Sono-Trak™ Doppler Ultrasonic Flow Meter

Your Doppler flow meter is now configured to measure flow per the parameters you 
have set. After you set the flow reading parameters you need for your system, you can 
secure these settings so they are saved in the event of power loss to the electronics 
enclosure. 

Note: To clear the rate and totalizer parameters you have set, simply switch the power 

off using the on/ off switch on the display panel. Until settings are saved using 
the security switch, turning off power clears all previously set parameters. 
When you turn on power again, the LCD screen will prompt you to restart 
programming.

1. Complete setting the flow reading parameters (see 

 to set parameters).

2. Unscrew the face of the display panel to expose the processor board by turning 

both white plastic screws on the right side of the face of the display panel 
counterclockwise at the same time.

3. The security switch (called “S1” on the electronics board) is located in the upper 

left corner of the processor board, See 

 to find the location of this 

switch. While programming, the switch was on the “B” side (Program/ run mode). 

4. To save your new settings, move the security switch on the processor board to the 

“A” side (Secure/ run mode). This switch ensures your settings will be saved in 
the event of power loss.

5. Be sure to close and resecure the face of the display panel when you are finished. 

Carefully rethread the screws clockwise simultaneously.

Note: If you need to change your programming, reopen the electronics enclosure and 

unscrew the display panel to expose the processor board. Slide the security 
switch to the “B” side (Program/ run mode). Once your new selections are
