C. Conduit Enclosure: The conduit enclosure (-51_1) has a flip
cover with two 1/2” NPT female conduit ports and an internal terminal
strip for wiring. To open the enclosure, you will need a small insertion tool
such as a small screwdriver or paperclip. Insert the tool into the hole locat-
ed at the front of the enclosure and gently push on the latching mechanism
to release the cover. Rotate the hinged cover up for 135° access to the ter-
minal strip. Before closing the enclosure, make sure that the enclosure
gasket is properly seated, and that any conduit fittings, cable connec-
tors and/or plugs are installed correctly and sealed.

About this Manual: PLEASE READ THE ENTIRE MANU-
AL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on the LU05-5__1, LU11-5__1,
LU12-5__1 and LU13-5__1 Ultrasonic Level Transmitter from
FLOWLINE. Please refer to the part number located on the trans-
mitter label to verify the exact model configuration which you have
purchased.
User’s Responsibility for Safety: FLOWLINE manufac-
tures a broad range of level sensing technologies. While each of
these sensors is designed to operate in a wide variety of applica-
tions, it is the user’s responsibility to select a sensor model that is
appropriate for the application, install it properly, perform tests of
the installed system, and maintain all components. The failure to do
so could result in property damage or serious injury.
Proper Installation and Handling: Only properly trained
staff should install and/or repair this product. Install the transmitter
with the Viton gasket and never overtighten the transmitter within
the fitting. Always check for leaks prior to system start-up.
Wiring and Electrical: A supply voltage of 12-28 VDC is
used to power the transmitter. The sensor circuit should never
exceed a maximum of 28 volts DC. Electrical wiring of the sensor
should be performed in accordance with all applicable national,
state, and local codes.
Material Compatibility: The LU__-5__1 enclosure is made
of a flame retardant Polycarbonate (PC/ABS FR). The transducer is
made of Polyvinylidene Fluoride (PVDF). Make sure that the
model which you have selected is chemically compatible with the
application media.
Enclosure: While the transmitter housing is liquid-resistant the
LU__-5 __1 is not designed to be operational when immersed. It
should be mounted in such a way that the enclosure and transduc-
er do not come into contact with the application media under nor-
mal operational conditions.
Make a Fail-Safe System: Design a fail-safe system that
accommodates the possibility of transmitter and/or power failure.
FLOWLINE recommends the use of redundant backup systems
and alarms in addition to the primary system.
Flammable, Explosive or Hazardous Applications:
The LU__-5__1 should not be used within classified hazardous
environments.
Warning
Always use the Viton gasket when installing the LU1_-5_ _1
transmitter, and always connect the shield wire to the com-
mon ground.

Step Four
PREPARATION
A. Supply Voltage: The transmitter power supply voltage should
never exceed a maximum of 28 VDC. Flowline controllers and meters
have built-in 24 VDC power supplies for use with the transmitter.
Alternative controllers and/or power supplies with a minimum output
may also be used with the transmitter for calibration and/or operation.
B. Cable Length: The cable length may be extended up to a max-
imum of 1000 feet between the transmitter and its point of termina-
tion, using a well-insulated, shielded wire from 14 to 18 gauge.
C. Wire Stripping: Models LU__-50_1 with cable connections
are provided with a 10’ cable. If necessary, use a 10 gauge wire strip-
per and carefully remove the outer layer of polypropylene insulation
from the last 1-1/4” of the transmitters cable. Unwrap and discard the
exposed foil shield from around the signal wires. With a 20 gauge
wire stripper, remove the last 1/4” of the colored insulation from the
signal wires.
D. Factory Span: Models LU05-5_ _1,
LU11-5_ _1, LU12-5_ _1, LU13-5_ _1 are
factory calibrated with 4 mA at their maxi-
mum range (tank empty) and 20 mA (tank
full) at their minimum range values. The 4
and 20 mAspan set points can be reverse cal-
ibrated on all models.
E. Maximum Applied Range: The Individual or cumulative
effects of agitation, vapor or foam can reduce the overall quality of
signal return and shorten the maximum applied range of the transmit-
ter. To determine the maximum applied range of the transmitter in
your application, refer to the below derating chart.

