OPERATING PRINCIPLE

The sensor emits a microwave pulse from its antenna, which travels at the speed of light to the surface of the
medium below. A portion of that energy reflects off the medium and returns to the antenna. The time gap
between energy emission and receipt is called the “time of flight”, and is proportional to the distance between
the medium surface and the sensors measurement location, as at the bottom of the antenna. The sensor
measures the time of flight and translates this value into a continuous 4-20mA signal output that’s
proportionate to level within a defined measurement span.

FEATURES

 Easy configuration with LCD push button display module
 Adjustable loop fail-safe, no change, 20.5 mA, 22 mA
 Small 12” (30.48cm) dead band enables full tank measurement
 Recognition, storage and deletion of false echo signal returns

BENEFITS

 Unaffected by physical process and environmental conditions
 Ideal for applications with higher temp, pressure, foam, vapor and vacuum
 Strong signal penetrability with minimal attenuation over distance

LIMITATIONS (FACTORS THAT COULD INFLUENCE PERFORMANCE)

 Air particulates with a high dielectric constant value such as lead or ferroalloy
 Highly dense air particulates that attenuate microwave emission and receipt
 Material build-up on the antenna that degrades microwave emission and receipt
 Mediums that have an extremely low dielectric constant value with little reflectivity

SAFETY PRECAUTIONS

About this Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS

®

PRODUCT. This manual includes information on the EchoPro

Radar Level Transmitter from FLOWLINE.
Please refer to the part number located on the sensor label to verify the exact model, which you have
purchased.

User’s Responsibility for Safety: Flowline manufactures a broad range of level sensing technologies.

While each of these sensors is designed to operate in a wide variety of applications, it is the user’s
responsibility to select a sensor model that is appropriate for the application, install it properly, perform tests of
the installed system, and maintain all components. The failure to do so could result in property damage or
serious injury.

Proper Installation and Handling: Only professional staff should install and/or repair this product. Never

over tighten the sensor within the fitting. Always check for leaks prior to system start-up.

Wiring and Electrical: A supply voltage of 21.6 to 26.4 VDC is used to power the EchoPro®. Electrical

wiring of the sensor should be performed in accordance with all applicable national, state, and local codes.

Material Compatibility: The enclosure is made of either Aluminum or 316 Stainless Steel (refer to sensor

part number). The antenna is made of Stainless Steel (SS), Polytetrafluoroethylene (PTFE), Polyvinylidene
Fluoride (PVDF) or Nylon (PA66) with a Viton seal (refer to sensor part number). Make sure that the model,
which you have selected, is chemically compatible with the application media.

Enclosure: The sensor housing is media-resistant, but is not designed to be operational when immersed.

Mount the sensor in such a way that the enclosure and antenna do not come into contact with the application
media under normal operational conditions. The enclosure has a cover that provides access to the push
button display module and terminal strip for wiring. To open the enclosure, you will need to twist the cover
counter-clockwise. Before closing the enclosure, make sure that the enclosure gasket is properly seated, and

that any conduit fittings, cable connectors or plugs are installed correctly and sealed. Note: If using the

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

Make a Fail-Safe System: Design a fail-safe system that accommodates the possibility of sensor and/or

power failure. FLOWLINE recommends the use of redundant back-up systems and alarms in addition to the
primary system.

Flammable, Explosive or Hazardous Applications: EchoPro® is approved for use within intrinsically

safe applications ONLY and should NOT be used within classified hazardous environments.

Handling Static-Sensitive Circuits and Devices: When handling the instrument, the technician should

follow the below guidelines to reduce the possibility of an electrostatic charge build-up on the technician’s body
from being transferred to the electronic part. Always touch a known good ground source before handling a
part. This should be repeated while handling the part and more frequently after sitting down from a standing
position, sliding across the seat or walking a distance. Avoid touching electrical terminals of the part unless
making connections. DO NOT open the unit cover until it is time to work on the part.

