AWR1443: Water level measurement up to 5m with cm or mm accuaracy

Part Number: AWR1443
Other Parts Discussed in Thread: AWR1642,

I wonder if it is possible to use AWR1443 or AWR1642 as distance measurement 0-5m or similar, with cm or mm accuracy for measuring water/waste water levels?

In this case having an analog output (0-3.3V, 0-5V or 4-20mA from EV board will be great)

Hmm - can it be used for flow speed measurement, too? May be not.

Any ideas?

    Hello ,

    The TI mmwave devices are capable of measurement accuracy of close to about 0.1mm.

    I think you're going to be very interested in our TI Design for level sensing with a power optimization scheme. You can find an overview with all necessary documentation here:

    Below post already has answered your queries:

    Thanks,

    Thanks Raghu,

    one more - when I purchase mmWave dev.kit  with 1443, it can be used for both "normal" distance and accuracy and "high precision", BOOST without change/modify

    hardware on the board (or with simple one)? Is there also different antennas, etc.

    Thanks again,

    Dimitar

    Hi Dimitar,

    For this kind of measurement you are going to want to use the High Accuracy Lab for xWR1443, available on the TI Resource Explorer (dev.ti.com/.../

    With this demo you should find much better than cm accuracy out of the box. With a precision mount, tank, and setup you can improve the accuracy to better than 5 mm with most measurements being better than 2 mm.

    Variations are also possible in the chirp configuration but these variations have not yet been tested.

    Let me know if you have any more questions at this time.


    Cheers,
    Akash
