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
REPRESENTATIVE. PLEASE CONTACT YOUR PRODUCT AND/OR SERVICE PROVIDER FOR INTERNAL BATTERY
REPLACEMENT 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 conguration.

3. Enter the site information, then the uid pipe properties for the specic 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 page19
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 page19. 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 Conguration

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 page25. Also see “Z-Mount Installation” on page24. 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.

Transducer Installation

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 congured during meter commissioning. Sites are recallable from a pull-down menu each time the specic site is visited.
This makes period measurements of the particular site less time consuming. For further detail on sites, see “Site Page” on

page37.

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 page21. Also see “Z-Mount Installation” on

page24. 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 page24. 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 application­specic 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
conguration. If the mounting conguration was W-Mount, re-congure 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

page22.

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 page20. 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.

transducer. See Figure 20. Generally, a silicone-based grease is used
as an acoustic couplant, but any good quality grease-like substance

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 page23.

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 page23.

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.

4. Finger tighten the thumb screws so that the acoustic coupling grease begins to ow out from the under the transducer.
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 dierence) dierent from the uid. The minimum
dierence must be at least 10%.

2. There must be some particles large enough to cause longitudinal reection—particles larger than 35 micron (435 mesh).

3. For a given pipe size, the longitudinal reection must have sucient energy to overcome the Rayleigh (energy wasting)
scattering caused by smaller particles.

4. The reecting 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

page29.

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 benecial 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.

Figure 31: Doppler transducer placement

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.

This list is provided as an example. Additional fluids are added periodically. Select a fluid from the list or select Custom, if the
fluid is not listed.

When you select a fluid from the list, the system automatically loads a nominal value for speed of sound, specific gravity,
viscosity, and specific heat capacity for that material. If actual values are known for the specific fluid system and those values
vary from the pre-defined numbers, you can revise the value by selecting the Custom fluid choice and entering the values.

Custom Fluids

When you select Custom from the Fluid list, you must enter the appropriate values for sound speed, specific gravity, viscosity
and specific heat capacity.

Page 39 August 2018 HYB-UM-00090-EN-05

Setup Group

Figure 50: Custom fluid setup

Custom Fluid Sound Speed (Numeric Value)

Enter the sound speed of the custom fluid. If English is used for the Entry Units enter the sound speed in fps. If Metric is used
the sound speed is entered in mps. The fluid sound speed is also obtained directly from the meter if the transducers are
already correctly positioned and the signal quality is above 10%. This value is available by selecting TT SOS in one of the data
panels. See Figure 49.

Custom Fluid Specific Gravity (Numeric Value)

DXN flow meters use pipe size, specific gravity and viscosity to calculate Reynolds numbers. Since the Reynolds
number influences flow profile, the DXN has to compensate for the relatively high velocities at the pipe center during
transitional or laminar flow conditions. The Specific Gravity entry is used in the calculation of Reynolds and the resultant
compensation values.

The Specific Gravity entry allows adjustments to be made to the specific gravity (density relative to water) of the liquid.

As stated previously specific gravity is used in the Reynolds correction algorithm. It is also used if mass flow measurement
units are selected for rate or total.

If a fluid is chosen from the Fluid Material list, a nominal value for specific gravity in that media is automatically loaded. If the
actual specific gravity is known for the application fluid and that value varies from the automatically loaded value, the value
can be revised.

If a custom fluid is entered, a specific gravity needs to be entered if mass flows are calculated. See “Fluid Properties” on

page107.

Dynamic Viscosity (Numeric Value Entered in cP)

If a fluid was chosen from the Fluid Material list, a default viscosity is automatically loaded. If the actual viscosity of the liquid
is known or it differs from the default value, the value can be revised. A list of alternate fluids and their associated viscosities is
located in the Appendix of this manual.

Viscosity is a measure of the resistance of a fluid to deform under either shear stress or extensional stress. It is commonly
perceived as thickness, or resistance to flow. Viscosity describes a fluid’s internal resistance to flow and may be thought of as a
measure of fluid friction.

