Inquiry (采购产品): LEVEL INDICATOR SYSTEM I am interested in a system that can indicate liquid level (up to 5,000 gals) in above-ground double walled tanks. The liquids are synthetic oils. Your system must transmit the level data up to five miles near and around aircraft flightlines. Since the oil tank will be geographically separated from maintenance operations (and not have electricity available) it will require a solar/battery power supply. Please e-mail me for additional information. Thank you. **** Hidden Message ***** RICHARD HOMBURG 08048 USA Company: R&J FLUIDIX E-mail: richard@rjfluidix.com **** Hidden Message ***** richard@rjfluidix.com
