Abstract: A fluid sensor device for measuring properties of a fluid is disclosed. The fluid sensor device includes a leaf cell sensor having a piezoelectric structure acting on a subdomain of the fluid that flows through the piezoelectric structure to create an intrinsic Helmholtz cavity response, and an enclosure enclosing the leaf cell sensor and including (i) a flowthrough shroud having an inlet that allows the fluid to enter the enclosure and pass across the leaf cell sensor, and a Helmholtz cavity wall that couples the intrinsic Helmholtz cavity response with an external acoustic field of the leaf sensor to increase a measurement sensitivity, (ii) a cylindrical housing having an outlet that allows the fluid to exit the enclosure, and (iii) a pressure feedthrough connector that transmits an electrical signal induced by the intrinsic Helmholtz cavity response to represent the properties of the fluid.

Abstract: An apparatus for fluid measurement is disclosed. The apparatus includes a leaf cell sensor having one or more piezoelectric radial components connected to a circumferential component, a first electrode positioned on a distal face of at least one radial component, a second electrode positioned on a proximal face of the at least one radial component, a voltage source having a negative terminal and a positive terminal, the negative terminal being connected to the first electrode and the positive terminal being connected to the second electrode, an electric current measurement device connected to the first and second electrode to measure current flowing between the first and second electrode, and a processor of a computing device that determines, from the measured current, one or more properties of the fluid, where the voltage source couples electrical energy into the one or more piezoelectric radial components at multiple frequencies concurrently.
