EchoSonic II Ultrasonic Level Transmitter

  • Fast, easy PC user interface
  • Narrow beam angle is ideal for tight spaces
  • Short deadband allows full use of basin or tank



The new generation EchoSonic II two-wire ultrasonic transmitter provides non-contact level measurement up to 32.8’ and is ideal for lift stations, clear wells, chemical bulk and day tanks and many other level measurement applications. The EchoSonic II is programmed via WebCal, an innovative PC user interface that provides fast and accurate confi guration. The narrow beam angle allows optimal sensor placement for restricted areas and the short dead band maximizes filling capacity.

The Fob USB® interface tool (LI99-1001) and WebCal are necessary to change EchoSonics from the factory configuration. One Fob will configure all EchoSonics II and EchoPod units.
