Method and system for analyzing a gelation reaction by utilizing a piezoelectric resonator
 A viscosity measuring system comprises a cell containing gelable liquid and a piezoelectric resonator mounted in the cell. The piezoelectric resonator has a prescribed characteristic, such as electrical resistance or resonant frequency, which varies in accordance with the gelating of the liquid. Solid particles suspended in the liquid are deposited on the piezoelectric resonator during gelating of the liquid to amplify the prescribed resonator characteristic. A measuring circuit measures the variation of the resonator characteristic to thereby determine the gelation time of the liquid.
