I dont want an ultrasonic transducerThere are many different kinds ultrasonic transducers and drivers available for different applications. You can get them for ultrasonic cleaning, liquid level measurement, under water fish finding (sonar), distance measuring, etc. What exactly do you want to do with it?
A piezo element is a transducer.I dont want an ultrasonic transducer
Level of what?for level sensing
yesAre you trying to make an ultrasonic distance sensor? To install in a tank, looking down at a liquid to determine the volume of said liquid in said tank?
Yes, it is possible. There are many tutorials on the internet on how to do it very easily and inexpensively using an Arduino microcontroller and a HC-SRO4 ultrasonic sensor. If you really want to make your own sensor using ceramic transducers, that will be much more complicated. What is your level of expertise in designing analog and digital circuits? Are you familiar with the physical properties of ceramic transducers?I dont want an ultrasonic transducer
I want to generate ultrasonic by piezo elements for level sensing
Im trying to make ultrasonic sensor
is it possible ?
No more than 30cmHow far from the liquid surface will the measuring device be? (There are cheap distance sensors widely advertised on the web, but they have a specified minimum range).

Then the HCSR04, as suggested by Keith, would seem to provide a ready-made solution. It would also be cheaper than trying to build a similar device yourself.No more than 30cm
Then I highly recommend that you use an Arduino with the HC-SRO4 ultrasonic sensor. It is small and inexpensive and is also accurate and reliable. It would take you a very long time to gain enough knowledge and expertise to design your own.I'm not experienced at piezoelectric ceramic transducers case but I'm experienced at Arduino and programming and a little experience in electronics
