The 24V DC power converter and 12V auto-style power cord connect to the 3-pin socket connection located on the back of
the enclosure. A fully charged battery provides up to 9 hours of continuous operation before recharging is necessary.
At that point, the meter operates for only a short time more until it automatically turns itself off.
If the flow meter is to be used for extended periods of operation, the 24V DC line power converter or the 12V auto-style
converter can remain connected indefinitely.
To charge the internal Lithium-Ion Smart battery, apply power, using the enclosed 24V DC line power converter or auto style
power cord, to the flow meter for a period of 4 hours with the unit off. The flow meter has an integral charging circuit that
prevents overcharging. The flow meter can be permanently connected to an AC line power without damaging the meter or
the battery.
The Lithium-Ion Smart 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:
• When charging or using external power, allow for airflow to the instrument.
• The flow meter’s battery management circuitry does not allow the battery to become overcharged.
• The lithium-ion battery is rated for 300 cycles, but may last much longer than that. Cycle counts are shown in the
system menu.
• If the meter is stored for prolonged periods of time:
• Recharge the battery every 6 months and recharge before use.
• Store at room temperature. Extended exposure above 104° F (40° C) can degrade battery life.
• Do not expose unit to temperatures beyond those specified.
• Battery should only be replaced by authorized personnel.
• In the unlikely event that smoke, abnormal noise or strange odor is present, immediately power off the DXN and
disconnect all power sources. Report the problem to your device provider immediately.
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 flow meter. The ground terminal, if present on the converter, is mandatory for
safe operation.
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.
OTE:N The flow meter requires clean electrical line power. Do not operate the meter on circuits with noisy components (for
example, fluorescent lights, relays, compressors, variable frequency drives and like equipment).
The flow meter can be operated from a 10…15V DC source, using the included auto-style power cord, as long as it is capable
of supplying at least 40 watts. Observe proper polarity. Note that extended operation on an automotive supply could
substantially reduce the automotive battery.
WARNING
THE INTERNAL BATTERY PACK SHOULD ONLY BE REPLACED BY AN AUTHORIZED BADGER METER SERVICE

Meter Overview
METER OVERVIEW
General
The DXN portable ultrasonic flow meter is designed to measure volumetric flow rate 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.
In Transit Time mode, the flow meter 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 transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.
The selection of mounting 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.
Internally, volumetric flow rate is derived from fluid velocity and the cross-sectional area of the pipe inner diameter.
Application Versatility
The flow meter can be successfully applied on a wide range of metering applications because the meter has both transit time
and Doppler capabilities. A full range of fluids—from ultrapure to thick slurries—can be measured.
The flow meter can be used on pipe sizes ranging from 0.5…120" (12…3048 mm) while accommodating a wide variety of
liquid applications:
ultrapure liquids cooling water potable water river water
chemicals plant effluent sewage sludge
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)
DTTN –40…185° F (–40…85° C)
DTTL –40…194° F (–40…90° C)
DTTSU –40…194° F (–40…90° C)
DT94 –40…194° F (–40…90° C)
DTTH –40…350° F (–40…176° C)
OTE:N When the type of transducer is selected, the flow meter automatically chooses the correct transmission frequency for
that transducer set.
Data Integrity
Non-volatile flash memory retains all user-entered configuration values in memory for several years at 77° F (25° C), even if
power is lost or turned off.