Install Sensor Step Three

INSTALLATION REQUIREMENTS

EchoPro® measures the distance between the sensor and the media surface below. Typically, all
measurements from the sensor originate from the bottom of the antenna. Refer to the Measurement
Reference Chart to determine the location where measurement originates on your sensor. To ensure reliable
measurement, adhere to the following minimum installation requirements:

1) There are no obstructions between the bottom edge of the installed antenna and the surface of the media below
including ladders, walls, tank seams, media inflows, rails, other sensors, mixer blades, heating coils, pumps,

struts or apparatus. Note: Additionally, when the sensor transmits a microwave pulse, the RF signal spreads in
a conical shape (determined by its beam angle) over distance. Refer to the Beam Angle Chart to determine,

what if any, additional measurement space is required to be free of such obstacles. If such items are present,
then a False Echo Curve configuration must be conducted (Section Seven).

2) The sensor must be installed with the antenna perpendicular to the surface of the media.

3) The sensor must be installed with a distance ≥ 19.7” (500mm) from the side wall of the tank.

4) The media level must not be allowed to enter into the dead band (blanking zone) of the sensor.

5) The sensor installation must be done in accordance with relevant local or federal safety regulations.

6) The sensor must be connected to electrical ground.

7) Do not use the housing to screw the sensor into the installation fitting (LR36 & LR41 Series).

a) Applying force against the housing to tighten may damage the sensor.

8) Make sure that any part of the sensor as exposed to the application, specifically any portion installed within
the tank, are suitable for the process.

a) Consider any effects from the application temperature, pressure or media.

You can give your instrument additional protection against moisture
penetration by leading the conduit connection or cable downward in front
of the cable entry. Condensation in the conduit will therefore not enter

the sensor’s enclosure.

Install Sensor (continued) Step Three

GIMBAL MOUNTS (FOR SOLIDS)

Be aware of antenna’s length and width when using a gimbaled mount. The freedom of movement for the
gimbaled becomes less as the riser’s height increases.

SOLIDS INSTALLATION TIPS

In order to measure as much of the solids volume as possible, the antenna must be aimed at the lowest point
within the tank. With any cylindrical shaped tank with a cone bottom, the sensor should be mounted a distance
of half the radius (½R) from the side wall. If ½R cannot be met, it is preferred to mount the sensor closer to the
side wall and away from the center of the tank.

Avoid installing the sensor above the filling stream to avoid interference to the radar pulse. Locate the sensor
away from the filling stream.

MN301905 Rev A 25 |

Install Sensor (continued) Step Three

SOLIDS INSTALLATION TIPS (CONTINUED)

When using the gimbaled flange, the sensor can easily be mounted to direct the signal energy towards center
of the tank. The angle of the sensor will be dependent on the distance down to the bottom of the tank and the
distance away from the bottom of the cone. Use the chart below to understand the angle required to direct the
signal to the bottom of the cone.

Wire Sensor Step Four

REMOVE THE DISPLAY

To access the terminal strip and conduit ports, you
must remove the display. Gently twist the display
counter-clockwise until you feel the display unlock
from the housing. Next, lift the display from the
housing to view the terminal strip and wire access

ports. Note: This procedure applies to all sensors.

Note: There is an internal configuration difference between displays used by
the EchoPro
with the LR98 series. A colored dot on the back marks displays to be used
only with the LR98 series. Never swap displays between the LR98 series
and other EchoPro

®

sensors (LR36, LR41 & LR46 series) versus the display used

®

sensors.

SUPPLY VOLTAGE

The sensor power supply and current signal share the same two-wire shielded cable. The sensor supply
voltage should never exceed 26.4 VDC. Always provide complete electrical and physical separation between

the sensor supply circuit and the main circuit. Note: Remember that the output voltage of the power supply

can be lower under nominal load (with a sensor current of 20.5 mA or 22 mA) and/or with the addition of other
instruments placed within the circuit. If voltage spikes or surges are expected, adequate isolation protection
must also be provided.

