1.3 Flow measurement principle
The TFUF-TTCL 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 TFUF-TTCL 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 Wmethod
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: 
 

1.4 Optional transducer 

 TS-1 clamp-on type transducer, pipe size from DN15-100mm 

 TM-1 clamp-on type transducer, pipe size from DN50-1000mm 

 TL-1 clamp-on type transducer, pipe size from DN300-6000mm 

 HTS-1 clamp-on type transducer, pipe size from DN15-100mm (high temperature) 

 HTM-1 clamp-on type transducer, pipe size from DN50-1000mm (high temperature) 

 HTL-1 clamp-on type transducer, pipe size from DN300-6000mm (high temperature) 


1.5 Typical application
The wall-mounting flow meter can be applied to a wide range of pipe flow measurements. Applicable liquids
include pure liquids as well as liquid with small quantity of tiny particles. 
Examples are:
 Water (hot water, chilled water, city water, sea water, waste water, etc.);
 Sewage with small particle content;
 Oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.);
 Chemicals (alcohol, acids, etc.);
 Plant effluent;
 Beverage, liquid food;
 Ultra-pure liquids;
 Solvents and other liquids
