Hi team.
Our customer testing the flow detection function with our EVM board and JiaKang ultrasound transducer. They have meet below questions.
1. The value of Absolute TOF is unstable and sometime fall to 0 when no flows through the tube. What is the reason for that? Is there any suggestions to solve it?
2. the echo acquired from the signal is small, is there any method to improve it?
Thanks a lot
Matthew
