Hi,

Can i know what is the current acoustic length that the program runs in the latest water demo application.

Hi Divya,

The L is length of acoustic path between two transducers. L is included in volumeScaleFactor in USS_Meter_Configuration structure, namely Meter Constant in USS Design Center parameters page.

The equation between Meter constant and acoustic length L

Hi Winter,

Unfortunately i haven't got a clear idea about how volume is calculated using this equation .

It would be great help if you could tell me where in the code is the calculation for volume implemented.

Best Regards,
Divya

Hi,

The volume is calculated by below equation:
volume = meter constant*dTOF/(UPS_TOF*DNS_TOF).
meter constant is the part circled by red in above picture.
