In ultrasonic level transmitter, a ultrasonic source is
used to produce ultrasonic pulses . these pulses are
transmitted through the vessel,the echo returning back
from the vessel is then recieved by a detector , depending
upon the level in the vessel the frequency of the recieved
signal varries ,the difference between the transmitted
pulse frequency and the recieved signal frequency is used
to measure the level.