Transducer Installation
TRANSDUCER INSTALLATION
The transducers for the DXN flow meter contain piezoelectric crystals that transmit and receive ultrasonic signals through the
walls of liquid piping systems.
DTTR, DTTN, DTTL, DTTH and DT94 transducers are relatively simple and straightforward to install, but spacing and alignment
of the transducers is critical to the system’s accuracy and performance. CAREFULLY PERFORM THESE INSTRUCTIONS.
DTTSU small pipe transducers have integrated transmitter and receiver elements. A spacing slider is provided to adjust the
required spacing, based on pipe size and mounting method.
Mounting the DTTR, DTTN, DTTL, DTTH and DT94 clamp-on ultrasonic transit time transducers takes four steps:
1. Select the optimum transmission mode and mounting location on a piping system.
2. Select a mounting conguration.
3. Enter the site information, then the uid pipe properties for the specic site.
4. Prepare the pipe and mount the transducers.
Select a Transmission Mode
The first decision to be made is what mode of ultrasonic transmission to use.
• Use Transit Time mode with fluids that have little to no particulates or entrained air.
• Use Doppler mode with fluids that contain significant levels of particulates and aerated fluids.
• Use Hybrid mode to automatically switch between Transit Time and Doppler modes.
If the fluid type is unknown, start with Transit Time mode, which is more forgiving of having some particulate or air than
Doppler mode is of not having enough particulate or entrained air.
If the fluid type is an unknown, you can mount both Transit Time and Doppler transducers on the same pipe and let the flow
meter decide which set of transducers to use. The flow meter can operate as a dedicated Transit Time meter, a dedicated
Doppler meter or it can automatically switch between Transit Time and Doppler modes using the Hybrid mode.
Signal Quality
When the flow meter is in Hybrid mode, switching between Transit Time and Doppler modes is controlled by the signal quality.
For any mode setting elected from the Meter > Flow page, the signal quality myst be at least 10% to obtain any readings.
Above a signal quality of 10%, but below 40%, the flow meter uses the mode that develops the hightest signal quality. If, for
example, the Doppler signal quality is 38% and Transit Time signal quality is 33%, Doppler is automatically selected. Above
40%, the flow meter uses Transit Time.
Page 17 August 2018 HYB-UM-00090-EN-05
Transducer Installation
Select a Mounting Location
At this point, consider the transducer mounting location. A guiding principle is to mount the transducers on a section of pipe
that has at least 10 pipe diameters upstream of the transducers and 5 pipe diameters downstream. See Table 1 on page19
for additional pipe length considerations.
For example, if a 3 inch pipe is being measured, the minimum upstream pipe in front of the transducers should be 30 inches
and the minimum downstream pipe behind the transducers should be at least 15 inches.
Pipe runs shorter than the minimums may sometimes be used with reduced accuracy. There is no way to determine how
much accuracy is sacrificed without doing in-field testing. For installations where the 10/5 pipe diameters rule cannot
be followed, divide the total length of available straight pipe into thirds and mount the transducers with 2/3 of the pipe
upstream and 1/3 of the pipe downstream.
A full pipe is absolutely essential for making accurate flow measurements in either Transit Time and Doppler mode. The flow
meter cannot determine if the pipe is full or not. If the pipe is partially full, the meter will over report the amount of flow by
the percentage of the pipe that is not filled with liquid.
An optimum transducer mounting location is defined as:
• A piping system that is completely full of liquid when measurements are being taken. The pipe may become empty during
a process cycle, which results in a “Low Signal Strength” error while the pipe is empty. This error code clears automatically
when the pipe refills with liquid. Do not mount the transducers in an area where the pipe may become partially filled.
Partially filled pipes cause erroneous and unpredictable operation of the meter.
• A piping system that contains lengths of straight pipe such as those described in Table 1 on page19. The optimum
straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation. The straight runs in
Table 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.
• Mount the transducers in an area where they will not be inadvertently bumped or disturbed.
• Avoid installations on downward flowing pipes unless adequate downstream head pressure is present to overcome partial
filling of or cavitation in the pipe.

Transducer Installation
Select a Mounting Conguration
The flow meter can be used with these transducer types: DTTR, DTTN, DTTL, DTTH, DTTSU and DT94. Meters that use
transducer sets consist of two separate sensors 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:
• 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
yields the best signal strength but the smallest relative travel time.

Table 3: Transducer mounting modes for DTTSU
DTTL transducers may also be advantageous on pipes between 4…24 inches if there are less quantifiable complicating
aspects, such as sludge, tuberculation, scale, rubber liners, plastic liners, thick mortar, gas bubbles, suspended solids,
emulsions, or pipes that are partially buried where a V-mount is required or desired.
The DTTR, DTTN, DTTH and DTTL transducers must be properly oriented and spaced on the pipe to provide optimum
reliability and performance. On horizontal pipes, when Z-Mount is required, the transducers should be mounted 180 radial
degrees from one another and at least 45 degrees from the top-dead-center and bottom-dead-center of the pipe.
See Figure 24 on page25. Also see “Z-Mount Installation” on page24. On vertical pipes the orientation is not critical.
The best accuracy is achieved when transducer spacing is exactly what the flow meter calculates, so the calculated spacing
should be used if signal quality is satisfactory. If the pipe is not round, the wall thickness not correct or the actual liquid
being measured has a different 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.
OTE:N Transducer spacing is calculated on ideal pipe. Ideal pipe is almost never found so the transducer spacing distances
may need to be altered. An effective way to maximize signal quality is to configure the display to show signal quality,
fix one transducer on the pipe and then starting at the calculated spacing, move the remaining transducer small
distances forward and back to find the maximum signal quality point.

