Enraf Flexline Radar 990
Honeywell Enraf FlexLine Radar 990 is a precision radar-based automatic tank gauge designed for accurate liquid-level measurement in large storage tanks. It combines advanced digital signal-processing algorithms with proven planar or horn antenna technology to deliver highly reliable level readings even in challenging conditions such as dome roofs, cramped stilling wells, or near-tank-shell installations. FlexLine Radar 990 is ideal for custody-transfer accuracy, inventory management, and overfill-protection applications at refineries, terminals, and petrochemical facilities.
Features
