QUICKSTART OPERATING OVERVIEW
Items Required for Basic Installation and Conguration
• TFXL meter
• Transducers (remote-mount versions sold separately)
• Mounting straps (for remote-mount versions)
• Acoustic couplant
• Power source
• UltraLink Software
• Configuration cable kit P/N D010-0204-001
• USB-to-DB9 converter P/N D005-2116-004 (required if PC does not have a serial port)
• Phillips screwdriver
• Flathead screwdrivers (large and small)
• 5/16 in. nut driver (optional, for remote-mount versions)
Follow these instructions to get the system up and running quickly. Refer to the detailed instructions if you require
additional information.
OTE:NThe following steps require information supplied by the transmitter itself so it will be necessary to supply power
to the transmitter, at least temporarily, and connect to a computer using the UltraLink® software utility to obtain
setup information.
Transducer Location
1. Select a mounting location on the piping system with a minimum of ten pipe diameters (10 × the pipe inside diameter) of
straight pipe upstream and ve straight diameters downstream. See Table 1 on page 16 for additional congurations.
2. If the application requires DTTR, DTTN or DTTH transducers, select a mounting method for the transducers based on pipe
size and liquid characteristics. See Table 2 on page 17. The three transducer mounting congurations are shown in
Figure 4. See “Transducer Mounting Configurations” on page 20 for mounting procedures.
OTE:NAll DTTS and DTTC transducers use V–Mount configuration.
Power Connections
Power for the TFXL meter flow meter is obtained from a direct current (DC) power source.
1. Verify that the power source is capable of supplying 12…28V DC at a minimum of 250 milliamps.
2. 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. A wiring diagram decal is on the inside cover of the ow
meter enclosure.

Transducer Connections for Remote Mount Transducers
1. Guide the transducer terminations through the transmitter conduit hole on the bottom-left of the enclosure using a
sealed cord grip or NEMA 4 conduit connection. Secure the transducer cable with the supplied conduit nut (if exible
conduit was ordered with the transducer).

2. The remote mount transducers use an add-in connection board on the left side of the meter below the LCD (TFXL meter
2 version). The terminals within the TFXL meter are of a screw-down barrier terminal type. Connect the wires at the
corresponding screw terminals in the transmitter. Observe upstream and downstream orientation and wire polarity. See
Figure 2 on page 7.

Pipe Preparation and Transducer Mounting
DTTR, DTTN and DTTH Transducers
1. Place the transmitter in signal strength measuring mode.
This value is available on the data display of 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 mounting location within
approximately 45 degrees of the side of the pipe.
See Figure 5 on page 9. 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 1/2 inch (12 mm) bead of acoustic couplant
grease to the upstream transducer and secure it to the pipe with
a mounting strap.

4. Apply acoustic couplant grease to the downstream transducer and press it onto the pipe using hand pressure at the lineal
distance calculated in “Transducer Location” on page 6.
5. Space the transducers according to the recommended values from the UltraLink software utility. Secure the transducers
with the mounting straps at these locations.

3. Apply a single 1/2 inch (12 mm) bead of acoustic couplant grease to the top half of the transducer and secure it to the pipe
with the bottom half or with U-bolts.
4. Tighten the nuts so the acoustic coupling grease begins to ow out from the edges of the transducer and from the gap
between the transducer and the pipe.
MPORTANTI
Do not overtighten. Overtightening will not improve performance and may damage the transducer.
5. Verify that signal strength is greater than 5.0.
6. Input the units of measure and the I/O data.

INTRODUCTION
The TFXL meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-
contacting, clamp-on or clamp-around type, which provide the benefits of non-fouling operation and ease of installation.
The TFXL meter family of transit time transmitters uses 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-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 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 effect
on how much signal is generated. The flow 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 difference in the time interval measured is directly related to the velocity of the liquid in the pipe.
Application Versatility
The TFXL 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 1/2 …100 inches (12…2540 mm)*. A variety of liquid
applications can be accommodated:
ultrapure liquids cooling water potable water river water chemicals
plant effluent sewage reclaimed water others
Because the transducers are non-contacting and have no moving parts, the transmitter is not affected by system pressure,
fouling or wear.
Temperature Ratings for Transducers
Because the transducers are non-contacting and have no moving parts, the flow meter is not affected by system pressure,
fouling or wear. Temperature ratings for each transducer are listed below.
Transducer Temperature Rating
DTTR –40…250° F (–40…121° C)
DTTC –40…194° F (–40…90° C)
DTTN –40…194° F (–40…90° C)
DTTH –40…350° F (–40…177° C)
DTTS –40…140° F (–40…60° C)
User Safety
The TFXL meter uses a low voltage DC power source that provides electrical safety for the user. Remove the cover to access to
the meter connections and the computer interface connection.
DANGER
THE POWER SUPPLY BOARD CAN HAVE LINE VOLTAGES APPLIED TO IT, SO DISCONNECT ELECTRICAL POWER BEFORE
OPENING THE INSTRUMENT ENCLOSURE. WIRING SHOULD ALWAYS CONFORM TO LOCAL CODES AND THE NATIONAL
ELECTRICAL CODE.
Data Integrity
Non-volatile flash memory retains all user-entered configuration values in memory indefinitely, even if power is lost or
turned off.
Product Identication
The serial number and complete model number of the transmitter are located on the top outside surface of the transmitter
body. Should technical assistance be required, please provide our customer service department with this information.
