II. Inspection
a. Your Radar Level Transmitter unit was carefully inspec ted and certified by
our Quality Assurance Team before shipping. If any damage has occurred
during shipping, please notify Global Water Instrumentation, I nc . and f ile a
claim with the carrier involved.
b. Use the checklist to ensure that you have received everything needed t o
operate the Radar Level Transmit ter.
III. FCC Information for Users
a. Radar Level Transmitter Sensors have been tested and found to comply
with the limits for Class A digital device, pur s uant to Part 15 of the FCC
rules. These limits are designed to provide r easonable protection agains t
harmful interference when the equipment is operating in a commercial
environment. These sensors generate, us e, and can radiate radio
frequency energy and, if not inst alled and us ed in ac c or danc e with the
instructions, may cause interference with radio communications. Operation
of this equipment in a residential area is likely to cause interference that
the user will be required to correct.

IV. Features
a. The Radar Level Transmitter uses improved microwave pulse technology
to track any target material from t he tip of its antenna to the bottom of the
tank. Its power, pulse widths and sensit iv ity depend on the distance of the
target from the antenna and the dielectric cons tant of the reflecting
material.
b. The Radar Level Transmitter sensor features “echo mark er ” signal
processing, making it among the mos t technologically advanced pulse
radar system on the market. This technology will provide a r eli able
continuous pulse shape unaffect ed by env ir onmental c onditions such as:
c. Simple mounting and push-button calibration make for a very easy
installation. Calibration can be com pleted on the bench or in the field by
following simple instructions. The s ens or c an be threaded directly into a 2"
NPT metal or plastic flange. (See Installation section, page 14.)
d. The Radar Level Transmitter offers features such as:
1. Accurate, non-contact measurement
2. Works in conditions where ultrasonic is not acceptable
3. Pulse radar measurement range 10” to 50’
4. Simple push-button calibration
5. Standard 4-20mA signal output
6. Optional RS485 digital output
