EchoPulse

Pulse Radar Liquid Level Transmitter

LR30

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 remote push button display
module. The non-contact liquid level sensor is intended for industrial
wastewater, municipal storm or sewer lift station, reservoir, river, canal
or open channel applications located below or above grade. Select this
sensor for challenging process conditions that may include light surface
foam or agitation, small trash or plant material, wind, condensation
or vapor. Each comes with a 32.8’ (10m) cable, mounting bracket and
display module. The sensor is designed for bracket mount installation
suspended above the liquid level.

Features

Rugged IP68 sensor enclosure with 304 SS mounting bracket

Simple configuration via remote push button display module

26 GHz. pulse radar is unaffected by sump process conditions

Wall mounted display with windowed enclosure rated IP67

12” (30cm) dead band enables utilization of the entire sump

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

Self diagnostics with selectable fail-safe signal outputs

Recognition, storage and rejection of false echo signal returns

Success

Industrial and municipal pump
lift stations collect and transfer
wastewater into treatment. These
waste receptacles are very dynamic
environments that may contain dirt,
grease, oil, agitation, sludge, foam,
condensation, chemicals or vapor.
Here, a LR30 is mounted to the top
side wall of a 16’ sump. Its 26 GHz.
pulse radar measurement is unaffected
by the challenging process conditions.
