Enraf Flexline Radar 990
Brand: Honeywell Process SolutionsThe SmartRadar FlexLine automatic tank gauge (ATG) combines innovative software algorithms with our proven planar antenna technology for the precision you need in custody transfer and inventory applications.
What is It?
Honeywell’s portfolio of radar tank gauges include:
- SmartRadar FlexLine suitable for highly accurate level measurement on large bulk storage tanks.
- SmartRadar FlexLine combines new software algorithms with Honeywell Enraf’s planar antennae technology to provide precision levels demanded for custody transfer accuracy.
- Free Space Antenna portfolio for SmartRadar FlexLine starts from smaller 6” antenna to 8” antenna, designed to address all installation needs on cone roof tanks. The planar antennas for stilling well covers stilling well application ranging from 6’ to 24’ diameter stilling wells.
How Does It Work?
In the most challenging circumstances such as dome roofs and bad stilling wells, SmartRadar FlexLine maintains its ultra-high-performance level on a wide range of applications and various tank conditions. The Enhanced Performance Signal processing enables the radar tank gauge to provide an accurate level reading even in difficult applications (close to the tank shell) and prevents the need for a costly stilling well. The FlexLine radar tank gauge has been certified for use in SIL-2 and SIL-3 applications by the TÜV which allows it to be used in overfill protection applications. Additional diagnostics have been added to detect hardware failures, while a 2004D voting algorithm will detect, report and isolate failures on the boards without interrupting the loading or unloading of a tank.
What Problems Does it Solve?
The FlexLine offers high flexibility that can be used for dedicated tank applications such as independent overfill protection, floating roof monitoring, rim fire detection, roof immersion compensation, etc. The FlexLine wireless option reduces the cost for wiring infrastructure and increases flexibility as various instruments can be added to the network without adding cables. The radar tank gauge is also certified for use in custody transfer applications.
