EchoPro” LR11 Pulse Radar Liquid Level Transmitter FLOWLINE 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. & C€©&F6 Features ■ PFA encapsulated antenna and mount for corrosive media ■ Configuration via push button display or HART communicator ■ 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 ■ Fail-safe diagnostics with selectable signal fail-safe outputs ■ Recognition, storage and rejection of false echo signal returns ■ IP67 stainless enclosure with polycarbonate display window 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. © 2019 Flowline I 10500 Humbolt Street, Los Alamitos, CA 90720 USA p 562.598.3015 f 562.431.8507 w flowline.com
