Abstract

A new method of measuring the viscosity of liquid, using a triangular bimorph transducer, has been proposed and has been successfully used for measuring the viscosity of various liquids over a wide range of viscosities. This viscometer is a vibration type and consists of a triangular bimorph transducer and a small circular plate. The bimorph is effectively used for both as a driving transducer and a detecting transducer, and the viscosity of liquid can be gotten by measuring the electrical phase difference between both transducers. It was found out that the phase difference of the triangular bimorph transducer appeared largely in the off-resonance frequency band, and so the viscosities of various liquids were measured by using this bimorph. This viscometer is simple in the operation and is expected to have a high accuracy.
