SENSOR MODELS
Offered in four different models, EchoBeam®is an FMCW radar level sensor that provides a continuous output
proportional to the liquid level in a tank or sump. Available outputs include 4-20mA, 4-20mA w/ HART, ModBus
RTU and SDI-12. Make sure the model purchased is appropriate for your application.

Introduction Section One
OPERATING PRINCIPLE
Flowline’s EchoBeam is frequency modulated continuous wave (FMCW) radar that operates at 80 GHz
normally. The antenna transmits high frequency as well as the frequency modulated radar signal. The
frequency of the radar signal linearly increases. The transmitter radar signal is reflected by the dielectric of the
liquid and/or solid to be measured and received by antenna. At the same time, the difference between the
frequency of transmitter signal and that of the received signal is proportional to the measured distance.
Therefore, the distance is calculated by the spectrum derived from the analog-to-digital conversion frequency
difference and the Fast Fourier Transform (FFT).
FEATURES
•High frequency, small beam angle and smaller dead zone enable measurement in small diameter tanks
of both metallic and non-metallic construction.
•Centralized energy and stronger anti-jamming capability that has significantly improved measurement
accuracy and reliability.
•Small antenna size that facilitates the installation in smaller tanks.
BENEFITS
•80GHz radar can achieve small beam angles with smaller diameter antennas allowing for greater
avoidance of obstacles within an application.
oAvoiding mixer blades, pipes, ladder rungs, conduit, chains or anything else you can find in a
tank or sump is easier with a narrow beam angle.
•Easy to retrofit other technologies with the smaller antenna and packaging.
•Use of thermo-plastics to construct a transmitter compatible with corrosive materials thus avoiding the
typical radar issue of 316 SS compatibility.
LIMITATIONS (FACTORS THAT COULD INFLUENCE PERFORMANCE)
•Air particulates with a high dielectric constant value such as lead or ferroalloy.
•Highly dense air particulates that attenuate microwave emission and receipt
•Material build-up on the antenna that degrades microwave emission and receipt.
•Liquids or Solids Media that possess an extremely low dielectric constant value with little reflectivity
