Installation Step Seven
1. Do not mount the sensor at an angle.
2. Liquid should never enter the dead band.
3. Side Wall:
a. Mount the sensor at least 3” from the side wall.
b. LU27 Series - Mount at least 2” from the side
wall.
4. Do not mount where obstacles will intrude on sensor’s
beam width.
a. LU27 Series - Mount at least 2” from the side
wall.
b. LU23, LU28 & LU29 Series - Mount at least 3”
from the side wall.
5. Do not mount the sensor in a vacuum.
6. Avoid mounting in the center of a dome top tank.
7. In cone bottom tank, position the sensor over the
deepest part of the tank.
INSTALLATION IN EXISTING FITTINGS
If the existing fitting is larger than the threads of the
EchoSonic®, select a reducer bushing such as the LM521400 (2” thread x 1” thread) or LM52-2400 (3” thread x 2”
thread).
LM52-1400
LM52-2400
Do not install at
angle relative to the
liquid.
Do not install within
3” of tank sidewall.
Do not install with
objects in the
beam.
Do not install in
applications with
vacuum.
The EchoSonic® should always be mounted perpendicular to the liquid surface and installed using the provided
Viton mounting gasket. Make sure that the fitting and transmitter threads are not damaged or worn. Always
hand-tighten the transmitter within the fitting. Perform an installed leak test under normal process conditions
prior to system start up. Note: The preferred mounting fitting for the LU27 series is the LM52-1400 (2”
thread x 1” thread) reducer bushing.
MOUNTING GUIDE
METAL TANKS (LU27 SERIES ONLY)
The LU27 series has been optimized for use in non-metallic fittings.
1. For best performance, avoid the use of metallic fittings.
a. Use a plastic 2” x 1” reducer bushing, such as the LM52-1400 or a plastic 1” flange, such as the
LM52-1850 for metallic tanks.
2. While installations directly into a 1” metal fitting are not recommended, acceptable results may be
obtained if the 1” fitting is a half coupling in form and the outer diameter of the coupling is tightly
wrapped in vinyl tape to dampen vibrations.

exceeds the dimensions listed in
the Riser Specifications chart.
Use a larger tank adapter which
takes into account the Riser
Specifications.
FITTING SELECTION
Check the part number to determine the required fitting mount size and thread type. EchoSonic® is commonly
installed in tank adapters, flanges, brackets or standpipes. Note: Always include the gasket when installing the
EchoSonic®.
1. Tank Adapter: Select a tank adapter fitting, such as the LM52-1890 for the LU27 series or the LM522890 for the LU23, LU28 & LU29 series.
a. For best results, select a 2” tank adapter and add a reducer bushing such as the LM52-1400,
thread x thread, reducer bushing.
b. Avoid tank adapter (thread x thread) styles and/or pipe stops forward of the installed transducer.
c. Always mount the tank adapter so the majority of fitting is outside the tank.
i. Note: Never mount the tank adapter upside down or where the bulk of the material is
inside the tank.
2. Riser: Installations with tall, narrow risers can impede the acoustic signal.
a. Core Out Concrete: Applications where tank with a concrete ceiling that has been cored out
can also be considered as a riser type application. In these applications follow a 2:1 ratio (Inner
Diameter to Core Height) for the diameter of the core.
a. LU23, LU28 & LU29 Series: 2” (5 cm) diameter risers should be no taller than 5” (12.7 cm).
Larger diameter risers should be no taller than 12” (30.5 cm).
b. LU27 Series:

Flange (LU27 series): If installing on a flange, select a flange with a thread that is above the plane of the
flange, such as the LM52-1850.
a. The LU23, LU28 & LU29 series works well with Flange installations.
b. 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 1" Poly ANSI Flange (series AF100).
c. Use a flange with a 2” thread and add a 2” to 1” reducer bushing to complete the installation for
the LU27 series.
3. Side Mount Bracket: For installations in open tanks and sumps, use the LM50 series side mount
bracket.
a. For the LU27 series, order the LM50-1001-1, which includes a 2”x 1” Reducer Bushing.
b. For the LU23, LU28 & LU29, series, order the LM50-1001 side mount bracket.
Note: The Side Mount Bracket (LM50 series) is not designed for use with stand pipes or as a method
to secure stand pipes. There are too few threads to properly hold the sensor and the stand pipe.

