REFLECTIVE TECHNOLOGY
Condensation is the most common variable in liquid level applications. Condensation attenuates the acoustic
signal of ultrasonic sensors with horizontal transducers, weakening their signal strength and signal to noise
ratio by up to 50%, and substantially reducing their measurement reliability. At the core of Reflective
Technology™ is a simple fact. Unlike flat horizontal surfaces, significant water droplets cannot adhere to
smooth vertical surfaces. By orienting the transducer vertically, condensation runs off the transducer and does
not affect sensor performance. The unimpeded transmit and receive signals are redirected to and from the
liquid off a 45º reflector, delivering reliable level measurement.

Getting Started (continued) Step Two
WEBCAL® VS. DISPLAY CONFIGURATION
EchoTouch®can be configured using either the free WebCal®software and USB®Fob or with the internal
display module. Either method will accomplish the goal of sensor configuration. Changes to the configuration
can be made using the alternative method. Upon implementing one methodology, it is recommended to
complete the configuration before using the other methodology in making any adjustments.
EchoTouch®can be configured before installation or after installation. The transmitter features non-volatile
memory, so any settings configured before installation will not be lost when the sensor is powered down. To
start, the following information is required:
Basic Tank Information
oHEIGHT (Sensor Height) – Distance from
the bottom of the tank to the bottom of the
sensor.
oFILL-H (Fill-Height) – Distance from the
bottom of the tank to the fill-height of the
liquid.
Power:
oProvide input power to the Echotouch®
Note: The HEIGHT and Fill-Height (FILL-H) settings also determine the 4 to 20 mA current span. The
HEIGHT setting determines the 4mA position and the FILL-H setting determines the 20 mA position.

MN300820 Rev B4 15 |
Getting Started (continued) Step Two
UNDERSTANDING SENSOR HEIGHT (HEIGHT)
This is a critical setting for EchoTouch®. Sensor Height (SH) defines the location of the sensor from the bottom
of the tank. The value must take into account the shape of the tank and any risers, fittings, structures or
extensions associated with the tank or the installation (see examples below). The reference point for definition
of the Sensor Height is always the bottom of the mounting nut.
Simple Vertical Tank Dome Top Raises HEIGHT Sensor Off-center Changes HEIGHT
Simple Open Top Tank Sensor Extends into Sump Cone Bottom Elevates HEIGHT
Simple Horizontal Tank Riser Elevates HEIGHT Mounting Fixture Elevates HEIGHT

|16 MN300820 Rev B4
Getting Started (continued) Step Two
UNDERSTANDING FILL-HEIGHT (FILL-H)
This is another critical setting for EchoTouch®. FILL-H (Fill-Height) defines the location of the highest point in the
tank where the sensor will read level changes. When the level rises above FILL-H, the sensor will read full (as
long as the level does not enter the dead band). The reference point for definition of FILL-H is always from the
bottom location of the Sensor Height. The value must take into account the sensors dead band, any risers,
fittings, structures or extensions associated with the tank or the installation as well as the tanks geometry.
Example #1 – Flat Top Tanks
Tank A is a vertical tank with a flat top. The highest
value for FILL-H can be calculated by subtracting
the Dead Band from the Sensor Height.
FILL-H = Sensor Height – Dead Band
Tank B is another vertical tank with a riser that
matches the dead band of the sensor. In this case,
the FILL-H will be set to the top of the tank.
Note: The ratio of height to diameter of the riser
must be no greater than 2:1. Any higher and the
sensor will target the inside wall of the riser.
Example #2 – Dome Top Tanks
Tank C has a tall enough dome whereas the Dead
Band is above the straight side of the tank. The
FILL-H can be set to the top of the straight side
(this is advantageous because the top of the
straight side is typically a known volume of liquid).
The sensor is moved to a flat part of Tank D. As a
result, the Dead Band is now below the straight side
of the tank. FILL-H cannot be set to match the
straight side of the tank. Calculate FILL-H as
follows:
FILL-H =Sensor Height – Dead Band
Example #3 – Horizontal Tanks
Tank E is a horizontal tank with a rounded top. The
highest value for FILL-H can be calculated by
subtracting the Dead Band from the Sensor Height.
FILL-H = Sensor Height – Dead Band
Tank F is another horizontal tank with a riser that
matches the dead band of the sensor. In this case,
the FILL-H will be set to the top of the tank.
Note: The ratio of height to diameter of the riser
must be no greater than 2:1. Any higher and the
sensor will target the inside wall of the riser.