The cgs (centimeters - grams - seconds) system uses a unit of dynamic viscosity called the poise (P). It is more commonly
expressed, particularly in ASTM standards, as centipoise (cP). The centipoise is commonly used because water has a viscosity
of 1.0020 cP (at 68° F (20° C); the closeness to one is a convenient coincidence).

The DXN uses dynamic viscosity, expressed in cP, in the calculation of Reynolds numbers and its Reynolds
correction algorithm.

Specific Heat Capacity – (Numeric Value entered in kJ/kg x °K)

Allows adjustments to be made to the specific heat capacity of the liquid.

Setup Group

If a fluid from the Fluid Material list is chosen, a default specific heat is automatically loaded. If the actual specific heat of
the liquid is known or it differs from the default value, the value can be revised. A list of alternate fluids and their associated
specific heat capacities is located in the Appendix of this manual. Enter a value that is the mean of both pipes.

Heat capacity or thermal capacity, is the physical quantity that characterizes the amount of heat required to change a
substance’s temperature by a given amount. The SI unit of heat capacity is expressed in joules per degree kelvin (J/°K).

The specific heat capacity, often simply called specific heat, is the heat capacity per unit mass of a material. Occasionally, in
engineering contexts, a volumetric heat capacity is used. The quantity used in the DXN is calculated as:

Pipe Wall [Thickness] (Numeric Value)

The Pipe Wall thickness is the value of the actual pipe wall thickness excluding any liner that may be present.

OTE:N Accurate values for Pipe OD and Pipe Wall thickness are necessary for accurate computation of the volumetric flow

rate. Without accurate pipe data, flow rates will be in error by the difference between the actual pipe cross sectional
area and the area calculated using the incorrect pipe OD or pipe wall thickness values.

Pipe Wall Thickness Gauge Automatic Use

OTE:N There are two different “reference” measurement methods required depending on the type of pipe being used. With

Tubing the reference is checked with the transducer ON pipe, for all other pipe types the reference is set with the
transducer OFF the pipe.

OTE:N Pipe thickness transducer must be applied perpendicular to the long axis of the pipe/tube (See Figure 64).

The advanced mode is intended users with knowledge of ultrasonic testing or when automatic settings are not appropriate.

To enter Advanced Mode, uncheck Automatic Analysis Mode. The manual settings reflect the automatic settings when the

Table 10: Pipe mode explanations

In Pipe Mode, you must lock the reference signal BEFORE applying the transducer to the pipe. Ultrasonic transit time is
measured as the difference in time from the ultrasound leaving the transducer face to the first reflection from the fluid-pipe
interface. The reference is detected as the large peak below a timed threshold. The largest amplitude peak is used as the
first reflection.

In Thin Pipe Mode, you must also lock the reference signal BEFORE applying the transducer to the pipe.

In Tubing Mode, you must lock the reference AFTER applying the transducer is to the pipe. Ultrasonic transit time is measured
as the difference in time between two adjacent-in-time signal reflections. The largest amplitude peak is used as the reference,
Peak 1 and Peak 2 are any detected adjacent peaks to the reference.

Supplementary Information

• Expected error is about 1.5% + 15 mils or 1.5% + 0.4 mm

• Measurement under 0.1 in. or 2.5 mm is difficult and requires special techniques (Tubing Mode and Thin Pipe Mode).

• Does not measure liner thickness.

• May not always work on all materials, conditions and fluids.

• ◊ In thin metal and metal pipe modes, the reference can disappear from the display once the transducer is applied to

the pipe. This is why the reference is locked prior to placement on pipe.

[Pipe] Roughness (Numeric Value in Micro Feet)

Surface roughness is the measure if the small surface irregularities in the pipe surface and is composed of three components:
roughness, waviness and form. These are the result of the manufacturing process employed to create the surface.

Surface roughness average (Pipe R), also known as arithmetic average (AA) is rated as the arithmetic average deviation of the
surface valleys and peaks expressed in micro inches (µ inches).

