I really do apologise if this is a stupid question but I for the life of me can't find an answer. I need to do a project where I measure the liquid of water in a tank using ultrasound and am planning on doing it with Texas Instruments TDC1000.
The problem I'm having is that I can't find the ultrasonic transducers that they use in their examples in my country and was thinking I could maybe just use one similar to it. However I can only find ceramic benders. I would just like to know if they are the same and if not what is the difference.