Vapor = 4-6 @ 100 kHz Vapor = 3-5 @ 50 kHz
Foam = 5-6 @ 100 kHz Foam = 4-6 @ 50 kHz
A. Factory Settings: One option for calibration is to use the
factory setting of the EchoSonic. Each version of EchoSonic has a
preset 4mA and 20 mA as seen below:
Due to advances in the electronics with the Digital Infinity transmit-
ters, any resolution improvements are negligible when decreasing the
overall operational range of the transmitter.
Flowline recommends using the original factory settings with the
transmitter and making the range adjustments in the local panel meter,
display or PLC system.
B. Distance to Current Charts: Below are charts for each
version of EchoSonic. The charts indicate the current at specific dis-
tances away from the transmitter. To located the current equivalent to
an empty /full tank, follow the instructions below:
1. Measure the distance from the bottom of the sensor to the bottom
of the tank.
2. Locate this value under distance column for the transmitter ver-
sion.
3. Select the corresponding current value from the chart. Distances
not listed can be extrapolated from the next highest and lowest
distances.
4. Repeat the same steps for the full tank setting.
C. Display Adjustments: Typical panel meters and displays
use a 2-point method for calibration, based upon empty and full set-
tings. Each setting will have a current reading and a corresponding
value that appears on the display at that current. For example, 4 mA
= 0.0 and 20.0 mA= 100.0 is a common setting. This represents a dis-
play of 0 when 4mA is applied to the sensor and 100.0 when 20 mA
is applied to the sensor.
The same can be accomplished using the factory setting of the
EchoSonic. For example, a LU05-5__1 transmitter will output 8.2
mA when the level is 36” away form the transmitter (from chart). If
the sensor is installed on a 36” tall tank, then the current output when
the tank is empty will be 8.2 mA. When programming the display,
entering 8.2 mA= 0.0 and 20.0 mA = 100.0 will have the display read
between 0 to 100. This will have the resolution as calibrating the
LU05-5__1 to 4mA = 36.0 and 20mA = 2.0 and the display pro-
grammed to 4mA = 0.0 and 20 mA = 100.0. This method avoids hav-
ing to calibrate the sensor and will have no effect with respect to the
resolution of the unit.

CALIBRATION
H. Target Calibration - Setting 4 mA or 20 mA: The sec-
ond option for calibrating the EchoSonic is to change the 4mA from
the factory setting to the empty tank and the 20 mA from the factory
setting to the full tank. This method will require that the level of liq-
uid be lowered to the empty level and raised to the full level. If this
is not possible, the changes can be accomplished by pointing the
transmitter at a wall or flat object the equivalent distances for empty
and full. This method is referred to as Target Calibration.
I. Calibration Tools: To target calibrate the transmitters 4-20 mA
span you will need a 12-28 VDC power supply, tape measurer, flat
reflective target such as a wall, optional multimeter and Flowline box
insert for use as a product holder.
J. Off Tank Target Calibration: Locate a flat reflective cali-
bration target such as a wall. Place the transmitter perpendicular to the
target in the provided Flowline box insert or equivalent holder.
Alternatively, you may hold the transmitter with your hand, but
it is critical that the product is held steady and perpendicular to
the target during span calibration.

K. 4 mA Span Calibration Procedure (Tank Empty)
1. If the transmitter is wired with power ON, turn power OFF to the
transmitter and wait 30 seconds before continuing.
2. Connect the the Red transmitter wire to the (+) terminal of the
power supply. Connect the Black and White transmitter wires to
the (-) terminal of the power supply.
3. Stretch the tape measurer out to the appropriate distance in
between the transmitter and target.
4. Position the transmitter at the desired 4 mA calibration distance
defined as the air gap space between the transducer and the target.
Make sure that the transmitter is stationary and perpendicu-
lar to the target before continuing.
5. To calibrate the set point, turn power ON to the transmitter and
wait for the LED to flash indicating that the set point has been
accepted. Depending upon the span, this can take up to 45 sec-
onds. If the LED does not flash within 60 seconds, check to make
sure that line power is at least 14 VDC and that the transmitter and
target are both stationary and perpendicular.
6. Turn power OFF to the transmitter and disconnect the White
transmitter wire from (-) terminal of the power supply, leaving the
Black transmitter wire attached.
7. Continue ahead to the 20 mA span calibration procedure.

CALIBRATION
L. 20 mA Span Calibration Procedure (Tank Full)
1. If the transmitter is wired with power ON, turn power OFF to the
transmitter and wait 30 seconds before continuing.
2. Connect the the Black transmitter wire to the (-) terminal of the
power supply. Connect the Red and White transmitter wires to the
(+) terminal of the power supply.
3. Stretch the tape measurer out to the appropriate distance in
between the transmitter and target.
4. Position the transmitter at the desired 20 mA calibration distance
defined as the air gap space between the transducer and the target.
If the transmitter is installed in a flange fitting with riser, then
the 20 mAcalibration distance should be no less than the riser
height + half the transmitter’s dead band specification (ie: 4”
riser + 8” dead band = 8” minimum 20 mA calibration dis-
tance). Make sure that the transmitter is stationary and per-
pendicular to the target before continuing.
5. To calibrate the set point, turn power ON to the transmitter and
wait for the LED to flash indicating that the set point has been
accepted. Depending upon the span, this can take up to 10 sec-
onds. If the LED does not flash within 30 seconds, check to make
sure that line power is at least 12 VDC and that the transmitter and
target are both stationary and perpendicular.
6. Turn power OFF to the transmitter and disconnect the White
transmitter wire from (+) terminal of the power supply, leaving
the Red transmitter wire attached.
7. The 4-20 mA span calibration is now complete.