TERMINAL WIRING

The positive (+) and Negative (-) terminals are for connection to a 24 VDC power supply or to a 4-20 mA loop
power source. The wire to the terminals can be extended up to 1,000 feet using 22 gauge or larger wire.

The sensor should be wired with shielded 2-conductor cable (16 to 22 AWG) to protect from electromagnetic
interference. If using a liquid tight connector, select a cable with an outer diameter that is designed to ensure
an effective seal with the connector [typically between 0.20” to 0.35” (5 to 9 mm)].

ELECTRICAL, USAGE AND SAFETY

1. Wiring should always be done by a licensed electrician in accordance with national, state and local codes.

2. Where personal safety or significant property damage can occur due to a spill, the installation must
have a redundant fail-safe backup system installed which accounts for sensor and/or power failure.

BASIC CONFIGURATION OVERVIEW

Below are the 7 basic steps to configure the sensor for operation. Each step is described in detail on the
following pages

1) Measure the Tank
a) Begin by measuring the key tank and fitting dimensions. Correct tank dimensions will result in accurate

sensor measurement.

2) Set the Units of Measurement
a) Units can be configured in basic engineering units of length including Feet or Meters.

3) Set the Sensor Height
a) This is the empty setting (4mA) for the tank.

4) Set the Fill-Height
a) This is the full setting (20mA) for the tank.

5) Set the Max. Range (Maximum Range or MaxR)
a) This is the maximum measurement range for the sensor. The sensor will ignore all echo returns

beyond this setting.

6) Set the Dead Band (Minimum Range or MinR)
a) This is the minimum measurement range for the sensor. The sensor will ignore all echo returns closer

than this setting.

7) Check the Echo Curve
a) This is a quick diagnostic tool to determine if the sensor is reading the correct level.

Note: When configuring EchoPro®, choose
either the WebCal

®

or Push Button method.
Either method will accomplish the goal of

Configuration (with Display, continued) Step Five

STEP 7 - CHECK THE ECHO CURVE

This function displays the primary echo return(s) that the sensor is seeing
graphically, the location and amplitude of the return(s), and the numeric air gap
distance from the sensor’s measurement location to the media level below.

Note: This step should only be performed after having completed the prior six
configuration steps with the sensor installed on the tank. Additionally, if the

sensor was installed in a stand pipe or sight glass, now go forward to Section
Six and turn on the still well function (Sensor Installed in a Stand Pipe or Sight
Glass) before continuing with this step.

1) From the Main Screen, press ESC and the Echo Curve Screen will appear.
The curve graphically represents the primary echo return(s) amplitude (Y­axis) over distance (X-axis). Above the echo return peak is a floating arrow
and triangle symbol (which under normal conditions are often merged
together or seen as a single triangle because it’s the larger of the two
symbols). The arrow represents the measured media level and the triangle
represents the peak amplitude location of the echo return. Under normal
conditions, expect to see a stable triangle (or overlapping arrow and
triangle) floating above a pronounced peak at the expected air gap distance
between the measurement location and media level.

2) In the upper right hand corner of the screen are two lines of numbers that
represent the air gap distance from the measurement location to the media
level (arrow) on the top, and peak amplitude location (triangle) of the echo
return on the bottom. Under normal conditions, these values should be
relatively close to one another and consistent with the expected air gap
distance between the measurement location and media level.

3) Assuming that the sensor is properly installed, if the measured media level
and peak amplitude location data (symbols and values) are unstable,
substantially different from one another and/or inconsistent with the actual
air gap distance, then this likely indicates that the sensor requires
additional process adjustment(s) described in the following Section Six.

4) When done, press ESC to return to the Main Menu.

STEP 7 - CHECK THE ECHO CURVE

®

) Step Five

This function displays the primary echo return(s) that the sensor is seeing graphically, the location and
amplitude of the return(s), and the numeric air gap distance from the sensor’s measurement location to the

media level below. Note: This step should only be performed after having completed the prior six configuration
steps with the sensor installed on the tank. Additionally, if the sensor was installed in a stand pipe or sight

glass, now go forward to Section Six and turn on the still well function (Sensor Installed in a Stand Pipe or
Sight Glass) before continuing with this step.

