selection of the optimum location on a piping
system.
2. Entering the pipe and liquid parameters into either
the optional software utility (UltraLink) or keying in
the parameters into the TFXP keypad. The
software embedded in UltraLink and TFXP will
calculate proper transducer spacing based on
these entries.
3. Pipe preparation and transducer mounting.
1. Mounting Location
The first step in the installation process is the
selection of an optimum location for the flow
measurement to be made. For this to be done
effectively, a basic knowledge of the piping system
and its plumbing are required.
An optimum location would be defined as a piping
system that is completely full of liquid when
measurements are being taken and has 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.

PART 2 - TRANSDUCER POSITIONING
2. Transducer Spacing
TFXP transit time flowmeters utilize two transducers
that function as both ultrasonic transmitters and
receivers.
The transducers are clamped on the
outside of a closed pipe at a specific distance from
each other. The transducers can be mounted in Vmode where the sound transverses the pipe two times,
W-mode where the sound transverses the pipe four
times, or in Z-mode where the transducers are
mounted on opposite sides of the pipe and the sound
crosses the pipe once. See Figures 2.1-2.3. This
selection is based on pipe and liquid characteristics.
The flowmeter 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.
IMPORTANT: Since the time interval being measured
is influenced by the transducer spacing, it is critical
that the transducer spacing be measured on the pipe
accurately to assure optimum performance from the
TFXP system.
The TFXP system calculates proper transducer
spacing by utilizing piping and liquid information
entered by the user. This information can be entered
via the keypad or the UltraLink Windows software
utility and a laptop computer.
The following information will be required before
programming the instrument:
1. Transducer mounting configuration.

3. Transducer Mounting
After selecting an optimal mounting location, Step 1,
and successfully determining the proper transducer
spacing, Step 2, the transducers can now be mounted
onto the pipe.
The DTT transducers need to be properly oriented on
the pipe to provide optimum reliability and
performance. On horizontal pipes, 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 2.5. Figure 2.5 does not apply to vertically
oriented pipes.
Before the transducers are bonded to the pipe surface,
two areas slightly larger than the flat surface of the
transducer heads must be cleaned of all rust, scale
and moisture. Finish the surface with some emery
paper, and wipe the surface with a degreasing solvent
such as trichlorethylene. Paint and other coatings, if

not flaked or bubbled, need not be removed. Plastic
pipes typically do not require surface preparation other
than soap and water cleaning.
Figure 2.5 Transducer mounting locations on
horizontal pipe.
Installations on Pipes
Smaller than 10 Inches
[250 mm] Go to Page 2.18
Mounting Transducers in Z-Mount Configuration
Installation on larger pipes requires careful
measurements to the linear and radial placement of
the DTT transducers. Failure to properly orient and
place the transducers on the pipe may lead to weak
signal strength and/or inaccurate readings.
The
section below 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.
Wrap the paper around the pipe in the manner shown
in Figure 2.6. Align the paper ends to within 0.25
inches [6mm].
Mark the intersection of the two pieces of paper to
indicate the circumference. Remove the template and
spread it out on a flat surface. Fold the template in
half, bisecting the circumference. See Figure 2.7.
Rev. 4/01

PART 2 - TRANSDUCER POSITIONING
Figure 2.6 Paper Template Alignment
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 2.5 for
acceptable radial orientations. Wrap the template
back around the pipe, placing the beginning of the
paper and corner in the location of the mark. Move to
the other side of the pipe and mark the ends of the
crease. Measure from the end of the crease (directly

dimension derived in Step 2, Transducer Spacing.
Mark this location on the pipe.
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 to these dimensions and lay it over
the top of the pipe.
Length = Pipe O.D. x 1.57
Width = Spacing determined on 2.12 or 2.14
Mark opposite corners of the paper on the pipe.

