WELCOME TO THE ECHOSPAN® QUICK START

The EchoSpan® Quick Start provides basic setup and mounting instructions for getting EchoSpan® up
and running quickly. If you have a non-standard installation or setup requirement that is not addressed
here, please refer to the EchoSpan® Manual or support documentation at flowline.com.

WE DO YOUR LEVEL BEST™

Thank you for purchasing EchoSpan®. The general purpose ultrasonic level sensor provides non-contact
measurement up to 9.8’ (3m) with an integral LCD display and push-button menu configuration. This Quick
Start includes everything you’ll need to get the sensor up and running.

COMPONENTS

EchoSpan® comes with a Viton® gasket for installation and the Quick Start.

Enclosure

While the enclosure is liquid-resistant, EchoSpan® is not designed to be submersed, and should be mounted
in such a way that the enclosure and transducer do not come into contact with the application media under
normal operational conditions. The enclosure has a flip cover with dual 1/2” NPT female conduit ports and an
internal terminal strip for wiring. Before closing the enclosure, make sure that the enclosure gasket is
properly seated and that any conduit fittings, cable connectors or plugs are installed and sealed correctly.

Note: If using the Flowline LM90-1001 liquid tight fitting on the ½” conduit, the cable O.D. minimum is 0.170”
(4.3mm) and the maximum is 0.450” (11.4mm).

MOUNTING ECHOSPAN®

The sensor should always be mounted perpendicular to the liquid surface using the provided Viton® mounting
gasket. Make sure that there are no restrictions or obstacles in the path of the acoustic signal. For further
mounting information, please refer to the EchoPod® Manual at flowline.com.

EchoSpan® has 1” NPT or G threads and requires care in fitting selection and mounting to reduce any coupling of the
ultrasonic signal to the mounting structure. The below fittings are recommended.

• Installation in Existing 2” Fittings: Use a LM52-1400 2”
thread x 1” thread adapter or a LM52-1410 2” slip x 1”
thread adapter. Note: Adapters with air gaps around the
1-inch threads are recommended.

• Installation in Plastic Tanks: Use the LM52-1890 1”
bulkhead fitting; or a larger bulkhead fitting such as the
LM52-2890 with a reducer bushing such as the LM52­1400; or weld a plastic 1” half coupling to the tank top.

• Installation in Metal Tanks: Use the LM52-1890
bulkhead fitting; or a flange with a 1” riser such as the
LM52-1850 (where the threads are above the plane of the
flange); or a larger flange and add a reducer bushing such
as the LM52-1400. Note: Do not use a blind flange with a
tapped 1” thread. While installations directly into a
1”metal fitting are not recommended, acceptable results
may be obtained if the fitting is a half coupling and the
outer diameter of the coupling is tightly wrapped with vinyl
tape.

• Installation in Open Tanks or Sumps: Use Flowline's
LM50-1001-1 side mount bracket. Note: The bracket is
not designed for use with stand-pipes.

Mounting Guidelines

1. Never mount the sensor at an angle.

2. Liquid should never enter the sensor dead band.

3. Mount the sensor at least 2” from the side wall.

4. Never mount the sensor in a vacuum.

5. Do not obstruct the sensor beam width.

Stand-Pipe Installation

A stand-pipe may be used to dampen turbulence, separate surface foam from the point of measurement or
increase performance in heavy vapor. When mounting the sensor in a stand-pipe, the minimum diameter of the
pipe is 2”. Larger diameter pipes can be used. The pipe should be attached 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 sensor’s dead band. Locate the stand-pipe away from pump outlets
and/or other sources of substantial turbulence which might cause the liquid in the pipe to oscillate.

WIRING ECHOSPAN®

The following wiring diagram can be used to wire the 4-20 mA output of the EchoSpan®.

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.

• Wiring should always be completed by a licensed electrician.

• 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 environments classified as hazardous.

CONFIGURING ECHOSPAN®

EchoSpan® is configured using the three buttons on the sensor faceplate
(UP, DOWN and SELECT) and the LCD. To access the sensor’s TOP­LEVEL MENU, hold down the SELECT button for five seconds. The display
menu will automatically begin to scroll through the TOP-LEVEL MENU.

When the menu scrolls to an item you wish to configure, press the SELECT
button to choose that item. The TOP-LEVEL MENU will continue to scroll
through UNITS – TANK – SAFE – TGCAL – VALUES – HELP – RUN. If you
miss your selection, it will appear again shortly.

• To return to the TOP-LEVEL MENU, press SELECT when EXIT appears.

• To return to the Operational Mode, press SELECT when RUN appears in the TOP-LEVEL MENU.

• Note: To speed up the scrolling of the values on the display, hold down the SELECT button while

holding down the UP or DOWN buttons.

Units Configuration

EchoSpan® displays information in inches, feet, centimeters,
meters or percentage of span. The value shown on the display
represents the amount of liquid in the tank.

1) In TOP-LEVEL MENU mode, select UNITS.

2) Select the desired unit of measurement in INCHES, FEET,
CM, METERS or PERCNT.

3) Select EXIT to return to the TOP-LEVEL MENU.

Sensor Height and Fill Height Definition

The HEIGHT and FILL H settings determine the 4 to 20 mA
current span. As shown to the right, the Height setting reflects
the typical 4mA empty position and the Fill H setting reflects
the typical 20 mA full position.

• HEIGHT - Defined as the distance from the transducer face
to the bottom of the tank.

• FILL H – Defined as the maximum fill height of the
liquid from the bottom of the tank.

Sensor Height and Fill Height Configuration

The HEIGHT and FILL H settings determine the 4 to 20 mA current span. Follow these instructions to set the
HEIGHT and FILL H for your tank:

1) In the TOP-LEVEL MENU mode, select TANK.

2) Select HEIGHT.

3) Use the UP and DOWN buttons to set the
HEIGHT of your tank.

4) To enter the value, press and hold SELECT for 2
seconds and release. SAVED will display. HEIGHT
is now set.

5) Select FILL H.

6) Use the UP and DOWN buttons to set the FILL H
of your tank.

7) To enter the value, press and hold SELECT for 2 seconds and release. SAVED will display. FILL H is
now set.

8) Select EXIT to return to the TOP-LEVEL MENU.

9) Select RUN to return to the Operational Mode.

Fail-Safe Output / LOST Configuration

If the sensor does not receive a valid echo return, the Fail-Safe
Current Output or LOST setting can be set to output a current of
4mA, 20mA, 21mA, 22mA or HOLD (on the last known value).
During the fail-safe condition, the display will read LOST.

1) In TOP-LEVEL MENU mode, select SAFE.

2) Select 4mA, 20mA, 21mA, 22mA or HOLD. SAVED will
display.

3) Select EXIT to return to the TOP-LEVEL MENU.
