  • Page 41: Instrument Mounting - Open Channels

    Manual – Starflow QSD Model 6527B and 6537A Use a small pilot drill bit (about 2mm), then finish with the 5mm bit. When drilling stainless steel, use a slow speed and high pressure. Avoid stopping as the material will work harden, making it more difficult to drill. 4.
  • Page 42 Manual – Starflow QSD Model 6527B and 6537A Where possible, the cable to the instrument should be run back behind the instrument for several meters to minimise the effect of debris caught in the cable on the measurement. Appropriate shielding or conduit should be installed to protect the cable from damage. Care should be taken when selecting the site.

  • Page 43: Instrument Maintenance

    Manual – Starflow QSD Model 6527B and 6537A 7. INSTRUMENT MAINTENANCE The Starflow QSD requires very little maintenance. During routine site visits, the following checks can be performed: Piezo element Clean the instrument surfaces where the Piezo elements are faces located by wiping them with a cloth.

  • Page 44: Factors Affecting Flow Measurement Accuracy

    Manual – Starflow QSD Model 6527B and 6537A 8. FACTORS AFFECTING FLOW MEASUREMENT ACCURACY Starflow QSD measures velocity to an accuracy of ±2% and depth to ±1% of the range. This is logged to a resolution of 1 mm/sec and 1mm respectively. The purpose of the Starflow QSD system is to produce velocity data.

    Manual – Starflow QSD Model 6527B and 6537A 10.5. Overview of Creating a Flow Scheme Creating a Starflow QSD Scheme for flow measurement is a five-step process: Determine the dimensions of the channel. For open channels, create a Cross-Sectional Area in the Flow extension instrument which has already been added in the scheme editor and enter the parameters of your channel.
  • Page 62 Manual – Starflow QSD Model 6527B and 6537A The table type can also be a pipe; in this situation the pipe dimensions should be entered. In the case of a User Defined Area Rating Table, select the text file to be used. Once this has been completed then Save the Scheme.

  • Page 63: Creating An Area Rating Table

    Manual – Starflow QSD Model 6527B and 6537A 10.5.1. Creating an Area Rating Table To calculate Flow, Starflow QSD uses a lookup table called the Area Rating Table. The Area Rating Table is automatically generated when the scheme is saved from information provided in the Flow extension instrument.

  • Page 100: Inherent Factors In Doppler Histograms

    Manual – Starflow QSD Model 6527B and 6537A In fast turbulent water, the peak can be 500 mm/sec or wider because of the range of velocities present in eddies and swirls. The following histogram is typical. 17.3. Inherent Factors in Doppler Histograms The width and shape of the peak displayed are caused by a range of factors, all of which are measured by the Doppler as a frequency shift.

    Manual – Starflow QSD Model 6527B and 6537A 17.9. Measuring Unexpected Velocities In some cases, signals are from the wrong targets. A waving weed, aquatic animals, a strong stationary reflector in the bed, slow-moving saltation targets or ripples on the surface can all produce Doppler shifts that are not directly related to the water velocity.

    Manual – Starflow QSD Model 6527B and 6537A 17.10. Measuring Turbulent Velocities In higher bed slope streams, wide and multiple peaks may be displayed because of the complex moving landscape presented to the Starflow QSD. The fact that many repeats of similar velocity histograms are seen indicates that the different velocity components seen are valid.
