MSP430FR6043: gas flow measurements

Prodigy 120 points

Replies: 4

Part Number: MSP430FR6043

GAS flow measurements are performed on a  pipe with 200-kHz, 400-kHz, and 500-kHz transducers available from Jiakang, Hurricane, CeramTec, and Audiowell.

How do different frequencies affect measurements?Which frequency has the best accuracy theoretically?

And where to download the 3D printable pipe design?

  • Hello,

    Typically, the lower frequencies such as 200 kHz give better Zero Flow Drift while the 400 & 500kHz ones offer lower standard deviations. I'm not sure if any is theoretically the best, but I think 400kHz is the most common.

    Unfortunately, I do not know of any 3D printable pipe designs available online. More information on the MSP430 Ultrasonic resources can be found on TI.com here: www.ti.com/.../overview.html

    Thanks,
    JD

  • Hi,
    Which pipe size you require based on your application. G1.6, G2.5 or G4? And what accuracy level you need? We have tested some 3D print pipe in our lab, if you can provide us your requirements, I can check if we have the exact pipe design for you.

    Best regards,

    thank you.

    I have downloaded the above pipe design from TI. 

    But I can not find the below pipe design,

    I need the below 3D pipe design , thanks.

    Hi,

    You can try this one.jk_500kHz_windowed.stl
