measured transit time, as its name implies, measures the time difference between emission pulses travel to and against the current. This type of device is the flight time and time travel.

Each sensor in turn transmits and receives bursts of ultrasonic energy, the delay in the upper vsdownstream (TU - TD), are used on the same itinerary tailored to calculate the flow through the pipe:
