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 2 – SET THE UNITS OF MEASUREMENT

This function sets the units for all measurement values to be entered into the sensor. The choices for units are

feet and meters. The unit is shipped with a default setting of feet.

1. From the Main Screen, press OK to advance

into the Main Menu.

2. Press Right Arrow repeatedly until the arrow is

next to Service.

3. Press OK to advance into the Service menu

(Echo curve will appear).

4. Press Right Arrow repeatedly until the menu

shows Units of Measurement.

5. Press OK to advance into Units of

Measurement.

6. Press Right Arrow to change the setting

between feet [ft (d)] and meters [m (d)].

7. When the units are 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.

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.

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.
