1Measurement precision
If additional sensors are used to determine fluid viscosity, then measurement capability is improved, but device complexity and cost increase
Solution Approach 1:
The existing sensor assembly is made multi-functional by enabling it to measure both standard fluid properties and viscosity through analysis of energy dissipation characteristics. The same sensors that measure displacement are used to detect viscosity by analyzing how the fluid affects the vibrational energy of the sensor assembly, eliminating the need for dedicated viscosity sensors.
Solution Approach 2:
The sensor assembly serves itself by using its own vibrational response characteristics to determine viscosity. The system measures how the fluid influences the energy dissipation of the sensor assembly's vibration, allowing the existing hardware to provide viscosity measurement without requiring external or additional sensing elements.