The DXN provides flow profile compensation in its flow measurement calculation. One of the components of that calculation
is roughness. The ratio of average surface imperfection as it relates to the pipe internal diameter is used in this compensation
algorithm and is found by using the following formula:

Pipe R

Inside Dia=mmeterofthe Pipe

OTE:N A microinch (µ inch) is one millionth (1/1,000,000) of an inch.

If a pipe material was chosen from the Pipe Material list, a nominal value for relative roughness in that material is
automatically loaded.

If the pipe has a roughness value that differs from standard for the pipe type, a custom value can be entered using the
Roughness controls.

sectional area and the area calculated using the incorrect pipe liner thickness.

Transducer Mount

Select the mounting pattern for the transducers from the drop-down list. An appropriate mounting pattern is based on pipe

The DXN transit time flow meters can be used with these transducer types: DTTR, DTTN, DTTH, DTTL and DTTSU. The DTTR,
DTTN, DTTH or DTTL transducer sets consist of two separate sensors that function as both ultrasonic transmitters and
receivers. DTTSU transducers integrate both sensors into one assembly. All transducers require the separation of the
transmit/receive modules be adjusted to the spacing value calculated during the DXN flow meter setup. DTTR, DTTN and
DTTL transducers are clamped on the outside of a closed pipe at a specific distance from each other.

The DTTN and DTTL 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 quality.

• V-Mount, where the sound traverses the pipe twice. V-Mount is a compromise between travel time and signal quality.

• Z-Mount, where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.

• Z-Mount, which yields the best signal quality but the smallest relative travel time.

See Table 2 on page20 for transducer mounting mode selection starting points.

Required Spacing

The spacing required between transducers is calculated by the firmware after all pipe parameters have been entered.
The value represents the one-dimensional linear measurement between the transducers (the upstream/downstream
measurement that runs parallel to the pipe). This measurement is taken between the lines that are scribed into the side of the
transducer blocks. The value is in inches for English or millimeters for Metric.

For DTTR or DTTN transducers that are mounted using the transducer track assembly, place one transducer at the 0 mark
etched into the track and the other at the calculated measurement.

Figure 67: Limit value settings

Min Flow Limit

A minimum rate setting establishes the filter software parameters and the lowest rate value to display. Volumetric entries
display in the Flow Units selected in Meter > Flow.

• For unidirectional measurements, set the Min Flow Limit to zero.

• For bidirectional measurements, set the Min Flow Limit to the highest negative (reverse) flow rate expected in the
piping system.

The flow meter does not display a flow rate at flows less than the Min Flow Limit value. As a result, if the Min Flow Limit is set to
a value greater than zero, the flow meter displays the Min Flow Limit value, even if the actual flow/energy rate is less than the
set Min Flow Limit.

For example, if the Min Flow Limit is set to 25 and the actual rate is 0, the flow meter displays 25.

If the Min Flow Limit is set to –100 and the actual flow is –200, the flow meter displays –100. This can be a problem if the
meter’s Min Flow Limit is set to a value greater than zero because at flows below the Min Flow Limit, the flow meter displays
zero flow, but the totalizer, which is not affected by the Min Flow Limit setting, continues totalizing.

Max Flow Limit

A maximum flow rate setting establishes the filter software settings and the highest rate value to display. Volumetric entries
display in the Rate Units selected in Meter > Flow.

For both unidirectional and bidirectional measurements, set the Max Flow Limit to the highest (positive) flow rate expected
in the piping system.

Low Flow Limit

A Low Flow Limit entry allows the flow meter to display very low flow rates (that can be present when pumps are off and valves
are closed) as zero flow. Typical values are 1.0…5.0% of the Min Flow Limit.

The Low Flow Limit is the minimum flow rate at which the meter gives reliable readings.

Filter Page

Figure 68: Filter settings

Filter Method

The DXN flow meter offers several levels of signal filtering:

• None imposes no filtering on the signal from the transducers.

