7. Acoustic Leakage Detection 

 

 

In order to be able to carry out acoustic leak detection with the AquaM300, first activate the symbol for your 
acoustic leak detection measuring operation in the main menu and confirm your selection.  

The first selected mode is the pre-defined smart mode. There are two other modes available in addition to the smart mode: 
the F&V mode (frequency and volume) as well as the V mode (sound level). These measuring modes will be described in 
more detail in the chapters 7.2 to 7.4 below.  

Regardless of the measuring mode chosen, the following parameters can be set for all the measuring modes that can be 
used to carry out leak detection in the same consistent manner:  

 

 

(1) Sensor sensitivity setting  

 

 

 

(2) Selection of pre-defined filter settings  

 

 

 

(3) Volume setting  

 

 

7.1 Parameter Settings in the Acoustic Modes 

 

7.1.1 Adjusting the Sensor Sensitivity  

 

 

 

To set the sensitivity of the microphone connected to your 
leak detection device, navigate in the display window to 
the symbol for the sensor sensitivity setting (1), activate 
the symbol and confirm your selection.  

The sensor sensitivity settings window 
opens.  

 

The microphone amplification factor that has been currently selected is displayed on a scale from 0 to 100%. Turn the dial 
on the right or touch the touch screen and pull your finger to the sensitivity value which you would like to select. The 
sensitivity value is ideal when the control bar (2) on the left is half red, as shown.  

!!! Press the Cancel key (2) to activate automatic amplification. 

Press the Cancel key to leave the window without changing the sensitivity value. Press the dial on the right to confirm the 
new setting or press the Cancel key. You can also confirm your selection by pressing the symbol for the sensor sensitivity 
(1) on the touch screen.  

NOTE: The current measurement series will be cleared when any changes are carried out to the sensitivity 
settings!