Enter the Site, Fluid and Pipe Properties
The DXN has the ability to store over 300 sites. Each site contains uid and piping characteristics as well as other settings that
are congured during meter commissioning. Sites are recallable from a pull-down menu each time the specic site is visited.
This makes period measurements of the particular site less time consuming. For further detail on sites, see “Site Page” on
page37.
The DXN flow metering system calculates proper transducer spacing based on the piping and mounting method information
you enter into the ow meter via the touchscreen display.
The most accuracy is achieved when the transducer spacing is exactly what the flow meter calculates, so use the calculated
spacing if the signal strength is satisfactory. If the pipe is not round, the wall thickness not correct or the actual liquid being
measured has a different sound speed than the liquid programmed into the flow meter, the spacing can vary from the
calculated value. In that case, place the transducers at the highest signal level observed when moving the transducers slowly
around the mount area.
OTE:N Transducer spacing is calculated on “ideal” pipe. Ideal pipe almost never exists, so you may need to alter the
transducer spacing. An effective way to maximize signal strength is to configure the display to show signal strength,
fix one transducer on the pipe and then—starting at the calculated spacing—move the remaining transducer small
distances forward and back to find the maximum signal strength point.

Transducer Installation
Mount the Transducer
After selecting an optimal mounting location and determining the proper transducer spacing, mount the transducers onto
the pipe.
1. Clean the surface of the pipe. If the pipe has external corrosion or dirt, wire brush, sand or grind the mounting location
until it is smooth and clean. 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.
2. Orient and space the transducers on the pipe to provide optimum reliability and performance. On horizontal pipes, when
Z-Mount is required, mount the transducers 180 radial degrees from one another and at least 45 degrees from the
top-dead-center and bottom-dead-center of the pipe. See Figure 17 on page21. Also see “Z-Mount Installation” on
page24. On vertical pipes, the orientation is not critical.
The spacing between the transducers is measured between the two spacing marks on the sides of the transducers. These
marks are approximately 0.75 inches (19 mm) back from the nose of the DTTR, DTTN and DTTH transducers, and 1.2 inches
(30 mm) back from the nose of the DTTL transducers.

Apply the Couplant
For DTTR, DTTN, DTTL and DTTH transducers, place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the
flat face of the transducer. See Figure 20. 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 operating temperature of the pipe is acceptable. For pipe surface
temperature over 130° F (55° C), use Sonotemp® (P.N. D002-2011-010).

Position and Secure the Transducer
1. Place the upstream transducer in position and secure with a mounting strap. Place the straps in the arched groove on the
end of the transducer. Use the screw provided to help hold the transducer onto the strap. Verify that the transducer is true
to the pipe and adjust as necessary. Tighten the transducer strap securely.
2. Using the alignment marks, place the downstream transducer on the pipe at the calculated transducer spacing. See
Figure 21 on page24. Apply rm hand pressure. If signal strength is greater than 10%, secure the transducer at this
location. If the signal strength is not greater than 10%, using rm hand pressure, slowly move the transducer both towards
and away from the upstream transducer while observing signal strength.
Signal strength can be displayed on the ow meter’s display. Clamp the transducer at the position where the highest
signal strength is observed. The factory default signal strength setting is 10%. However, there are many applicationspecic conditions that may prevent the signal strength from attaining this level. Signal levels less than 10% are not
acceptable for reliable readings.
OTE:N Signal strength readings update only every few seconds. Move the transducer 1/8 inch, then wait to see if the signal
is increasing or decreasing. Repeat until the highest level is achieved.
3. If, after adjusting the transducers, the signal strength does not rise to 10%, use an alternate transducer mounting
conguration. If the mounting conguration was W-Mount, re-congure the ow meter for V-Mount, move the
downstream transducer to the new spacing distance and repeat the procedure “Enter the Site, Fluid and Pipe Properties” on
page22.

