  • Page 9: Overview

    Overview Overview FLUXUS ADM 6725 is a flowmeter that uses ultrasound to measure the flow in closed pipes or conduits. FLUXUS can measure volume flow, flow velocity or mass flow of liquids within a temperature range from -30 °C up to 130 °C. With specially designed high temperature transducers, the temperature range can be extended up to 250 °C, and for short periods...

  • Page 11: Functional Description

    Functional Description 1 Functional Description 1.1 Measuring Principle FLUXUS utilises ultrasound for the measurement of liquid flow, employing the so-called transit time method. The instrument measures the drift of ultrasonic signals resulting from their travel through the flowing liquid. The ultrasonic signals are transmitted alternatively with the direction of flow and against it.
  • Page 12 Functional Description no dependency on electrical parameters of the fluid such as conductivity or dielectric constant. With FLUXUS, flow values can be determined immediately, in a non-invasive manner from the outside of pipes, and without interruption of the process. Mounting of the trans- ducers is straightforward, so that flow measurements can be made at various locations in the plant and on pipes with different diameters.

  • Page 40: Sound Velocity

    Program Branch PARAMETER 4.3.1 Sound Velocity FLUXUS uses the sound velocity of the medium for the calculation of the transducer distance at the beginning of the measurement. However, the sound velocity does not influence the measuring result directly. Often, an accurate value of the sound velocity for a given medium is unknown as, to a great extent, the sound velocity depends on the medium temperature.

  • Page 41: Medium Temperature

    Program Branch PARAMETER 4.3.4 Medium Temperature FLUXUS uses the medium temperature for correcting the sound velocity and the viscosity which both depend on temperature. However, the medium temperature has no direct influence on the measuring result. Enter the medium temperature within the operating range of the transducer.

It guarantees that the sound signal will be received under optimum conditions and evaluated correctly. Because of the variety of applications and factors influencing measurement, there can be no standard solution for the positioning of the transducers.

    Program Branch MEASURING However, the increased transit distance for the sound also leads to a higher attenuation of the signal in the flowing medium. Furthermore, the reflection on the opposite pipewall causes additional amplitude losses of the sound signal. It is always advisable to select the reflection mode if the pipe is sufficiently sonically Note: conductive and the pipewall is relatively smooth.