• Simple with Rejection uses Damping and Bad Data Rejection to filter the flow data.

• Adaptive filtering allows the meter’s software routines to alter the filtering, depending on the variability of the transducer’s

signal. The Adaptive filter uses a combination of Damping, Bad Data Rejection, Sensitivity and Hysteresis to modify the flow
input data.

Damping (Range 0…100 Seconds)

Damping is the approximate amount of time the filtering routines use to attain a 99% stable rate value. Generally, the higher
the damping value, the more stable the rate readings are—but at the expense of response time.

Sensitivity (Range 0…100%)

Sensitivity determines how fast the adaptive ltering responds to a change in rate. Increasing the sensitivity decreases the
ltering, which allows the display to respond to rate changes more rapidly.

Hysteresis (Range 0…25%)

Hysteresis creates a window around the average flow measurement reading, defining the limits at which the automatic
damping increases occur. If the rate varies within the hysteresis window, greater damping occurs up to the maximum values
set by the flow filter Damping entry. The filter also establishes a flow rate window where measurements outside of the
window are captured by the Bad Data Rejection window. Enter the value as a percentage of actual flow rate.

For instance, a Hysteresis setting of 5% allows the flow to vary ± 5% from the currently established flow rate without
automatically decreasing the value of the Damping.

For example, if the average flow rate is 100 gpm and the Hysteresis is set to 10%, a filter window of 90…110 gpm is
established. Successive flow measurements that reside within that window are recorded and averaged in accordance with the

Damping setting. Flow readings outside of the window are rejected or accepted in accordance with the
Bad Data Rejection setting.

Filter settings for this example:

Filter Method Adaptive
Damping 40 seconds
Sensitivity 60%
Hysteresis 10%

Bad Data Rejection (Range 0…10 Samples)

The Bad Data Rejection setting is related to the number of successive readings that must be measured outside of a the
Hysteresis value before the flow meter considers the new flow value valid. In this example, a Hysteresis setting of 10% produces

a ± 10% band centered on the current valid flow rate of 100 gpm.

The Bad Data Rejection setting is the number of successive samples that must be outside of the Hysteresis window before
the flow meter considers the change in flow as real. Larger values are entered into the Bad Data Rejection window when
measuring liquids that contain gas bubbles, as the gas bubbles tend to disturb the ultrasonic signals and cause more
extraneous flow readings to occur. Larger Bad Data Rejection values tend to make the flow meter less responsive to rapid
changes in actual flow rate.

In Figure 71 on page56, flow data falls outside the flow Hysteresis window but does not reach the minimum time specified in
the Bad Data Rejection window. When data appears that is outside the Hysteresis band and shorter than the Bad Data Rejection
window time, the data is rejected.

The flow rate is again outside the original ±10% Hysteresis window, but the data exists for a time period greater than the
Bad Data Rejection window. In this instance, the meter interprets the data as a new valid flow rate and moves the Hysteresis

Logging Rate

The Logging Rate entry tells the flow meter how often to collect data points. The logger memory area has the capacity to store
more than 300 individual files consisting of a maximum of 65,500 points per log file.

The amount of time the logger collects data depends on the Logging Rate programmed into the flow meter. In general, the
logging time is calculated by dividing 65,563 by the number of data points recorded per minute.

The DXN flow meter’s output signals are analog or digital/pulse. Analog signals change continuously over time. Digital/

information, see Figure 80 on page61.

Select the type of I/O from the pull-down lists. The two analog outputs are 4…20 mA and 0…10V DC output. The pulse
output has a maximum frequency of 1000 Hz and can be configured as either a rate pulse or a totalizing pulse.

All outputs are scaled the same way using the I/O > Scale Out. For example, 20 mA, 1000 Hz and 0…10V all represent the same

I/O (Input / Output) Group

Flow at Min Out

Flow at Min Out sets the minimum value to which the outputs are scaled.

Flow at Max Out

Flow at Max Out sets the maximum value to which the outputs are scaled.

