EchoPulse® LR25 Pulse Radar Liquid Level Transmitter
Model :
LR25
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 process 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. Typical applications include process tanks.
