EchoPulse
Pulse Radar Liquid Level Transmitter
LR10
Application
The general purpose 26 GHz. pulse radar level transmitter
provides continuous level measurement up to 32.8’ (10m) 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 chemical or water storage applications in above
grade metal or reinforced concrete tanks or below grade tanks
of any material. Select this sensor for easy application conditions
with corrosive media, light agitation, condensation or vapor, and
installation in a low-profile tank adapter or flange fitting. Typical
applications include chemical bulk storage and tanker trucks.
Features
PFA encapsulated antenna and mount for corrosive media
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
The US produces 40 million tons of
sulfuric acid per year that is widely
used in fertilizer manufacturing,
wastewater treatment, oil refining,
lead-acid battery and cleaning
product applications. Here, a LR10
radar sensor is installed on a 22’
sulfuric acid bulk storage tank at a
chemical distribution company. With
a concentration of 62%, sulfuric acid
is highly vaporous and corrosive. The
LR10 sensor is an excellent choice for this application, as its 26
GHz. pulse radar measurement is unaffected by vapor, and both
the antenna and process mount are encapsulated in corrosion
resistant PFA for years of reliable service.
