摘要
Thickness-shear mode resonators which simultaneously measure mass depositionand fluid properties can be utilized to monitorpetroleum processing, petrochemical and water treatment systems. Specialtychemical additive materials can be accurately andinstantaneously added to control conditions detected by the thickness-shearmode resonators. The thickness-shear mode resonators arepiezoelectric crystals used in conjunction with oscillator circuitry that candetermine mass as well as viscosity and/or density of a fluid incontact with the piezoelectric surface.
