About the dBi Series (HART) Intelligent Transducer 

 

 

Functional Description 

The dBi Series Intelligent Transducer is a highly developed ultrasonic level 
measurement system which provides non-contacting level measurement for 
a wide variety of applications in both liquids and solids. Its unique design 
gives unrivalled performance in echo discrimination and accuracy in a loop 
powered device.   
Easy calibration and mai

ntenance free “fit and forget” performance mean 

that you can install the dBi Series Intelligent Transducer Level Monitoring 
System rapidly and with confidence, with calibration being achieved either 
using a HART programmer/calibrator, or via a PC utilising the Pulsar 
interface and software.