M. On Tank Target Calibration: Alternatively, the transmit-
ter’s 4-20 mA span may be target calibrated installed ON the tank by
raising or lowering the liquid level to the desired 4 mA (tank empty)
and 20 mA(tank full) span distances. To do so, follow the above steps
#8-K and #9-M calibration procedure with the exception of moving
the liquid level (versus the transmitter) in steps #8-K-4 and #9-M-4.
During calibration, make sure that the liquid is still and that there
is at least some liquid in the tank for the 4 mA (tank empty) set
point.

2. Riser: Installations with tall, narrow risers can impede the
acoustic signal. Select a fitting with the right riser height versus
inner diameter geometry.
3. Flange: If installing on a flange, select a flange with a thread that
is above the plane of the flange, such as the Spears 2” One Piece
Flange (series 852-020). Avoid the use of blind flanges with tapped
threads or flanges where the threads are even with the plane of the
flange, such as the Banjo 2" Poly ANSI Flange (series AF200).
If the installation requires the use of a
blind flange, tap a thread 1” larger than
the sensors thread and add a Reducer
Bushing such as a Spears thread x
thread Reducer Bushing [series 839-
338 (3”x2”) for LU11 and LU13 ver-
sions or series 839-249 (2”x1”) for
LU05 and LU12 versions].
4. Side Mount Bracket: The LM50-1001
side mount bracket or equivalent can be used
for open tank top installations against the
side wall. For the LU05 and LU12 versions,
order the LM50-1001-1, which includes a 2”
x 1” Reducer Bushing.
5. Stand Pipe: A stand pipe may
be used to dampen turbulence.
Flowline recommends using a
stand pipe when foam is pre-
sent in the application. Select
a 2” pipe for the LU05 or LU12
Versions and a 3” pipe for all
other models. The pipe length
should run the measurement
span. Cut a 45° notch at the bot-
tom of the pipe and drill a 1/4”
pressure equalization hole high
in the dead band.
Step Ten
INSTALLATION
A. Fitting Selection: Check the transmitter
part number to determine the required fitting mount
size and thread type. The transmitter is commonly
installed in tank adapters, flanges, brackets or stand
pipes. Note: Always include the gasket when
installing the EchoSonic.
1. Tank Adapter: Select a tank adapter fitting
with minimal height so as to ensure that the
installed transducer will not be substantially ele-
vated into the fitting such as the Hayward 2”
Tank Adapter (socket by thread). For the LU05-
5__1 and LU12-5__1 versions, add a Reducer
Bushing such as the Spears 2” x 1”, thread x thread, Reducer
Bushing (series 839-249, Flowline p/n LM52-1001). Avoid tank
adapter (thread x thread) styles and/or pipe stops forward of the
installed transducer.

A. LED Status: During normal operation, the
transmitter LED will be OFF and the 4-20 mA
current will proportionately indicate level within
the span. The following are the three LED diag-
nostic modes for troubleshooting:
1. Solid LED: Indicates that the transmitter
cannot identify the level. The current will
hold at 22 mA until such time that the level is
acquired. Check the installation (fitting,
obstructions), application (level, foam, agita-
tion, vapor) and transmitter (coating build-up
or extreme condensation on transducer).
2. Continuously Flashing LED: Indicates
that the level is outside of the transmitter’s
calibrated span and/or range. Check the level
and recalibrate the span if required.
3. Three Quick LED Flashed at Power Up: Indicates that the
transmitter is installed in a challenging installation fitting that
may interfere with optimum acoustic signal transmission and/or
receipt. The level should be more than 2’ away from the trans-
ducer for valid feedback. See installation section and check to
ensure that the transmitter is installed appropriately.
B. Testing the Transmitter
1. Connect a multimeter in series
with the black wire to read the
current output.
2. Verify that the current increas-
es (tank filling) and decreases
(tank emptying) appropriately
in the calibrated span.
3. If not, carefully observe and
attempt to correlate any instal-
lation, level or application
event for more specific trou-
bleshooting direction.