Spacing
OTE:N Use the DTTL transducer on pipes 24 inches and
larger and not on pipes smaller than 4 inches. You
can consider using the DTTL transducers on pipes
smaller than 24 inches if there are less quantifiable
aspects—such as sludge, tuberculation, scale, rubber
liners, plastic liners, thick mortar liners, gas bubbles,
suspended solids, emulsions—and smaller pipes
that are perhaps partially buried where a V-Mount is
required or desired.
Installation on larger pipes requires careful measurements of the linear and radial placement of the DTTR, DTTN, DTTL 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 22. Align the paper ends to within 1/4 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 23.
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 17 for acceptable radial orientations. Wrap the template back around the pipe, placing the beginning of the
paper and one corner in the location of the mark. Move to the other side of the pipe and mark the pipe at the ends of
the crease. Measure from the end of the crease (directly across the pipe from the rst transducer location) the dimension
derived in “Select a Mounting Configuration” on page20. Mark this location on the pipe.
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 1/2 the circumference of the pipe and lay it over the
top of the pipe. The equation for the length of 1/2 the circumference is: 1/2 Circumference = Pipe O.D. × 1.57
The transducer spacing is the required spacing value that was recorded during setup. Mark opposite corners of the paper on
the pipe. Apply transducers to these two marks.

couplant, approximately 1/2 inch (12 mm) thick, on the at face of the
transducer. See Figure 20. Generally, a silicone-based grease is used
as an acoustic couplant, but any good quality grease-like substance

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 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.
Figure 24: Z-Mount transducer placement
7. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 24. 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. A signal strength percentage
between 10…98 is acceptable.
The factory default signal strength setting is 10%. However, there are many application-specific 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 flow conditions.
On certain pipes, a slight twist to the transducer may cause signal strength to rise to acceptable levels. Certain pipe and
liquid characteristics may cause signal strength to rise to greater than 98. The problem with operating this flow meter with
very high signal strength is that the signals may saturate the input amplifiers 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 off-line with the other transducer to lower signal strength.
8. Secure the transducer with a stainless steel strap or other fastener.

Transducer Installation
Mounting Rail System Installation for DTTR
For remote flow DTTR transducers with outside diameters between 2…10 inches (50…250 mm), the rail mounting kit aids
in installation and positioning of the transducers. Transducers slide on the rails, which have measurement markings that are
viewable through the sight opening.
1. Install the single mounting rail on the side of the pipe with the stainless steel bands provided. Do not mount it on the top
or bottom of the pipe. On vertical pipe, orientation is not critical. Check that the track is parallel to the pipe and that all
four mounting feet are touching the pipe.
2. Slide the two transducer clamp brackets toward the center mark on the mounting rail.
3. Place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the at face of the transducer.
See Figure 20 on page23.
4. Place the rst transducer in between the mounting rails near the zero point on the scale. Slide the clamp over the
transducer. Adjust the clamp and transducer so the notch in the clamp aligns with the zero on the scale. See Figure 26.
5. Secure with the thumb screw. Check that the screw rests in the counter bore on the top of the transducer. (Excessive
pressure is not required. Apply just enough pressure so that the couplant lls the gap between the pipe and transducer.)
6. Place the second transducer in between the mounting rails near the dimension derived in the transducer spacing section,
while using the alignment marks. Read the dimension on the mounting rail scale. Slide the transducer clamp over the
transducer and secure with the thumb screw.
Figure 25: Mounting rail system for DTTR
Mounting Track Installation for DTTN/DTTH
A convenient transducer mounting track can be used for pipes that have outside diameters between 2…10 inches
(50…250 mm) or 2…16 inches (50…406 mm) and for DTTN/DTTH transducers. If the pipe is outside of that range, mount the
transducers separately.
1. Install the single mounting rail on the side of the pipe with the stainless steel bands provided. Do not mount it on the top
or bottom of the pipe. On vertical pipe, orientation is not critical. Check that the track is parallel to the pipe and that all
four mounting feet are touching the pipe.
2. Slide the two transducer clamp brackets toward the center mark on the mounting rail.
3. Place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the at face of the transducer.
See Figure 20 on page23.
4. Place the rst transducer in between the mounting rails near the zero point on the scale. Slide the clamp over the
transducer. Adjust the clamp and transducer so the notch in the clamp aligns with the zero on the scale. See Figure 26.
5. Secure with the thumb screw. Check that the screw rests in the counter bore on the top of the transducer. (Excessive
pressure is not required. Apply just enough pressure so that the couplant lls the gap between the pipe and transducer.)
6. Place the second transducer in between the mounting rails near the dimension derived in the transducer spacing section.
7. Read the dimension on the mounting rail scale. Slide the transducer clamp over the transducer and secure with the thumb
screw.

DTTSU Small Pipe Transducer Installation
Mount DTTSU transducers with the cable exiting within ±45 degrees of the side of a horizontal pipe. On vertical pipes the
orientation does not apply.
The DTTSU small pipe transducers are adjustable for pipe sizes between 1/2…2 in. (12…50 mm). Do not attempt to mount a
DTTSU transducer onto a pipe that is either too large or too small for the transducer.
1. Determine the transducer spacing required using the ow meter and the scale on the side of the DTTSU transducers, set
the spacing. See Figure 28.
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.

