Flowline EchoPulse® LR20 Non-Contact Liquid Level Sensor Transmitter w/ 26 GHz Pulse Radar, 65.6 ft. Range, General Purpose

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
• 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
• 26 GHz. pulse radar is unaffected by vapor or condensation
• 12 in.(30cm) dead band enables utilization of the entire tank
• 316L stainless steel antenna with PTFE inner shield for corrosive materials
• Rugged IP67 aluminum enclosure with polycarbonate window