Installation Step Seven
a. Pipe can be made of any material.
b. Minimum ID for the stand pipe is listed below.
i. A 2” pipe (min. pipe ID) is usable with the LU27
series.
ii. A 3” pipe (min. pipe ID) is usable with the LU23,
LU28 & LU29 series.
iii. Pipes larger than 3” can also be used.
c. Use a coupling and reducer bushing to attach the
EchoSonic® to the pipe.
i. With the LU27 series, be sure to use a plastic
reducing bushing such as LM52-1400 2” T x 1” T
fitting or the LM52-1410 2” S x 1” T fitting.
ii. For the LU27 series, be sure to use a plastic
reducing bushing such as LM52-1400 (2”T x 1”T)
fitting or the LM52-1410 (2”S x 1”T) fitting.
iii. For the LU23, LU28 & LU29 series, use a reducer
bushing such as LM52-2400 (3”T x 2”T) fitting or
the LM52-2410 (3”S x 2”T) fitting.
d. The pipe length should run the measurement span and
the bottom of the pipe should remain submerged at all
times to prevent foam from entering the pipe.
e. Cut a 45°notch at the bottom of the pipe and drill a
1/4”pressure equalization hole in the dead band.
f. The pumps should not drive liquid past the open end of
the stand pipe which causes the liquid in the pipe to
oscillate.

TESTING THE TRANSMITTER
1. Connect a multimeter in series with the black wire to read the current output.
2. Verify that the current increases (tank filling) and decreases (tank emptying) appropriately in the
calibrated span.
3. If not, carefully observe and attempt to correlate any installation, level or application event for more
specific troubleshooting direction.

PROBLEM
SOLUTION
Transmitter indicates a
current of 0 mA.
Check the EchoSonic® wiring for an open circuit. An open circuit is the
most common issue with a 0 mA signal.
Transmitter jumps to a
current reading between
19 and 20 mA.
Check the EchoSonic® installation. Bad installation fittings will cause
false signals near the top of the tank, which typically translates to a
signal between 19 and 20 mA. Also look for interference just below the
transmitter. If the transmitter is installed in a metal fitting, switch to a
plastic fitting.
Transmitter indicates a
current over 23 mA.
Check the wiring for a short circuit. The EchoSonic® is current limited
to 22 mA. Anything above 22 mA indicates a short circuit.
Transmitter always jumps
to LOST condition
Check the dimensional configuration (Sensor Height and Fill-Height)
of the EchoSonic®. Make sure that the Fill-H setting corresponds to
the full level of liquid (from the bottom up) and not the distance from the
transmitter to the liquid (top down).
Output of transmitter is
opposite of the level of
liquid.
Check the Output at Empty Setting.
No Unit Detected in
WebCal®.
WebCal® cannot detect an EchoSonic® connected to the computer.
Check that the Fob is connected to the USB® port.
Check that all four wires (Red, Black, White and Green) are
securely attached to the Fob.
Check in Device Manager that both drivers (WebCal
®
Configuration & EchoFob) are present.
Internet error. The server
name or address could not
be resolved.
This is a warning indicating the computer configuring EchoSonic® is not
connected to the internet. Click OK to continue. Flowline recommends
being connecting to the internet for all configurations. Not being
connected to the internet will not prevent the EchoSonic® from being
configured.

the features in
Configuration.
As choices are made in Configuration, WebCal® will begin to eliminate
functions that are not applicable to a configuration. To reset
Configuration or get access to all the features, click on the Clear