Do not over tighten.
5. If signal quality is less than 10%, remount the transducer at another location on the piping system.
Doppler Transducer Installation
For Doppler installation, the only pipe information needed is the Pipe Inside Diameter.
Sonic Reflectors for Doppler Mode
Flow meters based on Doppler shift principals operate by transmitting an ultrasonic sound from its transmitting transducer
through the pipe wall into the flowing liquid. The sound reflects off sonic reflectors suspended within the liquid and recorded
by the receiving transducer. If the sonic reflectors are moving within the sound transmission path, sound waves are reflected
at a frequency shifted (Doppler frequency) from the transmitted frequency. The shift in frequency is directly related to the
speed of the moving particle or bubble. This shift in frequency is interpreted by the instrument and converted to various user
defined measuring units.
The four criteria for a good Doppler reflectors are :
1. The scattering material must have a sonic impedance (sound speed dierence) dierent from the uid. The minimum
dierence must be at least 10%.
2. There must be some particles large enough to cause longitudinal reection—particles larger than 35 micron (435 mesh).
3. For a given pipe size, the longitudinal reection must have sucient energy to overcome the Rayleigh (energy wasting)
scattering caused by smaller particles.
4. The reecting material must travel at the same velocity as the uid for good accuracy.
Installation Method
Mount Doppler transducers on the pipe 180 degrees apart and facing each other, with the cables on the downstream side of
the transducers. If the pipe is horizontal, the preferred mounting orientation is 3 and 9 o’clock, with 12 o’clock being the top of
the pipe. See Figure 31. Orientation on vertical pipes does not matter.
OTE:N Doppler transducers may be mounted on the same pipe as transit time transducers without encountering acoustic
cross-talk.
1. Large pipe installations use stainless steel straps to secure the transducers to the outside of the pipe. The DXN system
is shipped with four 36 in. (900 mm) straps, which are suitable for pipes up to 39 in. (1000 mm) diameter. Select the
proper number of transducer straps to allow a complete strap to go around the circumference of the pipe. See Table 4 on
page29.
2. Wrap the strap around the pipe in the area where the transducers are to be mounted. Leave the strap loose enough to
allow the transducers to be placed underneath. If multiple straps are being used, it can be benecial to wrap electrical
tape around all but one strap connection to secure the strap worm screws in place.
3. Spread an even layer of coupling compound, approximately 1/8 in. (3 mm) thick by 1/2 in. (12 mm) wide, to the bottom
at face of the two transducers.
4. Place each transducer under the strap with the at face—amber plastic window—positioned towards the pipe. The notch
on the back of the transducer provides a mounting surface for the strap. The transducer cables must be facing in the same
direction and in the downstream direction for proper operation.

OTE:N Large pipes may require two people for this procedure.
5. Tighten the strap enough to hold the transducers in place, but not so tight that all of the couplant squeezes out of the gap
between the transducer face and pipe. Align the transducers squarely on the pipe and 180 degrees apart.
6. Route the transducer cables back to the ow meter location, avoiding high voltage cable trays and conduits.
OTE:N Where a high amount of particulates are expected mounting the transducers side-by-side may allow enough sound
reflection for the Doppler function to work.
Figure 32: Side-by-side placement
OTE:N Low particulate content may sometimes be overcome by mounting the Doppler transducers downstream of a pipe
elbow. A better solution to a low particulate fluid would be switching over to transit time measurements.
Mounting Straps
The most economical way to affix DTTR, DTTN, DTTH, DTTL and DT94 transducers to a pipe is by using adjustable mounting
straps. Individual straps in both 36 in. (900 mm) and 72 in. (1830 mm) are available from Badger Meter. See Table 4 for required
number of straps. The straps can be connected together to make a continuous length. Small pipe transducer installations do
not use straps, but use an integral clamping mechanism built into the transducer.
Pipe Size No. of 36 in. Straps Required*
1…9 in. (25…225 mm) 1
10…19 in. (250…480 mm) 2
20…29 in. (500…740 mm) 3
30…39 in. (760…1000 mm) 4
Table 4: Straps required per pipe size
OTE:N *Table 4 indicates the number of straps required to mount one transducer. For transit time installations, two
transducers must be mounted.
Doppler transducers are mounted either opposite each other or side-by-side and considered a single transducer for
calculating the number of straps required.
