Echotouch™, EchoSpan® &
EchoSwitch® Ultrasonic Liquid
Level Sensors
The Echotouch, EchoSpan and EchoSwitch are innovative
ultrasonic liquid level sensor families that replace float,
conductance and pressure sensors that fail due to contact with
dirty, sticky and scaling media in small, medium and large
capacity tanks. Applied in chemical, water and wastewater
applications, these general purpose non-contact sensors are
available with single and multi-function capabilities including
continuous level measurement, switching and control.
For input to a PLC or other controller, measurement outputs
include current, voltage and frequency. Models with three
relays can be configured for level alarms and/or stand-alone
level control such as automatic fill or empty functions using the
embedded level controller. Units are easily configured using
built -in pushbuttons.

Example - EchoSpan Display and Menu
With no software or PC required, the Echotouch, EchoSpan, and
EchoSwitch ultrasonic level sensors are easily configured using
integral pushbuttons and LCD digital display. Configuration
parameters are organized in a simple menu structure so that
parameter values are easily accessed and set or changed as
needed. Parameters are stored in non-volatile memory so the
setting values are not lost when the sensor is powered down,
allowing configuration before installation in the field.

Echotouch™ LU20 Ultrasonic
Level Transmitter
Overview
Features
The Echotouch LU20 ultrasonic level transmitter is
CSA approved for intrinsically safe applications. The
two-wire ultrasonic transmitter provides non-contact
measurement up to 18 ft (5.5m) and is ideally suited
for corrosive, slurry or waste liquids. The transmitter
is typically selected for atmospheric bulk storage,
day tank and waste sump applications located
within a classified hazardous area. Media examples include diesel fuel and hydrochloric acid. The
transmitter is calibrated in less than a minute using
the LCD display, 4-button interface and intuitive
calibration menu. All user setpoints are held in nonvolitile memory. In the event of acoustic signal loss,
the transmitter will hold the current output at the user
designated safe state.
Part No. LU20-5001-IS
• LCD digital display indicates level in inches or
centimeters
• Polypropylene enclosure rated NEMA 4X / IP65 with
rugged Kynar transducer
•Simple pushbutton calibration for all user setpoints
• Adjustable dead band and range filters eliminate
false echo returns
Agency Approvals

Beam Cone Data
The “Beam Cone” is the amount in which
the ultrasonic wave increases in diameter (Radius²) as the wave travels away
from the sensor. This is important to note
during installation to prevent objects in the
tank from providing false echoes.

When installing the 1” NPT level sensors care should be used to mechanically isolate the sensor housing from the tank. This can easily
be done by using any of the Flowline mounting accessories which are designed to provide the isolation needed.