Note: The TFXP flow meter system requires a full
pipe of liquid before a successful startup can be
completed. Do not attempt to make adjustments or
change configurations until a full pipe is verified.
Note: If Dow 732 RTV was utilized to couple the
transducers to the pipe, the adhesive must fully cure
before power is applied to the instrument. Dow 732
requires 24 hours to cure satisfactorily. If Dow 111
silicone grease was utilized as a couplant, the curing time
is not required.
Instrument Startup
Procedure:
1. Verify that all wiring is properly connected and routed
as described previously in this manual.
2. Verify that the transducers are properly mounted as
described in Part 2 of this manual.
3. Press the ON button on the flow meter keypad. The
TFXP display backlighting will illuminate and the
software version number and Dynasonics’ logo will
appear on the display.
The display backlighting illuminates for approximately 20
seconds and automatically extinguishes to preserve
battery power. To re illuminate the display, press any key
on the keyboard. Adjustments to the backlighting duration
can be made in the Display Menu. Refer to page 3.27 for
details.
4. Confirm that Signal Strength is greater than 2%. If it
is not, verify that proper transducer mounting methods
and liquid/pipe characteristics have been entered.
The pipe must be full of liquid in order to make
this measurement.

ISO-MOD DataLogger
Location Number 1-30,000 [16 total locations]
INTERVAL 1-30,000 seconds
DURATION 1-30,000 hours
The standard configuration for the TFXP includes a
powerful 200,000-event data logger/electronic stripchart recorder. The logger can be configured in a couple of different ways to match user applications. The
logger stores time-stamped, high resolution (16-bit)
data at user selected intervals ranging from 1 to
30,000 (8.33 hours) seconds. Configuration of and
data retrieval from the logger can be accomplished in
one of two ways:
•
The module is hot-swappable -- that is, it can be
installed, removed from or replaced within the flow
meter without disconnecting power. The module
can be carried in a shirt pocket back to the office
and plugged into a PC serial port via the module's
integral DB9 connector. This feature eliminates the
requirement to carry a laptop computer to the flowmeter site.
•
Via the DataLink software utility and the serial DB9
interface cable included with the logger. Data can
be accessed by connecting the cable to the logger,
which is located in the pocket on the front faceplate
of the instrument. See Figure 3.3

write over an existing file. Existing data files will need
to be uploaded and then erased from the logger before
new data can be written into the space. Uploading
and storing of datalogger files is completed using the
DataLink software utility. See Section 4 of this manual for details regarding operation of the DataLink and
UltraLink software utilities.
Logging Interval
From the OUTPUT 1 menu, adjust the time INTERVAL
between readings. INTERVAL values between 1 and

4-20 TST
The 4-20 mA Output Module interfaces with virtually all
recording and logging systems by transmitting an analog current signal that is proportional to system flow
rate. Independent 4 mA and 20 mA span settings are
established in software using the Flow Measuring
Range entries. These entries can be set anywhere in
the –40 to +40 FPS [-12 to +12 MPS] measuring range
of the instrument. Output resolution of the module is
12-bits (4096 discrete points) and the module can
drive up to 800 ohms of load with its internal 24V isolated power source.
4-20mA Span
The FL 4MA and FL 20MA entries are used to set the
span of the 4-20 mA analog output. These entries are
volumetric rate units that are equal to the volumetric
units configured as Engineering Rate Units and Engineering Units Time Interval entered on page 3.10.
These entries may be entered anywhere in the flow
measurement range of the instrument (velocity range
of –40 to +40 FPS [-12 to +12 MPS]).
For example, to span the 4-20mA output from –100
GPM to +100 GPM, with 12mA being 0 GPM, set the
FL 4MA and FL 20MA inputs as follows:
FL 4MA = -100.0
FL 20MA = 100.0
For example, to span the 4-20mA output from 0 GPM

4-20mA Calibration
The 4-20mA ISO-MOD is factory calibrated and should
not require adjustment unless it is replaced.
The CAL4MA entry allows fine adjustments to be
made to the “zero” of the 4-20mA output. To adjust
the 4mA output, an ammeter or reliable reference
connection to the 4-20mA output must be present.
NOTE: The CAL 4MA and CAL 20MA entries should
not be used in a attempt to set the 4-20mA range.
Utilize FL 4MA and FL 20MA, detailed above, for this
purpose.
Procedure:
1.
Disconnect one side of the current loop and
connect the ammeter in series (disconnect either
wire at the terminals labeled +/- on the ISO-MOD 420mA module).
2. Using the arrow keys, increase the numerical value
to increase the current in the loop to 4mA. Decrease the value to decrease the current in the
loop to 4mA. Typical values range between 40-80
counts.
Re connect the 4-20mA output circuitry as required.
Calibration of the 20mA setting is conducted much the
same way as the 4mA adjustments.

