Benefits
Offered in 3 level detection ranges from 9.8’ (3m) to 26.2’ (8m)
Confguration is simple via integral push button display module
Three programmable relays for switch; pump control and fail-safety
LCD display indicates level height in engineering units and relay status
Narrow 2” or 3” beam width for applications with limited measurement space
Short 4” or 8” dead band maximizes the measurable filling capacity of the tank
PVDF transducer and NEMA 4X polycarbonate enclosure for corrosive liquids
Automatic temperature compensation for accurate measurement
