The general purpose ultrasonic multi-function level transmitter provides continuous level measurement up to 49.2” (1.25m) with a 4-20 mA analog signal output and four relays, and is configured via our WebCal software. Each relay can be configured for alarm, automatic fill or empty functions. Select this sensor for small tanks with non-foaming, non-condensing or highly vaporous media such as chemicals, water, wastewater and oil. Typical applications include chemical feed, skid or machine, IBC or drum and small waste sumps.


  • Level measurement, switch and control functions up to 49.2” (1.25m)
  • Configuration is fast and easy via WebCal software and USB adapter
  • Narrow 2” beam width and short 2” dead band optimized for small tanks
  • Four programmable relays for switch, pump or valve control and fail-safety
    • 1 pump or valve with 3 alarms
    • 2 pumps lead-lag with 2 alarms
    • 2 pumps duplexing with 2 alarms
    • 4 independent switch point alarms
  • PVDF transducer and 6P polycarbonate enclosure for corrosive liquids
  • Automatic temperature compensation for accurate measurement
