About the 

Sludge Finder 2

 

 

The single Sludge Finder 2 unit provides dual point level sensing in liquids 
and/or air.  
 
Easily installed, conduit entry on unit via 5 x 20mm Knockouts and 1 x 16mm 
knockout. 

 

Outstanding stability, accuracy and repeatability. 

 

Sophisticated algorithms for echo extraction utilizing powerful Digital Signal 
Processing (DSP) microprocessors. 

 

Superior performance based on current leading edge technology and modern 
design procedures. 
 
Two independent transducer channels with the option of combining 
submersible and air transducers 

 

Two fully adjustable 4-20 mA outputs  

 

Six fully programmable SPDT status relays  

 

RS232 and

 

RS485 communications ports for multiple unit installations. 

 
Radio communications for remote 4-20mA Indication (optional). 

 

All these features and more plus the ease of programming, make this 
instrument the number one choice for interface level measurement in liquids.
