Tool/software:
I am using MSP430FR6043 to measure water flow using an 8mm diameter tube.
I captured images of signals when there is no flow.
I expected the peak to be in the middle of the received signal. but I can see a peak at the front of the received signal.
I'm unsure if my measured signal is normal.
Additionally, I can see that the 6th pulse is a peak in the left image, and the 5th pulse is a peak in the right image. This seems to cause variation in Delta TOF.
How can I make the received signal look like a clean envelope signal?
