1.3 Flow measurement principle 

The TUF-2000F 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 TUF-2000F 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, show as follows:
