EchoSonic Two-Wire Ultrasonic Level Transmitter photoEchoSonic II, Second Generation Two-Wire Ultrasonic Level Transmitter

The general purpose two-wire ultrasonic transmitter provides non-contact level measurement up to 32.8' (10 m), and is well suited for challenging ultrapure, corrosive, slurry or waste liquids. The transmitter is broadly selected for atmospheric bulk storage, day tank, waste sump, process vessel, IBC tote, 55-gallon drum and waste sump applications. Media examples include acetic acid and resin.

Features
  • WebCal, an innovative PC user interface that provides fast and accurate configuration
  • Offered in 3 measurement ranges up to 32.8' (10m)
  • Optimized sensor replacement with unmatched beam width (3") for applications with restricted space
  • Industry leading miniature dead band maximizes the filling capacity of vessels
  • Polycarbonate enclosure rated NEMA 4X with PVDF transducer

Fob USB®
The Fob USB interface tool (LI99-1001) and WebCal are necessary to change EchoSonic from the factory configuration.

One Fob will configure multiple EchoSonics.
