FS-012 Non intrusive flow switch Flow switch with clamp-on transducers able to use in non-invasive liquid measurement. Microprocessor based, user friendly, field programmable flow measurement technique allows no interruption of the process flow and has low installation cost  2 line LCD display with flowrate  Wide range velocities of 0,02 to 12 m/s  Transducers pipe size from 20 to 3000 mm  Alarm led indication Measuring conditions Transit time principle TTP utilizes a pair of ultrasonic transducers which are mounted on the pipe upstream and downstream respectively. Each transducer functions as both ultrasonic transmitter and receiver. The main unit operates by alternately transmitting and receiving a coded burst of sound energy between the two transducers. The transit-times in the upstream direction as well as in the downstream direction are measured. The difference of the two transit times is directly and exactly related to the velocity of the liquid in the pipe, Fluid types Virtually all commonly used clean liquids with small quantity of tiny particles up to concentration < 10000 ppm and particle size less than 80 µm. Liquid must to be free of bubbles and turbulences Pipe conditions Pipe material can be all metals, plastics, fiber glass, etc. , quite all of homogeneous pipes. Allow pipe liner. Pipe straight run must to be 15 or 30 times pipe diameter as minimum free straight pipe to warranty minimum turbulences.