entries. These entries can be set anywhere in the –40
to +40 FPS [-12 to +12 MPS] measuring range of the
instrument. Output resolution of the module is 12-bits
(4096 discrete points) and the maximum output frequency setting is 10,000 Hz. The 0.21-Ohm FET output is rated to operate at 100 V and 9 A maximum.
This module does not source an output voltage and
should be treated as an open collector type of output.
An external voltage source and limit resistor must be
present.
Rate Pulse Span
The FL 100H and FL FL10KH entries are used to set
the span of the 0-10KHz frequency output. These entries are volumetric rate units that are equal to the
volumetric units configured as Engineering Rate Units

The SERVICE Menu also has features that allow adjustment of Signal Strength Cutoff, Error-Mode outputs and Zero Flow Rate Set.
SSPD MPS - Sound Speed in the Liquid Metric
SSPD FPS - Sound Speed in the Liquid U.S.
The TFXP performs an actual speed of sound calculation for the liquid it is measuring. This speed of sound
calculation will vary with temperature, pressure and
fluid composition. The value indicated in this measurement should be within a couple of percent of the
value entered/indicated in the BASIC menu item
FLUID SS. This value cannot be modified.
Signal Strength
SIG STR - Signal Strength
The measurement of Signal Strength assists service
personnel with troubleshooting the TFXP system. In
general, expect the signal strength readings to be
greater than 5% on a full pipe with the transducers
properly mounted. Signal strength readings that are
less than 5% may indicate a need to chose an alternative mounting method for the transducers or that an
improper pipe size has been entered.
Signal Strength readings in excess of 95% may indicate that a mounting method with a longer path length
may be required. For example, if mounted on a 3
inch PVC pipe in V-mode causes the measured Signal Strength value to exceed 95%, change the mounting method to W-mode for greater stability in readings.

Signal Strength
Cutoff
Signal Strength Cutoff SIG C-OF is used to drive the
flowmeter and its outputs to a zero flow state should
conditions occur that cause low signal strength. A
signal strength indication of between 0.5 and 0.8 is
considered to be inadequate for measuring flow reliably, so typical settings for SIG C-OF are in the range
of 1.0 to 2.0.
Signal Strength indication of 0.5 to 0.8 is considered to
be no signal at all. Verify that the pipe if full of liquid,
the pipe size and liquid parameters are entered correctly and that the transducers have been mounted accurately.
Substitute Flow
Entry
Substitute Flow or SUB FLOW is a value that the analog outputs will be driven at when an error condition in
the flowmeter occurs. Typical settings are either –5%
or 105% - a value outside of the normal operating
range that can be used to indicate a fault condition to
the target device.
Setting/Calibrating
Zero Flow
Because every flowmeter installation is slightly different and sound waves can travel in slightly different
ways through these various installations, a provision
is made in this entry to establish “Zero” flow—SET
ZERO.
To zero the meter:
1. The pipe must be full of liquid.
2. Flow must be absolute zero—verify by closing a
valve securely. Allow time for any settling to occur.

flow meter and requires meter disassembly in order to
replace the module. The data logger is located under
the sealed front plate on the meter face. The logger is
designed for repeated installation and removal.) Detailed information regarding all of the modules available and configuration options are available in section

Field Calibration
UltraLink contains a powerful multi-point calibration routine that can be used to calibrate the TFX flow meter to a
primary measuring standard in a particular installation. To
initialize the three step calibration routine, press the Edit
menu located on the top task bar. Select the Calibration
option. The display shown in Figure 4.7 will appear. The
first step in the calibration process is the selection of the
engineering units that the calibration will be performed
with. Select the units and press the Next button at the
bottom of the window.

The second screen, Figure 4.8, establishes a baseline
zero flow rate measurement for the instrument. To zero
the flow meter, establish zero flow in the pipe (turn off all
pumps and close a dead heading valve). Wait until the
delta-time interval shown in Figure 4.8 is stable (and typically very close to zero). Press the Set button. Press the
Next button when complete.
The screen shown in Figure 4.9 allows multiple actual
flow rates to be run past the meter and the values recorded by the TFXP. To calibrate a point, establish a stable known flow rate (verified by a real-time primary flow
instrument), enter the actual flow rate in the Figure 4.9

points as desired. Note: If only two points are to be used
(zero and span), it is preferred that a flow rate as high as
anticipated in normal operation is used as the calibration
point. If an erroneous data point is collected, the point
can be removed by pressing the Edit button, selecting the
bad point and selecting Remove.

