An ultrasonic transmitter is being used to measure liquid level in a process vessel. The liquid level in the vessel is 2.8 m. If the transit time of the ultrasonic signal from the sensor to the liquid surface and its return is 8.3 ms, calculate the distance from the sensor to the bottom of the vessel. The velocity of sound through the medium is 342 m/s.
what will be the answer, which equation needs to be used?

Lovely…Good Animation.
WONDERFUL Post.thanks for share..more wait .. …
Thanks for sharing your knowledge.
This is one awesome post.Really thank you!

Distance = speed of sound x Td/2 = 342 m/s x 8.3 ms / 2 = 342 m/s x 8.3 x0.001/2 = 342 m/s x0.00415 = 1.42 m
Tank height = liquid level + distance = 2.8m + 1.42 m = 4.22 m