1) Click on the Echo Curve tab, then
on Echo Curve box and then on
Load.

2) The curve graphically represents
the primary echo return(s)
amplitude (Y-axis) over distance
(X-axis). Above the echo return
peak is a floating arrow and
triangle symbol (which under
normal conditions are often
merged together or seen as a
single triangle because it’s the
larger of the two symbols). The
arrow represents the measured
liquid level and the triangle
represents the peak amplitude
location of the echo return. Under
normal conditions, expect to see
a stable triangle (or overlapping
arrow and triangle) floating above
a pronounced peak at the
expected air gap distance between the measurement location and liquid level.

3) In the upper right hand corner of the screen are two lines of numbers that represent the air gap distance
from the measurement location to the liquid level (arrow) on the top, and peak amplitude location (triangle)
of the echo return on the bottom. Under normal conditions, these values should be relatively close to one
another and consistent with the expected air gap distance between the measurement location and liquid
level.

4) Assuming that the sensor is properly installed, if the measured liquid level and peak amplitude location
data (symbols and values) are unstable, substantially different from one another and/or inconsistent with
the actual air gap distance, then this likely indicates that the sensor requires additional process
adjustment(s) described in the following Section Seven.

Advanced Adjustments Step Eight

ADVANCED ADJUSTMENTS OVERVIEW

These optional functions are used to change the sensor output characteristics, or Create a False Echo Curve
to filter out false echo returns within the tank (improving sensor performance), or Update an existing False
Echo Curve filter if the original filter was not created during an empty tank condition.

1) 4-20 mA Rev Output - Reverses the

current output from 4mA @ bottom and
20mA @ top of tank to
and 4mA @ top of the tank.

2) Fail-Safe - Allows for the presetting of

the current output when a sensor
failure occurs. Options are no change
to current, 20.5mA or 22mA.

3) Minimum Current - Sets the minimum

current output for the sensor. Options
are 4.0mA or 3.9mA.

20mA @ bottom

4) Create a new False Echo Curve - A

method to filter out false echo returns
within the tank. This should be
performed when the tank is at its
lowest level (empty).

5) Update an existing False Echo
Curve - A method to update an
existing False Echo Curve to include a
lower section of the tank that was not
exposed during the creation of the

original Echo Curve. Note: If you don't

know the location (level position) or
validity of the original False Echo
Curve, it is recommended to delete the
original Echo Curve, and then create a
new False Echo Curve (versus
updating an existing False Echo
Curve).

MN301905 Rev A 55 |

Advanced Adjustments (continued) Step Eight

4-20 MA REVERSE OUTPUT

This function sets the current output at either 4-20 mA or 20-4 mA. Selecting 4-20 mA sets the output with 4mA
@ bottom and 20mA @ top of the tank. This is the standard output used in the majority of applications.
Selecting 20-4 mA sets the output with 20mA @ bottom and 4mA @ top of the tank. This is an optional output
sometimes used in applications where the level is maintained at a high level.

4 to 20 mA Output

1) From the Main Screen, press Enter to

advance into the Main Menu.

2) Press Right Arrow repeatedly until the arrow

is next to Service.

3) Press Enter to advance into Service Menu.

4) Press Right Arrow to move from Echo Curve

to Output Current.

20 to 4mA Output

5) Press Enter to advance into Output Current.

6) Press Enter to advance into 4-20mA Rev.

7) Press Right Arrow to change the setting

between 4-20mA and 20-4mA.

8) When the setting is correct, press Enter to

save.

