Welcome to the EchoSpan® Quick Start

The EchoSpan® Quick Start is meant to show some of the more common
setup solutions to getting the EchoSpan® 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 EchoSpan® Manual or
refer to the Flowline website at www.flowline.com.

Select Fail Safety Output

We Do Your Level Best

Thank you for purchasing Flowline’s EchoSpan®. The EchoSpan® provides a 4-20 mA
analog output with integrated LCD and three push-button configuration. This Quick
Start includes everything you’ll need to get the transmitter up and running. For
complete information, please refer to EchoSpan® documentation located at

www.flowline.com.

Components

Depending on the model shipped to you, you should have the components shown
below. Both components – the EchoSpan® and Viton® gasket – are required to install
the EchoSpan®.

In the event the transmitter does not receive an
echo, the Select Fail Safety Output setting can be
set either to 22mA, 21mA, 20mA or HOLD the last
value to achieve the desired fail-safe condition.
During fail-safe, the display will read LOST.

1) Enter the configuration menu
(as discussed previously),

2) Select SAFE from the menu,

3) Select an output option, such as 22mA,
21mA, 20mA, 4mA, or HOLD, and

4) Select EXIT to return to the Configuration menu.

Reverse 4-20 mA Signal

The transmitter allows you to switch the 4-20 mA value at the top and bottom of the
application. By default, 4mA is configured as the bottom and 20mA is configured as
the top. The transmitter displays this as NORM. Follow these instructions to reverse
this setting:

1) Enter the configuration menu
(as discussed previously),

2) Select TANK from the menu,

3) Select Rev MA from the
menu,

4) Then, select Rev from the
menu, and

5) Select EXIT to return to the
Configuration menu.

Troubleshooting

If you face any issues not addressed in this quick start, please refer to the EchoSpan®
Manual located on Flowline website at www.flowline.com.

Mounting the Transmitter

The transmitter displays information in inches,
feet, centimeters, meters, or percentages.

This can be displayed to represent the amount
of air or the amount of liquid in a tank.

Air Display Mode shows the distance from the
bottom of the sensor to the liquid surface. Liquid
Display mode show the distance from the liquid
surface to the bottom of the tank.

Follow these instructions to set how units are displayed:

1) Enter the configuration menu (as
discussed previously),

2) Select UNITS from the menu,

3) Select the type of unit or the type of
DISPLAY you desire, and

4) Select EXIT to return to the Configuration
menu.

Set Height and Fill Height

This setting customizes the reading for your installation. Follow these instructions to
set the height and fill height for your tank:

The Transmitter should always be mounted perpendicular to the liquid surface and
installed 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. An instructional video on this is also
available on the website.

The LU80 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:

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” Bulkhead
fitting,

2) Use a Bulkhead fitting LM52-2890 in combination
with LM52-1400 or,

3) Weld a plastic 1” half coupler to tank top.

1) Enter the configuration menu (as discussed previously),

2) Select TANK from the menu,

3) Select HEIGHT. Use the UP and DOWN buttons to set the height of your tank. Then,

hold down the SELECT button to save this setting,

4) Select FILL-H for the fill

height. Use the UP and
DOWN buttons to set the fill
height of your tank. Then, hold
down the SELECT button to
save this setting, and

5) Select EXIT to return to the

Configuration menu.

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. Drilling and tapping a blind
flange is not recommended.

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.

A standpipe may be used to dampen turbulence,
separate surface foam from the point of measurement
or increase performance in heavy vapor. Select a 2”
pipe and attach the transmitter 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 oscillate. Mounting with a Standpipe

IMPORTANT MOUNTING GUIDELINES:

1) Never mount the sensor at an angle.

2) Liquid should never enter the dead band.

3) Mount at least 3” from the side wall.

4) Never mount in a vacuum.

5) Do not obstruct the sensor’s 2” beam width.

6) Isolate air gaps between inner and outer threads for best performance.

Some final notes on safety:

 Where personal safety or significant property damage can occur due to

a spill, the installation must have a redundant backup safety system.

 Wiring should always be completed by a licensed electrician.
 Supply voltage should never exceed 28 VDC.
 The sensor must be chemically compatible with the application.
 Design a fail-safe system for possible sensor and/or power failure.
 Never use the sensor in classified hazardous

environments.

Configuring the Transmitter

The transmitter features a non-volatile memory,
and can be configured prior to installation. Your
configuration will not be lost when the transmitter is
powered down. Before configuring, be sure to have
the following information:

Height. This is the distance from the transducer

face to the bottom of the tank.

Fill Height (Fill-H). This is the distance from the

highest level of liquid to the bottom of the tank

Wiring the Transmitter

The following wiring diagrams can be used when wiring the transmitter.

Configuration Menu

The transmitter is configured with the three buttons
on the transmitter’s face (UP, DOWN and SELECT)

and the transmitter's LCD. To access the
transmitter's
configuration menu, simply hold down the SELECT
button for five seconds or until the menu is
displayed.
When the SELECT button is released, the display
menu will begin to scroll through the uppermost level
of the configuration menu.

When the menu scrolls to an item you wish to configure, simply press the SELECT
button again when that item appears. Once you've made your configuration changes,
press SELECT again when “Exit” appears to scroll through the options and once
more while RUN appears in the display. This will return the transmitter to its
operational mode.
