EchoPro® LR11 Pulse Radar Liquid Level Transmitter

DOWNLOADS

 

 

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 WebCal software. 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

Configuration via push button display or WebCal software

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

HART communication in point to point and multi-drop modes

Auto-temperature compensation for accurate measurement

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
