Description
The TRUE ECHO CR-L brings the accurate level readings of radar sensors to industrial
liquid measurements. It can accurately measure in many environments, including varying
temperatures, steam, dust, smoke, and foam. The radar's narrow beam can detect small
targets and achieve precise positioning with high resolution. It has a maximum measuring
range of 49.2 feet (15 m) and a minimum blind zone of 7.87 inches (0.2 m). All TRUE ECHO
CR-L sensors can be field calibrated and programmed via the TRUE ECHO Bluetooth app.
How To Read Your Label
2
Each sensor comes with a label on the body with a full model number, a part number,
and a serial number. The model number for the TRUE ECHO Radar Level Sensor will look
something like this:
SAMPLE: CR-L-GP-49-L1-P-E5-16-B0
The model number correlates with all the configurable options and tells you exactly what
you have. Compare the model number to the options on the datasheet to identify your
exact configuration. You can also call us with the model, part, or the serial number and we
can help you.

General Care

Your TRUE ECHO Radar is very low maintenance and will need little care, as long as it is
installed correctly. However, in general, you should:
Avoid applications for which the sensor was not designed, such as extreme temperatures,
contact with incompatible corrosive chemicals, or other damaging environments.
Inspect the threads whenever you remove the sensor from duty or change its location.
FCC Information
5
FCC regulations require 75-85 GHz radars to be installed to ensure a vertically downward
orientation at fixed locations only. They must not operate while being moved or while
inside a moving container. Hand-held applications are prohibited as well as marketing to
residential consumers.

Mounting Instructions
Mount your TRUE ECHO series radar so it has a clear, perpendicular path to the surface
being monitored. Your sensor should be mounted away from inlets and outlets.
The radar path should be free from obstructions and as open as possible for the 4°
off axis beam pattern.
Install the radar at least 7.9" (20 cm) away from side walls.
Wrap PTFE tape around threads before installing the radar. Do NOT over tighten.
Do not suspend by cable.
Ensure the radar is installed perpendicular to the measured surface.
Ensure there are no interferences within the beam angle, such as
walls, steps, ladders, river banks, etc.
Install the radar at least 7.9" (20 cm) away from side walls.
When installing in wells or pipes, place the radar as close
to the center as possible to avoid interference from side
walls.
When installing in tanks with domed lids, install off
center to avoid additional false echoes.
