Introduction Section One
SENSOR MODELS
Offered in five different models, EchoPulse® is a general-purpose, two-wire, pulse radar level sensor
that provides a continuous 4-20 mA current output that’s proportional to the liquid level in a tank or
sump. Make sure that the model purchased is appropriate for your application.
OPERATING PRINCIPLE
The sensor emits a microwave pulse from its antenna, which travels at the speed of light to the
surface of the medium below. A portion of that energy reflects off the medium and returns to the
antenna. The time gap between energy emission and receipt is called the “time of flight”, and is
proportional to the distance between the medium surface and the sensors measurement location,
which is typically located at the bottom of the antenna. The sensor measures the time of flight and
translates this value into a continuous 4-20mA signal output that’s proportionate to level within a
defined measurement span.
FEATURES
 Easy configuration with LCD push button display module
 Adjustable loop fail-safe, no change, 20.5 mA, 22 mA
 Small 12” (30.48cm) dead band enables full tank measurement
 Recognition, storage and deletion of false echo signal returns
BENEFITS
 Unaffected by physical process and environmental conditions
 Ideal for applications with higher temp, pressure, foam and vapor
 Strong signal penetrability with minimal attenuation over distance
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
 Mediums with an extremely low dielectric constant value with little reflectivity
