摘要: An apparatus for determining a fluid's kinematic viscosity from ultrasonic energy that has passed through the fluid of unknown along an acoustic path known length. A computer determines characteristic frequency received electrical signal associated with and measures velocity sound. The is determined by on continuous basis based sound velocity. method viscosity.
