Flowline, LR16-5021-20-00, EchoPro Pulse Radar Liquid Level Transmitter 26 GHz.,1-1/2" NPT, 2" (48mm) Horn, 316L, without FobThe intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 98.4' (30m) with a 4-20 mA signal output, and is configured via its integral push button display module or WebCal software. The non-contact liquid level sensor is intended for petroleum, water, wastewater and diluted chemical storage or process conditions in above or below grade tanks of any material. Select this sensor for challenging process conditions with diluted or non-corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a tank adapter, flange fitting or metal stand-pipe. Typical applications include bulk storage, tanker truck, RO storage, process tank, waste sump and neutralization tanks.Features:Rugged 316L stainless steel antenna and process mountConfiguration via push button display or WebCal software26 GHz. pulse radar is unaffected by vapor or condensation12" (30cm) dead band enables utilization of the entire tankLCD displays level in feet or meters with percent of span barOptional display mode indicates the echo signal return curveAuto-temperature compensation for accurate measurementFail-safe diagnostics with selectable signal fail-safe outputsRecognition, storage and rejection of false echo signal returnsIP67 stainless enclosure with polycarbonate display windowTo select the appropriate antenna size, consider four variables; The height of the tank, the amount of unobstructed measurement space under the sensor, the thickness of any surface foam and the dielectric of the liquid. In general, the taller the tank, the lesser the free measurement space, the thicker the surface foam or with dielectric values less than 10, consider an increasingly larger antenna.
