Pulse Radar Liquid Level Transmitter
LR11
Application
The intrinsically safe 26 GHz. pulse radar level transmitter provides
continuous level measurement up to 32.8’ (10m) with a 4-20 mA analog
and HART digital signal output, and is configured via its integral push
button display module or HART communicator. 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 process 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

Corrosion Resistance
The US produces 40 million tons of
sulfuric acid per year that is widely used
in oil refining, wastewater treatment,
lead-acid battery and cleaning product
applications. In higher concentrations,
sulfuric acid is both extremely corrosive
and vaporous. The non-contact LR11
sensor is an excellent choice for this
application, as its 26 GHz. pulse radar
measurement is unaffected by vapor,
and the antenna and process mount are
encapsulated in corrosion resistant PFA
for years of reliable service. Select this sensor with confidence
in corrosive, vaporous applications.
