BASIC CONFIGURATION OVERVIEW
Below are the 9 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 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.
8) Install the Sensor
a) Review the installation requirements to assist in the mounting of the sensor.
9) Wire the Sensor

STEP 1 – MEASURE THE TANK
Measuring the tank is one of the most important aspects
in configuring the sensor. When measuring the tank,
take into account the location of the sensor with respect
to fittings, risers, dome tops and bottoms, and identify
where the measurements are taken from the sensor.
Note: The location for measurement may be different
among different sensor Series, based upon the type of
antenna. Refer to the Measurement Reference Chart for
the measurement location of your sensor. The basic
measurements for configuration are described below:
1) Distance from the sensor’s measurement location to
the bottom of the tank is the Max. Range value. The
Range value is typically set at the bottom of the tank.
2) Distance from the sensor’s measurement location to
the empty or lowest liquid level in the tank is the
Sensor Height.
a) Sensor Height = 4mA setting.
b) With flat bottom tanks, the Range and Sensor
Height values can be the same.
3) Distance from the sensor’s measurement location to
the full or highest liquid level in the tank is the Fill-
Height.
a) Fill-Height = 20mA setting.

CONE BOTTOM TANKS
When installing the EchoPro® on a tank with a cone bottom, the geometry of the bottom part of the tank can
influence the sensor’s configuration. If your requirement is to measure into the cone, location of the sensor is
critical. However, if your requirement is only for the straight side of the tank, the location of the sensor is not critical.
Straight Side Only Reading into the Cone Reading to the Bottom
The location of the sensor is not
critical because the lowest level
reading is within the straight side of
the tank.
Sensor can read into the cone, but
only to where the majority of
energy reflects back to the sensor
and not away from the sensor.
Sensor must be installed over the
lowest part of the tank in order to
provide the best path allowing
energy to travel down to the tank
bottom.
TOP OF TANK CONSIDERATIONS
Below are some considerations with respect to how the sensor can be installed on top of a tank. EchoPro®
has a dead band that extends from the measurement location of the sensor. As a result, the height of the
sensor above or below the top of the tank will affect the dead band and 20mA settings.

STEP 3 – SET THE SENSOR HEIGHT (4mA)
This function sets the Sensor Height point corresponding to an empty position in the tank. The measured
distance of Sensor Height from the sensor will set the 4mA location as well as establish the 0% span of the
sensor.
1. From the Main Screen, press OK to advance
into the Main Menu.
2. Press OK to advance into the Configuration
Menu.
3. Press OK to advance into Empty
Configuration. The first percentage segment
will be highlighted.
4. Press OK again to switch to the distance (d)
setting.
5. Press Right Arrow to move one segment to
the right. Right Arrow will scroll left to right
and then back to the first segment.
6. Press Up Arrow to increase the value of the
number highlighted. Up Arrow will scroll
from 0 to 9 and back again.
7. When the value is correct, press OK to save
the setting.
8. When done, press ESC to return to the Main Menu, and press ESC a second time to return to the
Main Screen or; if you want to advance directly into Full Configuration, press Right Arrow.
| 10 QS301900 Rev B
STEP 4 – SET THE FILL-HEIGHT (20mA)
This function sets the Fill-Height point corresponding to a full position in the tank. The measured distance of
Fill-Height from the 0% or empty position will set the 20mA location as well as establish the 100% span of the
sensor.
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 advance into Full
Configuration.
4. Press OK to advance into Full Configuration.
The first percentage segment will be highlighted.
5. Press OK again to switch to the distance (d)
setting.
6. Press Right Arrow to move one segment to the
right. Right Arrow will scroll left to right and
then back to the first segment.
7. Press Up Arrow to increase the value of the
number highlighted. Up Arrow will scroll from 0
to 9 and back again.
8. When the value is correct, press OK to save the setting.
9. When done, press ESC to return to the Main Menu, and press ESC a second time to return to the Main
Screen or; if you want to advance directly into Range, press Right Arrow repeatedly until Range
appears.
