Radio travels at speed of light so pretty much instantaneous. Then program the difference between the heard radio wave and the heard ultrasonic wave to be calculated by multiplying the time it takes for the second arduino to hear the sound wave by the speed of sound in air. Gives distance. Will be a much much simpler circuit.

For ultrasonic installation, a pneumatic driver will create high-frequency vibrations. The heat generated by these vibrations will melt the plastic, allowing the ultrasonic insert to be installed and held in place by the cooling plastic. Heat drivers work by heating up the insert to a temperature beyond the melting point of the thermoplastic.

Hi Trimick, you really need to drive the piezos with a high voltage sine wave, this nearly always done using a self resonant circuit so it always finds the resonant most efficient frequency of the piezo. Using something like a 555 is liable to over heat something.

An ultrasonic sensor is a device that uses ultrasonic waves to measure an object's distance. Ultrasonic transducers — which are the microphone and speaker tandems — send and receive ultra-high frequency sound waves to obtain an object's distance or proximity.

Therefore, the goal of this project will be the study of ultrasonic generators oriented to industrial purposes like ultrasonic soldering, drilling or cutting. An ultrasonic generator is the device that provides the electrical energy to power the ultrasonic transducers. It basically generates the ultrasonic signal with the proper frequency,

All you need is the square wave driving signal. Also since these devices have a high-Q response, it is useful to be able to adjust the frequency +/- 5% around 40khz to get the sweet spot. Piezo transducers act like capacitors. Audio amplifiers are designed for loudspeakers, which are mostly inductive loads.

The power driver is typically a switching-type power amplifier, with a transformer. The water-loaded transducers do not need an exact frequency ; the resonance is wider ~5%, and efficiency, too. ...

A piezo transducer behaves somewhat as a capacitor. As your driver transistor allows only a single polarity intermittent current to flow in the transducer (with or without D1) there is no oscillation as would be required for an ultrasonic output. The transducer's capacitance simply charges up to about the supply voltage.
