VISCOSITY SENSOR

摘要

A fluid is received into a sample tube. A processor causes an energy to be applied to the sample tube to induce vibration in the sample tube at a resonant frequency of the sample tube containing the fluid. The processor stops the supply of energy to the sample tube. The processor monitors an amplitude of the vibration of the sample tube as the amplitude of the vibrations diminish over a period of time. The processor uses the monitored amplitude to calculate an RF of the sample tube containing the fluid. The processor uses the calculated RF to calculate the viscosity of the fluid.
