MSP430FR6043: MSP430FR6043 gas flow detection

Part Number: MSP430FR6043

Hi Team,

There's an issue from the customer need your help:

I saw the calculation of volume flow in the official program, but I couldn't find the parameters for setting the pipe cross-sectional area in the program or in the GUI host computer software? Where is this parameter defined or stated? Where are the parameters of the distance between the two ultrasonic sensors set?

I found out in the official routine that there is something wrong with the flow rate calculation formula:

Is there something wrong with the program?

Best Regards,

Ben

    Hi Ben,

    The iq16Velocity is the sound velocity. In the document, the v is velocity of gas/water flow. 

    We are not implementing the estimate temperature function in gas meter project. So, you could not find the definition. In water meter project, it is defined in  USS_temperatureLUT.h. 

    Best regards,

    Cash Hao
