Dear TI team,

in my application, i will use TDC1000 + transducer ( ultrasonic ) to sense the water level of a plastic container from outside.

do i have to touch the transducer (SMD10T2R111) firmly on the bottom wall of the container?

if there is small gap between transducer and the bottom wall, will this technology still work?

Regards

David Lei

    Hello David,

    Thank you for your question. In order to transmit through a tank wall the device must have good mechanical connection with the tank wall. If there is a small gap between the tank and the transducer you will not get enough energy to transmit through the tank wall in order to perform your measurements. What will happen is that most of the energy will reflect off of the tank instead and only a small portion will travel through the tank wall. So to answer your question the technology will not work if the device is not attached properly.

    You can take a look at this app note as a guide on how to mount the transducer to the bottom of the tank. I hope this helps!

    Best,

    Isaac
