WELCOME TO THE ECHOSONIC® QUICK START
The EchoSonic® quick start is meant to show some of the more common setup solutions to getting the
EchoSonic® 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® Manual or refer to the
Flowline website at flowline.com.
WE DO YOUR LEVEL BEST
Thank you for purchasing Flowline’s EchoSonic®. This general purpose ultrasonic sensor provides non-contact
detection up to 9.8’ (3m) 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® documentation located at
flowline.com.
COMPONENTS
Depending on how the sensor model that was shipped, you should have the EchoSonic® and Viton® gasket
which are required to install the EchoSonic®. Some models will have the USB® Key Fob (LI99-2001) included
with the EchoSonic®. Other will require the separate purchase of the Fob. A LI99-2001 Fob is required to
interface to WebCal® and configure the sensor.

CONFIGURING THE ECHOSONIC®
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/webcal-software onto a PC with the following minimum
specifications:
Windows® XP/Vista/7/8/10, 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 EchoSonic® 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 EchoSonic® 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.
NOTE: EchoSonic® II ships with the LI99-2001 Fob (white in color). The LI99-1001 Fob (black in color)
can be used with EchoSonic® II (LU27 series) to configure the sensor with WebCal®.

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.
 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
EchoSonic® starts up, this describes the level at which it will begin
searching for the contents of the tank.
NOTE: If you would like to start over, click the Clear Screen button on the
right.
A New feature of WebCal® 6.0 is the ability to configure the sensor in volumetric units (Gallons or Liters) or in
