  • Page 7: Introduction

    The clamp-on sensors are attached to the outside of the pipes. The KATflow 230 uses ultrasonic signals for the measure- ment of the flow, employing the transit-time method.

  • Page 8: System Configyration

    KATflow 230 2 Introduction 2.1 System configuration A maximum of 2 sensor pairs can be installed - if two pairs are installed these can be configured either in a 1-pipe dual-path or a 2-pipe single path configuration. Illustration 3: KF230 in a 1 pipe 2 path configuration...

  • Page 10: Clamp-On Sensor Installation

    KATflow 230 3 Installation 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).
  • Page 11 KATflow 230 3 Installation For a free inlet or outlet pipe section: Select the measuring point at a location where the pipe cannot run empty. 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.

    KATflow 230 3 Installation 3.4 Pipe preparation Clean dirt and dust from around the area of the pipework where the ● sensors are to be placed. Remove loose paint and rust with a wire brush or file. ● Firmly bonded paint does not necessarily need to be removed provided the flow- meter diagnostics indicate sufficient signal strength.

  • Page 17: Correct Positioning Of The Sensors

    KATflow 230 3 Installation 3.7.3 Correct positioning of the sensors Illustration 8: 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 18 KATflow 230 3 Installation 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.
