EchoPulse® General Purpose
Pulse Radar Liquid Level Transmitters
Best for Difficult Bulk Tank, Process or Sump Applications
These non-contact sensors are the reliable level measurement solution for your most
demanding storage, process and lift station applications.
WHY PULSE
Pulse radar is unaffected by process
conditions that cause other sensing
technologies to fail or require ongoing
maintenance. These include foam,
vapor, condensation, corrosion,
temperature, pressure, vacuum,
and coating or scaling liquids.
TECHNOLOGY
The radar sensor emits a 26 GHz or 6.3
GHz RF pulse from the base of the antenna.
The pulse travels through the free space,
reflects against the liquid dielectric material
and returns to the antenna. The sensor
measures the pulse time of flight and
translates it into liquid level distance.
The LR30 pulse radar
sensor is the reliable
level measurement
solution for municipal
and industrial pump
lift stations.

WHY ULTRASONIC
Ultrasonic is unaffected by liquid

Condensation attenuates the acoustic
signal of ultrasonic sensors with horizontal
transducers, weakening their signal strength,
and substantially reducing their measurement
reliability. By orienting the transducer vertically,
water droplets run off the transducer, and do
not affect sensor performance. The unimpeded
transmit and receive signals are reflected to

EchoWave® General Purpose
Guided Wave Liquid Level Transmitters
Best for Difficult Small to Medium Tank or Sump Applications
These contact sensors are the reliable level measurement solution for your day tank,
process tank, skid or machine and sump applications with challenging process conditions.
WHY GUIDED WAVE
Guided wave radar is unaffected by most
process conditions that cause other
sensing technologies to fail or require
ongoing maintenance. These include
foam, vapor, condensation, temperature,
pressure, vacuum, and light coating
or scaling liquids.
TECHNOLOGY
The guided wave sensor emits a RF pulse
from the base of the probe feed through.
The pulse travels down the probe, reflects
against the liquid dielectric material and
returns to the feed through. The sensor
measures the pulse time of flight and
translates it into liquid level height.

EchoPro® Intrinsically Safe
Pulse Radar Solids Level Transmitters
Best for Difficult Storage or Process Applications
These non-contact sensors are the reliable level measurement solution for your most
demanding silo, bin, stockpile, crusher and transfer station applications.
WHY PULSE
Pulse radar measures powders, grains,
aggregates, building materials or pellets,
and properly configured is unaffected
by process conditions that cause other
sensing technologies to fail or require
ongoing maintenance, such as dust,
material build-up or temperature.
SELECTION
TECHNOLOGY
The radar sensor emits a 26 GHz RF
pulse from the base of the antenna.
The pulse travels through the free space,
reflects against the solid dielectric material
and returns to the antenna. The sensor
measures the pulse time of flight and
translates it into solids level distance.
The LR36 and LR41
sensors are easily
installed with the
LR97 adjustable
mounting bracket.
To select the appropriate sensor for your application, consider that the stronger the RF signal, the greater the
sensors ability to overcome application variables such as process dust, low media reflectivity or dielectric value
and material buildup on the antenna. The RF signal strength increases by model and antenna size from the
LR36 with a 4” horn for easy process conditions to the LR46 with a 10” parabola for extreme processes.