OTE:N Transit time measurements are capable of bidirectional flow but Doppler is not. The only time that setting the

Flow at Min Out to a negative value may be necessary is if the meter stays in Transit time mode. If the meter is used in
Doppler mode exclusively, or when in hybrid mode the meter switches to Doppler mode, set the value for
Flow at Min Out no lower than zero.

An example of a valid use of setting Flow at Min Out below zero would be a transit time application where flow can be in
either the forward or reverse direction. If, for instance, a tap water system is capable of 100 gpm forward and 100 gpm in
reverse, then setting the Flow at Min Out to –100 and Flow at Max Out to +100 would be valid entries.

If the meter were programmed to output a 4…20 mA signal, then 4 mA would represent –100 gpm and 20 mA would
represent +100 gpm. The zero flow point would be indicated as 12 mA (halfway between 4 mA and 20 mA).

Because no flow meter can read down to zero, there is going to be a small dead band around true zero where the velocity of

Whatever flow rates these velocities correspond to create the minimum dead band around true zero.

Press Set Zero (ns) zeros to remove the No Flow transit time offset. This is also referred to as Zeroing the meter.

Because every flow meter installation is slightly different and sound waves can travel in slightly different ways through these
various installations, it is important to remove the zero offset at zero flow to maintain the meter’s accuracy. To establish
Zero flow and eliminate the offset:

1. The pipe must be full of liquid.

2. Flow must be absolutely zero. Securely close any valves and allow time for any settling to occur.

3. Press Set Zero (ns) once.

User Adjustment

This allows the user to enter a calibration factor. The range can be 0.2…5.0. This adjustment modifies the indicated flow rate
by multiplying the flow rate value by the number entered into the User Adjustment field. For example, if indicated flow rate is
20 gpm, a user adjustment of “2.000” will modify the flow rate to 40 gpm.

Entry Units

Entry Units are the units of measurement for configuring meters.

Select English for inches or Metric for millimeters.

OTE:N The Entry Units are independent of the choices made to display flow rate, total, energy readings and similar units. For

example, the meter can be configured for a 2” ANSI pipe and still have the rate displayed in liters per minute (lpm).

The English/Metric selection also configures the DXN flow meter to display sound speeds in pipe materials and liquids as either
feet per second (fps) or meters per second (mps), respectively.

MPORTANTI

If the Entry Units choice has been changed from English to Metric or from Metric to English, the entry must be saved by doing a
power down and then a power up in order for the DXN flow meter to initiate the change in operating units. Failure to save and reset
the flow meter results in improper transducer-spacing calculations and an instrument that may not measure properly.

System Group

Power Page

The System > Power page has a group of lights that indicate the state of the internal Lithium-Ion battery.

The flow meter has a sophisticated battery management circuit that provides a long trouble-free battery life. The meter can
remain connected to the charger without over-charging the battery.

The page consists of four status indicator lights and a graph that shows the charge percentage and the battery temperature.
The first two lights are battery status lights and the last two indicate if the charger is connected and how many charging
cycles the battery has been through.

Figure 97: System Power

The first light stays lit as long as there is enough power remaining in the batter to run the meter. When the meter is connected
to the battery charger, the text to the right of the light says “Battery Not Being Discharged”. When the charger is removed,
the text changes to show the estimated running time before the battery becomes fully discharged. A typical status message
would be “6.5 Hours Battery Runtime”.

• The battery life indicator is continuously being updated. If the current draw from the battery increases—as when the
outputs are switched on—the runtime indicator recalculates the battery life.

• The second light reports on the battery’s charging status, either “Charging” or “Not Charging.” The battery only charges
when there is a need and the charger is connected. The fact that the charger is connected does not necessarily mean that
the battery is charging.

• The third light indicates whether the charger is connected. When the External DC light is on, the charger is connected and
powering the meter. The charger may or may not also be charging the battery, depending on the battery status.

• The fourth light is the Cycle counter and indicates the number of charging cycles the battery has undergone.

