Chemical treatment monitoring and control of petroleum, petrochemical products and on-line correction microbalance sensor |
| abstract |
Dichnis-shear resonators that simultaneously measure mass deposits and fluid properties can be used to monitor petroleum treatment, petroleum products and water treatment systems. In particular, chemical additives can be added precisely at the same time to control the conditions detected by the declining-shear resonators. Dichnis-shear resonators are piezoelectric crystals used in connection with oscillating circuits capable of measuring the viscosity and / or density as well as the mass of fluid in contact with the piezoelectric surface. |
