INTRODUCTION / TABLE OF CONTENTS 

Step One 

The  EchoSonic®  II  is  a  general‐purpose  ultrasonic  level  transmitter  that  provides  a  loop  powered  4‐20  mA 
output.  The 4‐20 mA output can be used to provide the proportional level of liquid in any tank or vessel.  The 
signal can be connected to any device that accepts loop powered 4‐20 mA signals, such as a PLC, SCADA, DCS, 
display, controller, etc. 

New Features 

 

Simple configuration with WebCal® software, 

no more target calibration

. 

 

Adjustable Loop Fail‐Safe, Hold Last, Empty, Full, 21 mA, 22 mA 

 

Easy to reverse mA output, 4‐20 mA to 20‐4 mA 

 

Adjustable start‐up condition, Empty, Mid (12 mA), Full, Over range (22 mA)