• Check the Disable Charging box when the meter is going to run on AC power for a long time. The Disable Charging
feature prevents the battery from generating excessive heat. In some cases, a lower level of noise is realized.

The graphs to the right of the battery status indicator show the present temperature of the battery and the percentage of
charge the battery currently holds.

Auto Shutdown

The meter has a feature to help prevent the flow meter from operating in a low battery range. Any time the flow meter battery
goes below 5% charge, the user is prompted to plug in the charger. The meter will automatically shut down if the charger is
not plugged in within 120 seconds.

PC Page

Figure 99: System PC

PC CPU STATUS

The status graph shows the temperature of the system processor board and the CPU (Central Processing Unit), the
percentages of RAM (Random Access Memory) used and how busy the CPU is.

Backlight Control

The System > PC page contains the backlight brightness control and the switch for the automatic screen saver. Judicious use
of these controls help extend the battery life between charges. The flow meter’s WVGA screen consumes about 1/3 of the
battery capacity when the meter is running on battery. By using the screen saver and lowering the amount of backlight when
conditions permit, battery life is significantly extended for that session.

• The backlight Brightness control ranges from a low of 1 (least bright) to 5 (brightest).

• The Timed Power Off box, when checked, enables the screen saver to start after the time indicated in Off Minutes. Tap the
display to turn it back on..

• The Off Minutes has a range of 0…50 minutes.

If the meter is running with the battery charger connected, there is no need to either decrease the backlight or use the screen
saver function.

Table 21: Modbus data formats

Modbus Register / Word Ordering

Each Modbus Holding Register represents a 16-bit integer value (2 bytes). The official Modbus standard defines Modbus as a
‘big-endian’ protocol where the most significant byte of a 16-bit value is sent before the least significant byte. For example,
the 16-bit hex value of ‘1234’ is transferred as ‘12’ ‘34’.

Beyond 16-bit values, the protocol itself does not specify how 32-bit (or larger) numbers that span over multiple registers
should be handled It is very common to transfer 32-bit values as pairs of two consecutive 16-bit registers in little-endian word
order. For example, the 32-bit hex value of ‘12345678’ is transferred as ‘56’ ‘78’ ‘12’ ‘34’. Notice the Register Bytes are still sent in
big-endian order per the Modbus protocol, but the Registers are sent in little-endian order.

Other manufacturers store and transfer the Modbus Registers in big-endian word order. For example, the 32-bit hex value of
‘12345678’ is transferred as ‘12’ ‘34’ ‘56’ ‘78’. It does not matter in which order the words are sent, as long as the receiving device
knows which way to expect it.

Since it is a common problem between devices regarding word order, many Modbus master devices have a configuration
setting for interpreting data (over multiple registers) as ‘little-endian’ or ‘big-endian’ word order. This is also referred to as
swapped or word-swapped values and allows the master device to work with slave devices from different manufacturers.

If, however, the endianness is not a configurable option within the Modbus master device, it is important to make sure it
matches the slave endianess for proper data interpretation. The transmitter actually provides two Modbus Register maps to
accommodate both formats. This is useful in applications where the Modbus Master cannot be configured for endianness.

Operation

ModbusTCP allows users the ability to monitor basic parameters such as flow and totals via the Ethernet port. The DXN
ModbusTCP operation is automatic, and starts up automatically. Errors may be cleared with some settings changes and
disabling/enabling Modbus TCP server. During setup, system error boxes may pop up indicating network conflicts.

• Server Active indicator is bright green when operating properly.

• Network Connected is bright green when network is connected properly.

• No Network Connection will appear with a dull green box if there is no Ethernet connection.

• Activity will flash upon successful read of Modbus Registers.

• Error will flash upon improper reads/writes, or incorrect Modbus addressing.

