i need to measuring the flow rate in a water pipe with 640mm of diameter and the velocity is 3 m3/s. I was thinking to use the Pitot metod to measuring the flow rate. I can use the ultrasonic but i don't know anything about it. And i'll use Atmega8 to pick the information from the sensors and display then in a LCD. Someone could help me or give me some tip about this.
Thanks.
