where to find Ultrasonic transceiver and price

In flow metering, I saw documents on ultrasonic flow measurement. However they are all on the MSP430FR6792. I cannot find anything on the ultrasonic flow transceiver itself. I can order MSP430FR6792, but where do I obtain ultrasonic transceivers?

    Hi Graham,
    The ultrasonic transceivers are typically sold directly by the manufacturer. In some cases, you are able to place small orders of transceivers through distributors such as Digi-Key, Mouser, Farnell, etc. I have published a listing of air-coupled ultrasonic transducers at: e2e.ti.com/.../620399

    The transducers in the link above are intended to be used with the PGA450-Q1 and PGA460-Q1 devices for open-air environments, not a liquid transmission medium. However, many of these manufacturers also make transceivers for flow metering (such as Steminc and Audiowell).

    I am looping in my colleague who has more experience with ultrasonic flow metering for additional comment.

    Hi Graham,

    As Akeem said, the transducers are not supplied by TI, but rather by specific transducer manufacturers. For liquid medium applications, this application note includes some good transducer recommendations: www.ti.com/.../snaa266a.pdf

    The webench designer on the TDC1000 product page (www.ti.com/.../TDC1000-Q1) also has suggestions for flow applications.

    Regards,
