Liquid viscosity measuring and regulating method; compares signal energy and amplitude required to maintain resonance frequency of vibration measuring element suspended in liquid with known viscosity characteristics

摘要

The method involves using a vibration measuring element suspended in the liquid, with measurement of the energy and amplitude of the signal required for maintaining the resonance frequency of the measuring element, to determine the viscosity using characteristics obtained for liquids of known viscosity and to provide a signal for regulating the viscosity.