Addendum — Heat Flow
Dynasonics Series TFX Heat Flow
General
The TFX flowmeter with the optional heat flow module installed is designed to measure the rate and quantity of heat delivered to a given building, area or heat exchanger.
The instrument measures the volumetric flow rate of the heat exchanger liquid (water,
water/glycol mixture, brine, etc.), the temperature at the inlet pipe and the temperature
at the outlet pipe. Heat delivery is calculated by the following equation:
Rate of heat delivery = Q*(Tin – Tout)*c
Where
Q
Tin
Tout
c
=
=

=
volumetric flow rate
temperature at the inlet
temperature at the outlet
specific heat of the liquid
The RTD module installed in the TFX measures the differential temperature of two
1000-ohm three-wire platinum RTDs. The three-wire configuration allows the temperature sensors to be located several hundred feet away from the TFX meter without
influencing system accuracy or stability. The TFX transit time flow meter can also tolerate large distances between the flow measurement transducers and the electronic
instrument.
The RTDs included with the TFX heat delivered flowmeter have been factory calibrated and are marked with an identification as to which terminal, #1 or #2, the RTD
has been calibrated. The RTDs are 1000-ohm platinum and are designed to be
mounted on the exterior surface of the pipe. The RTDs are rated for a temperature
range of –50 to +130 C.
Installation
1. Follow the instructions outlined in the standard TFX manual for proper installation
of the flow measurement transducers. After installation, verify that the Signal
Strength is greater than 4-5% and, if possible, perform a Zero flow calibration on
the pipe. Please note that all readings require a full pipe of liquid.
2. Select areas on the inlet and outlet pipes where the RTDs will be mounted. Remove or peel back the insulation all the way around the pipe in the installation
area. Clean an area slightly larger than the RTD down to bare metal on the pipe.

3. Place a small amount of heat sink
compound on the pipe in the RTD installation location. See Figure 1.
Press the RTD firmly into the compound. Fasten the RTD to the pipe
with the included heater tape.
4. Route the RTD wires to an electrical
junction box in close proximity to the
installation location. Secure the RTD
wires such that they will not be pulled
on or abraded inadvertently. Replace the insulation on the pipe.
5. Route a cable from the electrical
junction box back to the TFX flowmeter. Connect the RTDs as illustrated in Figure 2. Note that the
SNS1 and DRV1 wires originate from
the same location on the RTD.

1. The RTDs included with the TFX heat
delivered flowmeter have been factory
calibrated and are marked with an
identification as to which terminal, #1
or #2, the RTD has been calibrated.
If recalibration of the RTDs is required
or RTDs other than those supplied
with the TFX are being utilized, the
UltraLink software utility will be required. UltraLink can also be used to
configure all operating parameters of
the heat flow instrument.

2. To properly measure heat delivery,
the specific heat capacity of the liquid
Figure 2
must be entered. When a liquid is
chosen from the FL TYPE list, a default specific heat will be loaded. This default value is displayed as SP HEAT in the
BASIC MENU. If the actual specific heat of the liquid is known or if it differs from
the default value, press the ENTER key and modify the value. Press the enter key
to save the value. See the values listed in Tables 1 and 2 for specific values. Enter
a value that is the mean of both pipes.

3. The RATE UNIT can be displayed as three different values; BTUs, CALs or Watts.
Select the proper unit from the RATE UNIT list. Select the appropriate RATE INTERVAL from the list (seconds, minutes, hours, days). Be aware that the instrument can only display values as large as 99,999,999.
4. Select an appropriate TOTALIZER UNIT from the list; BTU, CAL, Watt.
5. In the SER MENU three values can be displayed that may aid in troubleshooting
the heatflow instrument. In this menu, the temperature being read by RTD1 is indicated as TEMP1 (all values are degrees Celsius) , RTD2 as TEMP2 and the absolute difference as TEMPDIFF.
