Thank you for purchasing the EchoSonic ® II. This general purpose ultrasonic sensor
provides non-contact detection powered by the 4-20 mA loop. This Quick Start
includes everything you’ll need to get the sensor up and running. For complete
information, please refer to EchoSonic ® II documentation located at
www.flowline.com.
Components
Depending on how the sensor was shipped to you, you may or may not have the
components shown below. All three components, including the sensor, USB Fob, and
Viton® gasket are required to configure and install the sensor. If you need any
additional components, you can order them directly from Flowline.
General notes for electrical connections, usage and safety:
 Where personal safety or significant property damage can occur due to a
spill, the installation must have a redundant backup safety system installed
 Wiring should always be completed by a licensed electrician
 Supply voltage should never exceed 28 VDC
 Protect the sensor from excessive electrical spikes by isolating the
power whenever possible
 The sensor materials must be chemically compatible with the liquids
to be measured
 Design a fail-safe system for possible sensor and/or power failure
 Never use the sensor in environments classified as Hazardous
Welcome to the EchoSonic®II Quick Start
The EchoSonic ® II Quick Start is meant to show some of the more common
setup solutions to getting the sensor up and running quickly. If you run into an
issue that is not addressed here or wish to install or set up with a non-standard
configuration, please address the EchoSonic ® II Manual or refer to the Flowline
website at www.flowline.com.

Wiring the Sensor
After mounting the sensor, make the necessary electrical connections. A wiring
diagram with specific recommendations for the sensor’s configuration can be printed
from the WebCal program. A general wiring diagram is shown on the previous page.
Red and Black leads are for connection to a 24 VDC power supply or to a 4-
20 mA loop power source. The red and black wires can be extended more
than 1000 feet using 22 gauge or larger wire, however do not extend the
green and white wires.
White and Green leads are reserved for use with WebCal and should not be
connected during usage in the application. These wires should not be
connected to WebCal while power is supplied from any source other than the
LI99 FOB.
Shield. This common wire provides transmission protection.
Never allow the white or green wires to touch any power supply.
Configuring the Sensor
Configuration of your sensor should be performed prior to mounting, since it requires
connection to your PC.
Step 1: Install the WebCal Software
Download WebCal from www.flowline.com onto a PC with the following minimum
specifications:
Windows® 2000/XP/Vista/7, 10 MB storage space, 256 MB RAM, 1 USB 2.0 port
Double-click the WebCal icon to install before proceeding to Step 2. You must have
an active Internet connection to install WebCal, as it will automatically verify driver
updates.
Step 2: Connect the USB Fob
NOTE: Do not connect the Fob until after you’ve installed WebCal.
The sensor communicates to its configuration software through the USB Fob. Prior to
connecting the Fob, ensure that all external power is disconnected from the sensor as
power is provided through the PC’s USB 2.0 port. Do not use a cable connecting the
sensor to the Fob any longer than 15 feet.
1) Connect the red, green, white, and black wires from the sensor to the
corresponding colored terminals on the Fob (as shown in the diagram).
2) Tighten the terminal screws with a slotted screwdriver.
3) Plug the Fob into your PC’s USB port.

Step 3: Configure through WebCal
These instructions will walk you through configuration of the sensor through
WebCal. For more information, click the WebCal HELP button in the lower
right corner or anywhere on the WebCal screen or refer to the sensor Manual
found at www.flowline.com.
Using a Standpipe
A standpipe may be used to dampen turbulence, separate surface foam from the
point of measurement or increase performance in heavy vapor. Select a 3” pipe (a
2” pipe is usable, but the minimum) and attach the sensor with a coupling and
reducer bushing. 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. Cut the bottom end of the pipe at 45° and drill a
1/4”pressure equalization hole high in the dead band. The pumps should not
drive liquid past the open end of the standpipe which causes the liquid in the
pipe to become turbulent.

Configuration Settings
Mounting the Sensor
The sensor should always be mounted perpendicular to the liquid surface using the
provided Viton® mounting gasket. Insure that there are no restrictions or obstacles in
the path of the ultrasonic signal. Always use fittings with thin wall mounting structures
that isolate the transducer. This will provide the best performance over the lifetime of
the product. Further mounting information can be found on the Flowline website at
www.flowline.com. An instructional video on is also available on the website.
The LU27 has a 1” NPT or G fitting and requires more care in mounting to reduce any
coupling of the ultrasonic signal to the mounting structure. The following fittings are
recommended:
For installations in existing 2” fittings:
1) Use LM52-1400 2” Thread x 1” Thread adapter. (An
Adapter with an air gap around the 1 inch threads as
shown is recommended)
For installations in plastic tanks:
1) Use a Bulkhead fitting LM52-1890 1” inch Bulkhead
fitting,
2) Use a Bulkhead fitting LM52-2890 in combination with
LM52-1400 or,
3) Weld a plastic 1” half coupler to the tank’s top.
For installations in metal tanks:
1) Use the recommended bulkhead fittings as shown
above or a LM52-1850 1” Flange. The flange fitting
must have a riser for the threaded section. Do not drill
or tape a blind flange.
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 coupler is tightly wrapped in vinyl tape to dampen
vibrations.
For installations in open tanks and sumps:
1) Use Flowline's LM50-1001-1 side mount bracket,
which includes a 2" x 1" thread reducer bushing.
Using the drop-down menus on the left of the WebCal screen, set the configuration
for your application requirements. When a selection does not apply to your
application, “Not Applicable” will appear in the drop-down. Make sure all drop-downs
are set appropriately for your application before moving to the Tank Level section.
NOTE: If you would like to start over, click the
Clear Screen button on the right.
Enter the appropriate tank level set points for your application.
Tank Level Settings
 Units. Display measurements in inches
or centimeters.
 Sensor Height. Distance measured from
the bottom of the empty tank to the
bottom of the transducer. Under factory
configuration, this becomes the 4 mA set
point.
 Fill Height. Distance measured from the
bottom of the empty tank to the maximum
fill height within the tank. Under factory
configuration, this becomes the 20 mA
set point.
 Loop Fail Safe. Use this setting to
choose the output level should the sensor
not receive an echo.
 Output at Empty. Use this setting to
change the 4-20 mA setting from its
default.
 Startup Condition. During the 15-20
seconds during which the sensor starts
up, this describes the level at which it will
begin searching for the contents of the
tank.

configuration.
The Advanced button is used for options available when setting up the sensor with
special, non-standard features. Many of these features are available for specific
applications that may change from time to time. Consult WebCal's HELP file for the
latest information on the use of any of these features.
The more commonly used Advanced features are the Invert Relay and Increase
Output Filtering described below.
Before configuration can be completed:
You must click the Write to Unit button to save the settings to the unit.
Then, click Wiring Diagram for a hard copy of the sensor settings.
Finally, enter the file name under which you wish to save the configuration
file and click Save Config File.
Configuration is now complete.
For Updates to WebCal, or to make sure you’re using the most up-to-date
version available, click the Update tab on the top of the WebCal screen.
To view the Demo page (shown here), click the Demo tab on the top of the WebCal
screen.
The demo page is a simulation,
useful for verifying the
configuration. There is not
enough power going to the unit to
power the relays. The larger
numbers represent the liquid
level while the smaller numbers
show the distance from the
transducer to the surface. The
senor must be pointed at a flat
perpendicular surface.
