WebCal Step 1: Configuration
This section of WebCal is where you select the application’s configuration settings. Start from the top and
work to the bottom, choosing the selections that are applicable to your configuration. “Not Applicable”
will automatically show when a selection doesn’t apply to your configuration settings, and you may move
on. All configuration settings must be selected or have “Not Applicable” before you can continue to step
2. Note: Pressing the Clear Screen button will reset the configuration table and allow access to all of the
features.
Loop Fail-Safe
This feature allows you to select the fail-safe current output if the sensor
fails to detect a return signal (LOST). When the sensor regains signal,
the output current will revert back to the current level condition.
o Hold Last Value - The output will remain in the same state as
the last echo detected. Example: If the output was 6.7 mA just
prior to the LOST signal, the device will continue to output 6.7
mA. When the sensor regains signal, the output will indicate the
level when the signal was regain.
o Empty - The output will revert to the current value of an Empty
tank. The empty state is dependent upon the Output at Empty
setting. When 4 mA at Bottom is selected, the sensor will output
4 mA when a fail-safe condition occurs. If 20 mA at Bottom is
selected, the sensor will output 20 mA when a fail-safe condition
occurs
o Full - The output will revert to the current value of a Full tank.
The full state is dependent upon the Output at Empty setting.
When 4 mA at Bottom is selected, the sensor will output 20 mA
when a fail-safe condition occurs. If 20 mA at Bottom is
selected, the sensor will output 4 mA when a fail-safe condition
occurs
o Overfill (21mA) - The output current will go to 21mA when the
return signal is lost.
o Overfill (22mA) - The output current will go to 22mA when the
return signal is lost.
Note: Right click on any menu that you may have questions on to open the help menu.
Note: To reset, press the Clear Screen button.

Output at Empty
This feature allows you to select the orientation of the 4 to 20mA output
(4 to 20 mA or 20 to 4 mA). Choose which output setting best fits the
application. Typical installations are set with 4 mA at Bottom. This will
not affect the performance of the sensor other than the output of the
EchoSonic II. WebCal’s factory default is 4mA at bottom and 20mA at
top. When connecting your sensor to a display, you must account for
your output settings.
o 4mA at Bottom - The output current will be 4mA when the
sensor measures an empty tank and 20mA when the sensor
measures a full tank.
o 20mA at Bottom - The output current will be 20mA when the
sensor measures an empty tank and 4mA when the sensor
measures a full tank
Startup Condition
This feature allows the operator to select the output current on initial
startup prior to acquiring a true return signal (level measurement).
This only occurs during the initial powering of EchoSonic II and the
transmitter will revert to the correct level reading when the level is
acquired.
o Empty - Selects the start up current established in Output at
Empty. Example: Select 4 mA at Bottom, the output will
remain at 4 mA until the unit acquires a true return echo.
Select 20 mA at Bottom, the output will remain at 20 mA until
the unit acquires a true return echo.
o Mid Tank - When selected, the startup current will read 12
mA until the unit acquires a true return echo.
o Full Tank - Uses the opposite current that was selected in
Output at Empty. Example: If you select 4 mA at Bottom then
the start up current would be 20 mA. If you select 20 mA at
Bottom then the start up current would be 4 mA.
o Overfill (22mA) - The output at startup would be 22 mA. This
condition will remain until the unit acquires a true return echo.
Note: Right click on any menu that you may have questions on to open the help menu.
Note: To reset, press the Clear Screen button.

Installation in existing fittings
If the existing fitting is larger than the threads of the EchoSonic II, select a reducer bushing such as
the LM52-1400 (2” thread x 1” thread) or LM52-2400 (3” thread x 2” thread).
Metal Tanks (LU27 series)
Flowline ultrasonic transmitters have 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.
Fitting Selection:
Check the part number to determine the required fitting mount size and thread type. EchoSonic II
is commonly installed in tank adapters, flanges, brackets or standpipes. Note: Always include the
gasket when installing the EchoSonic II.
1. Tank Adapter: Select a tank adapter fitting, such as the LM52-1890 for the LU27 series
or the LM52-2890 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.

Note: Do not exceed the dimensions listed above
2.
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.
2” Flange w/
thread out of plane
2” Flange w/
thread in plane
2” Flange w/
Reducer Bushing
Do not use thread in plane
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.

4. Stand Pipe:
A standpipe maybe used to dampen turbulence or when foam is present in the application.
a. Pipe can be made of any material.
b. Select a minimum 3” ID pipe for the stand pipe.
i. A 2” pipe is usable with the LU27 series, but is the minimum.
ii. Pipes larger than 3” can also be used.
c. Use a coupling and reducer bushing to attach the EchoSonic II 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.
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.

Decrease Output Filtering: Placing a check mark in the box will eliminate all filtering
(averaging) of the analog output. Enables a pulse by pulse level reading. Use this filter to
see changes in level after every sound pulse.
Note: Never check increase output filtering and decrease output filtering at the same time.
Stabilize Output in Deadband: Placing a check mark in the box will activate a filter to hold
the output at Full if the level enters the dead band of the EchoPod. This filter requires the
level to leave the dead band at a smooth and steady rate.
Turn OFF Fast Level Changes: Placing a check mark in the box will turn off the filter
enabling fast level changes. Use this filter if your application has very smooth, slow and
steady level changes. The filter instructs EchoPod to look only for small incremental
changes in level.
Turn ON Noisy Mount Start Filter: Placing a check mark in the box will activate a filter
that reduces sound interference from the installation mount. Use this filter if the EchoPod
will not go to full range in the installation.

Updating Transmitter Firmware
WebCal software can also be used to update the firmware inside the EchoSonic II transmitter. This
feature allows the transmitter to be updated when new features are added. First open WebCal with an
EchoSonic II transmitter connected and the latest version of WebCal downloaded to your PC.
Click on the Updates Tab and then click on Select Program to select the Firmware update.
Select the latest version of the firmware file and click on OK.
Confirm that the address is correct and then click on Update Sensor to begin the firmware update. This
step should take less than 1 minute. You can follow the progress with the status bar to the right of the
Update Sensor button. When completed, click on the Configuration tab to configure the transmitter.
Remember, when the firmware has been updated, the unit will return to its original factory settings.
 If there is a communication interruption during the update, the process will stop. It is OK
to click on Update Sensor again to start the process over again.
Factory Default
Pressing the Factory Config button in the Configuration menu will return the screen to the
following settings. Out of the box, the EchoPod will output a 4-20 mA output that is maximized
for its operational range. The transmitter can be used in the original factory setting without
configuration with WebCal. Use the table below to identify the configuration of the sensor out of
the box.

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.

User Settings:
Check the wiring for an open circuit. An open circuit is the most common issue
with a 0 mA signal
Check the installation of the transmitter. 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.
Immediately check the wiring for a short circuit. The EchoSonic II is current
limited to 22 mA. Anything above 23 mA indicates a short circuit.
Check the dimensional configuration (Height and Fill-H) of the EchoSonic II.
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).
Check the Output at Empty Setting. Make sure the setting is correct (4mA at
bottom or 20 mA at bottom).
WebCal cannot detect an EchoSonic II 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.
This is a warning indicating the computer configuring EchoSonic II 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 II from being configured.
As choices are made in Configuration, WebCal will begin to eliminate functions
that are no longer active. To reset Configuration or get access to all the features,
click on the Clear Screen button.
