Operation Manual
The document includes analysis and discussion of the sources of error/measurement eects due to:
Balance system calibration.
Absorbing (or reecting) target suspension mechanisms.
Linearity of the balance system.
Extrapolation to the moment of switching the ultrasonic transducer (compensation for ringing
and thermal drift).
Target imperfections.
Absorbing (reecting ) target geometry and nite target size.
Target misalignment.
Ultrasonic transducer misalignment.
Water temperature.
Ultrasonic attenuation and acoustic streaming.
Coupling or shielding foil properties.
Plane-wave assumption.
Environmental inuences.
Excitation voltage measurement.
Ultrasonic transducer temperature.
Eects due to nonlinear propagation and saturation loss.
The overall ndings of the analysis give a rough Acoustic Power accuracy gure of +/- 10% for the
frequency range of 1 - 10 MHz.
