§3.3 Transducer Spacing 

 

V-Method Installation 

The V-method installation is the most widely used method for daily measurements.  The inner diameter of 

the pipe ranges from 

20mm to 300mm

. It is also known as the 

reflective method

.  The small sound path 

of pipes in this range can interfere with accuracy.  This method doubles the sound path, thus, ensuring an 

accurate measurement.

Z-Method Installation 

The Z-method is commonly used for pipe diameters between 

300mm and 5,000mm

.  Signal strength is 

increased with this method.  

 

 

 

 

 

 

STOP! 

Before mounting, please read Section §3.3!  
Transducer spacing is critical to the accuracy of 
the meter readings
