MEASURE THE TANK (BASIC DIMENSIONS)
EchoBeam®measures the distance between the
sensor and the liquid or solids surface below.
Measuring the tank is one of the most important
aspects in configuring the transmitter. When
measuring the tank, consider the location of the
transmitter with respect to fittings, risers, dome
tops and bottoms, and identify where the
measurements are taken from the transmitter. The
basic measurements for configuration are
described to the right:
• Sensor Height
• Fill-Height
All measurements are made from the bottom of the
tank up to the bottom of the sensor (Sensor Height)
or to the operational full for the tank (Fill-Height).
Example: Mounting in a Solid
Example: Mounting in a Liquid

AD310320 Rev A 9 |
Configuration Using Display Section Three
CONFIRM THE TANK MEASUREMENTS
All measurements with EchoBeam®are referenced from the bottom of the transmitter. Once the transmitter
has been installed, you may need to adjust your original measurements due to the location of the EchoBeam®
in the application. Shown below are the offsets from the bottom of the EchoBeam®to the top of the
mounting threads. Use the offsets to calculate the exact location of the transmitter’s point of measurement.

STEP 8 - CHECK THE ECHOCURVE
EchoCurve presents a physical representation of the return signal across the operational range for the radar
transmitter. From the Main Screen, press ESC to view the EchoCurve.
There are two components to observe when looking at the EchoCurve:
• Check the Peak(s) along the EchoCurve
o Ideally, there should be a significant peak which
represents the liquid or solids level in the tank.
o This peak should be above the Envelope Line
(Threshold Filter).
o There may be more, and smaller peaks located
before and after the large peak.
Echo Peaks along the EchoCurve
• Check the Location of Peak (Return)
o There are two values above EchoCurve.
o The bottom value represents the air gap
distance from the radar transmitter to the liquid
level.
o The top value represents the air gap distance
from the radar transmitter to the peak amplitude
location.
Location of Echo Return
o These two values should be close to one another (or the same value).
§ The example above indicates that the liquid level is located 7.208 feet away (Bottom
Value) and the peak amplitude is located 7.208 feet away (Top Value) from the radar
transmitter.
§ The liquid or solids level should be at this peak location.
• Change the Distance Scaling
o The distance scaling for the EchoCurve defaults to a scale of 0 to 118’ (0 to 36m) for the LR83
and 0 to 393’ (0 to 120m) for the LR85.
o Press Up Arrow to change the Scale
• Show the Envelope Curve
o The Envelope Curve does not appear when the EchoCurve is first viewed (default).
o To show the Envelope Curve, press Right Arrow.
o To remove the Envelope Curve, press Right Arrow.

ADVANCED ADJUSTMENTS OVERVIEW
These optional functions are used to change the transmitter output characteristics.
Note: These adjustments should only be performed after having completed the configuration steps previously
described with the transmitter installed on the tank. Where so, perform the following applicable Advanced
Adjustments.

• Maximum Range
• Reverse mA
• Distance Adjust

|20 AD310320 Rev A
Advanced Configuration Using Display (Range Adjust) Section Four
DEAD BAND
This setting defines the minimum distance that the EchoBeam®will detect valid echo returns. EchoBeam®
will not read a level above this setting. All values will be in the Units previous defined during configuration.
Default setting will be at 90% of the difference between the Sensor Height and Fill-Height values.
• If Sensor Height = 20 feet and Fill-Height = 19 feet, the difference between the two values is 1 foot.
• 90% of 1 foot is 0.9 feet (set Dead Band to 0.900 feet)
1) From the Main Screen, press OK to
advance into the Main Menu.
2) Press OK to advance into the
Configuration Menu.
3) Press Right Arrow to switch to
Advanced.
4) Press OK to advance into Advanced
Menu.
5) Press OK to advance into Range
Adjust. Menu.
6) Press OK to change the value for
Dead Band.
a) Press Up Arrow to increase the
value of the number highlighted.
Up Arrow will scroll from 0 to 9
and back again.
b) Press Right Arrow to move one
segment to the right. Right Arrow
will scroll left to right and then
back to the first segment.
c) When the value is correct, press
OK to save the setting.
7) When done, press ESC to return to
the Range Adjust Menu, press ESC to
return to the Advanced Menu, press
ESC again to return to the
Configuration Menu and press ESC a
fourth time to return to the Main
Screen, or If you want to advance
directly into Maximum Range, press
Right Arrow.
Note: Dead Band is completely independent from the 20mA setting (Fill-Height). If the Dead Band is set
below the location of the Fill-Height, then the transmitter will not measure above the Dead Band. The
maximum level will not correspond to the current at the Dead Band.