MN300820 Rev B4 17 |
Getting Started (continued) Step Two
Example #4 – Cone Bottom Tank
Tank G and Tank H are both vertical tanks that are
being supported above ground level with tank
stands. The location of the Sensor Height (Tank
G - bottom of tank or Tank H – ground level) will
influence the FILL-H setting.
Note: FILL-H must always be referenced to the
lowest location of the Sensor Height.
Since Tank G is off of the ground, the lowest
location may be difficult to identify/measure. This
location is required if the Volumetric Mode in
WebCal®is used.
Tank H uses ground level as the main reference
location. This method is easiest to use and ideal
for using the Distance mode of WebCal®.
Cone and Rounded Bottom Tanks
The location of an EchoTouch®installed along the top of a cone or rounded bottom tank may have an effect on
the installation of the sensor. Be sure to understand the geometry directly underneath the sensor. Cone or
rounded bottom tanks will provide off angled surfaces that can reflect the ultrasonic sound energy away from
the sensor as the liquid level is lowered.

Getting Started (continued) Step Two
SENSOR OUTPUT TO LOCAL DISPLAY/CONTROLLER
Echotouch®outputs a 4-20 mA signal to a local display/controller or to remote devices such as PLCs, SCADA,
DCS or other displays/controllers. The 4-20 mA signal is set relative to the Sensor Height and Fill-Height
settings. These settings create an operational range that can be translated into a level reading in defined units
(i.e. inches, feet, gallons, meters, liters, etc.).
Tank A Tank B Tank C
In the Tank A example, the Sensor Height sets the 4mA to the bottom of the tank. Fill-Height sets the 20mA to
the top of the straight side of the tank.
In the Tank B example, the 4-20mA sensor range is correlated to actual units of level measurement. The
operational range now will have engineering values of 0 to 10 feet or 0 to 1000 gallons or 0 to 120 inches.
In the Tank C example, the 20mA setting was lowered by 1 foot, so the engineering values for the new shorter
operational ranges are either 0 to 9 feet, 0 to 900 gallons or 0 to 108 inches.

Configuration Using WebCal®Step Three
EchoTouch®can be configured before installation. The transmitter features non-volatile memory, so any
setting configured before installation will not be lost when the switch is powered down. To configure, follow the
steps below:
1. Install WebCal®software
a. Go to www.flowline.com/webCal-software/ and select language version.
b. Review how USB®Fob interfaces with EchoTouch®and your computer.
2. Measure the Tank
a. Begin by measuring the key tank and fitting dimensions.
b. Correct tank dimensions will result in accurate sensor measurement.
3. Sensor Configuration
a. Configures Loop Fail-Safe, Output at Empty & Startup Condition for the sensor.
4. Dimensional Entry
a. Distance Mode (default)
i. Basic information for operation (Sensor Height & Fill-Height).
5. Tank Level Confirmation
a. Confirm the values are accurate for the application.
6. Write to Unit
a. Uploads configuration into the sensor.
b. Access to a customer wiring diagram specific to the relay configuration.
Note: When configuring EchoTouch®, choose either the WebCal®or Push Button method. Push
Button is only available with the US06 and US12 series. Either method will accomplish the goal
of sensor configuration. Changes to the configuration can be made using the alternative method.
When beginning with one method, it is recommended to complete the configuration before using
the other method to make any adjustments.