9) When done, press ESC to return to the Service Menu and press ESC a second time to return to the

Main Screen or; if you want to advance directly into Fail-Safe, press Enter and then Right Arrow until
Fail-Safe appears. When done, press ESC to return to the Service Menu and press ESC a second time
to return to the Main Screen or; if you want to advance directly into Fail-Safe, press Enter and then

| 56 MN301905 Rev A

Advanced Adjustments (continued) Step Eight

FAIL-SAFE OUTPUT

This function is used to set the current output to a designated state if the sensor loses measurement
confidence. Selecting No Change will hold the current at its last valid current output. Selecting 20.5mA will

force the current to jump to 20.5mA. Selecting 22.5 mA will force the current to jump to 22.5 mA. Note: The

latter two high current output states are above the standard 4-20 mA operational range, and can be used to
indicate that a failure has occurred.

1) From the Main Screen, press Enter to advance into

the Main Menu

2) Press Right Arrow repeatedly until the arrow is next

to Service.

3) Press Enter to advance into Service Menu and Echo

Curve will appear.

4) Press Right Arrow to move from Echo Curve to

Output Current.

5) Press Enter to advance into Output Current menu.

6) Press Right Arrow to move from Reverse 4-20mA to

Fail-safe.

7) Press Enter to enter Fail-safe.

8) Press Right Arrow to change the setting between

No change, 20.5mA and 22.0mA.

9) When the setting is correct, press Enter to save.

10) When done, press ESC to return to the Service Menu and press ESC a second time to return

to the Main Screen or; if you want to advance directly into Min Current, press Enter and then

Right Arrow until Min Current appears.

CREATE A NEW FALSE ECHO CURVE

Obstructions in the tank (mixer blades, side wall weld joints or material build-up, submersible pumps, piping,
other apparatus) or tall tank risers or installation fittings can create false echo returns that impair the sensor’s
measurement. This function maps all echo returns within the tank, differentiating between good and false
echoes, and stores those identified as false into the False Echo Curve, so they will not be considered in the

level measurement. Note: A False Echo Curve should only be performed when the tank is empty so that all

false reflections will be detected. Before starting, measure and note the exact distance from the sensor’s
measurement location to the media surface. Setting the distance value too large or too short can force the
sensor into ignoring the true level.

Appendix (continued) Step Ten

The Low Dielectric Medium function has the following settings (and should not be performed without first
consulting with the factory):

When the dielectric constant of the media is ≤ 4, the amplitude of the direct
echo from the media may be low and difficult to detect. However, by
measuring the echo reflected from the bottom of the tank, the media level can
be measured. Two parameters must be input to complete the setup: 1)
Distance from the bottom of the sensor to the tank bottom (Empty Span) and;

2) Distance from the tank bottom to the media level (True Level).

 Empty Span - Distance from the bottom of

the sensor to the tank bottom.

 True Level - Distance from the tank bottom

to the media level.

 DK - Media dielectric constant (determined

by sensor).

Note: Once this feature has been activated, only a factory setting can undo
its activation. A factory reset will erase all active settings including Echo
Curves.

DAMPEN

TROUBLESHOOTING

Subject Comment

Display Shows E14: Sensor is in a Fail-Safe state. The return sound pulses are not

reaching the transducer. First, cycle power off and on, waiting 5
seconds between the off and on states. If problem persists, check the
installation fitting against the Installation instructions in the manual.

Display is opposite of the
measured value:

Transmitter indicates a
current of 0 mA:

Transmitter jumps to a
current reading between 19
and 20 mA:

Transmitter indicates a
current over 23 mA:

Time Out Error Occurred on
Command Zero

Check the Display Value setting (2.1). Distance mode indicates the
distance from the liquid to the sensor. Height mode indicates the height
of liquid in the tank. Change the Display Value from Distance to Height
or vice versa to correct. This setting does not affect the 4-20mA output.

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 EchoPulse® is
current limited to 22 mA. Anything above 23 mA indicates a short
circuit.

Check that VDC power is being applied to the sensor when using
WebCal

. The Radar Power LED should be blue with power. If it is

OFF, then power is not being applied. If power is applied, click on Try
