EchoPulse® LR20 general purpose 26 GHz pulse radar level transmitter provides continuous level measurement up to 65.6 ft. (20m) range with a 4-20 mA signal output and is configured by an integral push button display module. This non-contact liquid level sensor is for chemical storage or process applications in above-grade tanks and below grade tanks of any material. Typical applications include bulk storage and process tanks. This sensor is for challenging process conditions with corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a flange fitting.
Features
- Configuration via integral push button display
- LCD displays level in feet or meters with percent of span bar
