Abstract:
A disposable fluidic sensor module for an apparatus for analyzing a fluid, the disposable fluidic sensor comprising:a plate-like member having an inlet adapted to receive a flow of the fluid and an outlet for exhausting the flow of the fluid;a fluidic flowmeter formed in said plate-like member in a path between the inlet and the outlet, said fluidic flowmeter being responsive to the flow of the fluid to generate an output indicative of a flow rate of the fluid;a capillary structure formed in said plate-like member in a path between the inlet and the outlet, said capillary structure restricting a flow of the fluid such that a pressure drop across said capillary structure is related to a viscosity of the fluid; anda sonic oscillator formed in said plate-like member in a path between the inlet and the outlet, said sonic oscillator generating flow oscillations having a frequency related to the specific heat of the fluid.
