I want to design a non-invasive ultrasonic flow sensor. It will be used in the medical field. It will calculate the flow rate of blood flowing through a silicone tube. A circuit will be designed. The piezoelectric sensors used will have a frequency of around 2MHz. The tube will have a diameter of 0.5 inches. The sensor will enter the tube non-invasively by compressing it. This will be done in a microcontroller architecture with 16-bit ADC resolution. There will be 4 piezoelectric sensors, and 2 piezoelectric sensors will take measurements in pairs, one on each side. Piezoelectric sensors will be positioned at a 45-degree angle.

Welcome to your new project. Imagine what you can build here.
