  • Page 7: Introduction

    The clamp-on sensors are simply attached to the out- side of pipes. The KATflow 230 uses ultrasonic signals for the measurement of the flow, employing the so-called transit-time method.

    The following items are typically supplied (please refer to your delivery note for a detailed description of your scope of supply): ● KATflow 230 portable flowmeter ● Clamp-on sensors (usually one or two pairs depending on pipe sizes to be measured) ●...

  • Page 9: 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 10 KATflow 230 3 Installation Correct Disadvantageous For a vertical pipe: Select the measuring point at a location where the liquid flows upward to insure that the pipe is completely filled. Correct Incorrect Table 1: Recommendations for sensor mounting location Look for a sensor installation location with sufficient straight pipe to obtain accurate measurements.

    KATflow 230 3 Installation 3.5 Clamp-on sensor mounting configurations and separation distance Reflection Mode The most common clamp-on sensor mounting configuration is the Reflection Mode, also known as V-Mode (see Illustration 3, sketch (1). Here the ultrasonic signal pass twice through the medium (2 signal passes). The Reflection Mode is the most convenient mounting method as the transducer separation distance can be meas- ured easily and the sensors can be perfectly aligned.
