EVM430-FR6047: Water Meter Constant

Hi Manos,

In the GUI, there are limitations on the meter constant value. I would suggest you to follow the instructions to get a larger meter constant value.

Best regards,

Could you please point me which instructions should I follow?

I tried this with the GUI
https://e2e.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/994698/msp-ultrasonic-design-center-msp430fr6047

But it didn't change anything to the value of the meter constant.

Could you explain how I could do this

You can set the volume scale factor(meter constant) in the USS_userConfig.h file:

#define USS_VOLUME_SCALE_FACTOR                      1.2742e7f

Change the value and update the firmware of the EVM430-FR6047 ?

Thanks in advance
