Measurement of the Viscosity-Density Product Using a Quartz Wedge
Conference
·
OSTI ID:15020096
The on-line measurement of the viscosity-density product is accomplished by analyzing the multiple reflections of an ultrasonic shear horizontal (SH) wave within a quartz wedge. Many echoes are observed as the ultrasound is reflected from the two sides (inclined at a 70{sup o} angle) and the quartz-liquid interface at the base of the wedge. The analysis yields a very accurate measurement of the reflection coefficient. The measurement is self-calibrating because it is not affected by changes in the pulser voltage.
