EchoPulse LR20 Radar Liquid Level Sensor Transmitter
The general purpose 26 GHz. pulse radar level transmitter provides continuous level measurement up to 65.6’ (20m) with a 4-20 mA signal output, and is configured via its integral push button display module. The non-contact liquid level sensor is intended for chemical storage or process applications in above or below grade tanks of any material. Select this sensor 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. Typical applications include bulk storage and process tanks.
