EchoPulse
Pulse Radar Liquid Level Transmitter
LR15
Application
The general purpose 26 GHz. pulse radar transmitter provides
continuous level measurement up to 98.4’ (30m) with a 4-20
mA signal output, and is configured via its integral push button
display module. The non-contact liquid level sensor is intended
for petroleum, water, wastewater and diluted chemical storage
or process applications in above or below grade tanks of any
material. Select this sensor for challenging process conditions
with low or non-corrosive media, light surface foam or agitation,
higher temperature or pressure, condensation or vapor, and
installation in a tank adapter, flange fitting or metal stand-pipe.
Typical applications include bulk storage, tanker truck, process
tank, waste sump and neutralization tanks.
Features
Rugged 316L stainless steel antenna and process mount
Simple configuration via integral push button display module
26 GHz. pulse radar is unaffected by vapor or condensation
12” (30cm) dead band enables utilization of the entire tank
LCD displays level in feet or meters with percent of span bar
Optional display mode indicates the echo signal return curve
Auto-temperature compensation for accurate measurement
Fail-safe diagnostics with selectable signal fail-safe outputs
Recognition, storage and rejection of false echo signal returns
Rugged IP67 aluminum enclosure with polycarbonate window
Success
There are 612k restaurants in the
US that generate waste vegetable
oil. Viscous with floating particulate
and animal fat, waste oil is difficult
to measure. Rendering companies
collect, process and sell waste oil
to secondary markets. Here, a LR15
is flange mounted on a 23’ storage
tank at an oil rendering plant. Its 26
GHz. pulse radar measurement is
unaffected by the process condition.

NOTES
If you want help in selecting a sensor for your application, please go to our
1)
website and submit a Level Questionnaire. An engineer will review your
requirements and suggest a product solution via email.
To install the radar sensor with a flange or reducer bushing, order the fitting
2)
separately, and follow the antenna preparation instructions in the manual.
