Transit time difference: V method
Principle
Sensor 1 Sensor 2
Flow
A pair of sensors aligned on the outside
wall of a pipe. The sensors emit ultrasonic pulse in turn, and detect the transit time difference of the pulse, by which
the fl ow rate is calculated.

A pair of sensors installed on the outside wall of a pipe, facing each other
slantingly. The sensors emit ultrasonic
pulse in turn, and detect the transit time
difference of the pulse. This method is
used mainly when the V method is not
available due to the space limitation, or
when the fl uid has high turbidity.
Pulse doppler method: for real-time fl ow pro le analysis
Sensor 1
Air bubbles
Sensor 2
velocity
The frequency of ultrasonic pulses refl ected by air bubbles or solid particles
changes according to the fl ow velocity.
The pulse doppler flowmeter uses this
frequency shift to determine the flow
velocity pro le.
