• EchoPulse® LR25 Pulse Radar Level Transmitter






    The general purpose 6.3 GHz. pulse radar level transmitter provides continuous level measurement up to 114.8' (35m) 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 and petroleum storage or process applications in above grade metal or reinforced concrete tanks or below grade tanks of any material. Select this sensor for harsh application conditions with corrosive or low dielectric media, heavy surface foam or agitation, higher pressure, steam, condensation or vapor, and installation in a flange fitting. Due to the wider beam angle, special attention should be given to ensure that the sensor is located with unobstructed measurement space.



     316 L antenna with PTFE inner shield for corrosive media

     Simple configuration via integral push button display module

     6.3 GHz. pulse radar is unaffected by most foam and agitation

     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

     Auto-temperature compensation for accurate measurement

     Fail-safe diagnostics with selectable signal fail-safe outputs

     Recognition, storage and rejection of false echo signal returns

     Rugged IP67 aluminum enclosure with polycarbonate window
