1.4. Principle Of Measurement
Our ultrasonic flow meter is designed to measure the fluid velocity of liquid within a
closed conduit. The transducers are a non-contacting, clamp-on type, which will
provide benefits of non- fouling operation and easy installation.
The transit time flow meter utilizes two transducers that function as both ultrasonic
transmitters and receivers. The transducers are clamped on the outside of a closed
pipe at a specific distance from each other. The transducers can be mounted in
V-method where the sound transverses the pipe twice, or W-method where the
sound transverses the pipe four times, or in Z-method where the transducers are
mounted on opposite sides of the pipe and the sound crosses the pipe once. This
selection of the mounting method depends on pipe and liquid characteristics. The
flow meter operates by alternately transmitting and receiving a frequency
modulated burst of sound energy between the two transducers and measuring the
transit time that it takes for sound to travel between the two transducers. The
difference in the transit time measured is directly and exactly related to the velocity
of the liquid in the pipe.
