    3 Installation KATflow 210 3.2 Clamp-on sensor installation The correct selection of the sensor location is crucial for achieving reliable meas- urements and a high accuracy. Measurement must take place on a pipe in which sound can propagate (see Acoustic Propagation) and in which a rotationally sym- metrical flow profile is fully developed (see Straight Pipe Lengths).

Correct Disadvantageous Correct Disadvantageous For a vertical pipe: Select the measuring point at a location where the liquid flows upward to ensure that the pipe is completely filled.

    3 Installation KATflow 210 3.7.3 Correct positioning of the sensors Illustration 6: Correct positioning of the sensors Mount the transducer pair so that the front edges of the sensors (opposite the cable entry) face each other. There is a different engraving on the top of each transducer. The transducers are mounted correctly if the engravings on the two transducers form an arrow.
  • Page 17 3 Installation KATflow 210 Place the transducer on the side of the pipe or alternatively up to 45 de- ● grees from the horizontal plane through the pipe. This is advisable to establish the best acoustic contact since on top of the pipe air pockets could develop and deposits could accumulate at the bot- tom of the pipe.