First, set up the Ethernet settings that will be used to monitor the flow meter:

1. Make sure to unplug the Ethernet cable.

2. Navigate to System > ENet.

3. Verify the Enable Modbus TCP Server box is unchecked. If checked, press the box to disable the Modbus TCP server.

Inputs/Outputs

Rate Pulse Scaling

The rate pulse has a maximum frequency of 1000 Hz that is proportional to the minimum and maximum user flow rates
entered. Setting the minimum and maximum flow rates is accomplished using the Meter > Limit software controls.

For example, if the minimum flow rate were set to –100 gpm and the maximum flow rate was +100 gpm the 1000 Hz output
would span the distance from –100…100 gpm.

In this example the output frequency would then be interpreted as follows:

0 Hz = –100 gpm

250 Hz = –50 gpm

500 Hz = 0 gpm

750 Hz = +50 gpm

1000 Hz = +100 gpm

The maximum current capacity for the transistor is 100 mA with a maximum supply voltage of 10V DC. These parameters
require the pull-up resistor rated for a minimum of 1000 ohms.

In rate pulse output mode, the transistor has a duty cycle of 50%.

Totalizing Pulse

When used to transmit a totalizing pulse, the digital output sends a fixed width (33 mS) pulse that follows the display totalizer.
For each increment of the totalizer, the digital output sends 1 pulse. The duration of the pulse is 33 mS with an amplitude
approximately equal to the level of +V. See “Totalizer Page” on page52 to set totalizer parameters.

OTE:N The totalizing pulse output can be set for total net, total positive, total negative, total Doppler, energy net, energy

positive and energy negative.

The 4…20 mA output interfaces with most recording and logging systems by transmitting an analog current signal that is
proportional to system flow rate. The 4…20 mA output is internally powered (current sourcing) and can span negative to
positive flow/energy rates.

The 4…20 mA output is driven from a +15V DC source located within the meter. The source is isolated from earth
ground connections within the DXN. The 4…20 mA output signal is available between the 4…20 mA Out and Signal

KFactors

KFACTORS

Description

The Kfactor (with regards to flow) is the number of pulses that must be accumulated to equal a particular volume of fluid. 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 one 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 flow rate. The same Kfactor number,
with a time frame added, can be converted into a flow rate. If you accumulated 1000 counts (one gallon) in one minute, then
your flow rate would be one gpm. The output frequency, in Hz, is found simply by dividing the number of counts (1000) by
the number of seconds in a minute (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 one gpm. If the frequency counter registered 33.333 Hz (2 × 16.666 Hz), then the flow rate would be
two gpm.

Finally, if the flow rate is two gpm, then the accumulation of 1000 counts would take place in 30 seconds because the flow
rate, and hence the speed that the 1000 counts is accumulated, is twice as great.

Calculating KFactors

Many styles of flow meters are capable of measuring flow in a wide range of pipe sizes. Because the pipe size and volumetric
units the flow meter will be used on vary, it may not possible to provide a discrete Kfactor. In the event that a discrete Kfactor
is not supplied then the velocity range of the flow meter is usually provided along with a maximum frequency output.

The most basic Kfactor calculation requires that an accurate flow rate and the output frequency associated with that flow
rate be known.

Example 1

Known values are:

Frequency = 700 Hz

Flow Rate = 48 gpm

700 Hz × 60 sec = 42,000 pulses per min

K factor

Example 2

Known values are:

Full Scale Flow Rate = 85 gpm

Full Scale Output Frequency = 650 Hz

650 Hz × 60 sec = 39,000 pulses per min

K factor

The calculation is a little more complex if velocity is used because you first must convert the velocity into a volumetric flow
rate to be able to compute a Kfactor.

To convert a velocity into a volumetric flow, the velocity measurement and an accurate measurement of the inside diameter
of the pipe must be known. Also needed is the fact that one 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.

So for every foot of fluid travel 0.384 gallons will pass.

What is the flow 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 flow rate is known, all that is needed is an output frequency to determine the Kfactor.

Known values are:

Frequency = 700 Hz (By measurement)

Flow Rate = 99.1 gpm (By calculation)

700 Hz × 60 sec = 42,000 pulses per gallon
