Assignee: FLUIDINSIGHT LTD.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 3:
4. A fluid sensor, comprising:
a microcontroller;
a sensing unit communicatively coupled to the microcontroller, the sensing unit including a driving element and a sensing element, the sensing unit further comprising:
a fluid conduit;
a first bobbin surrounding the fluid conduit and at least one first coil disposed on the outer surface of the first bobbin;
a second bobbin surrounding the at least one first bobbin, and at least one second coil disposed on the outer surface of the second bobbin;
a magnetic shield surrounding the second bobbin; and
a bobbin assembly sleeve enclosing the magnetic shield, first bobbin, and second bobbin;

wherein the microcontroller generates a signal to excite the driving element of the sensing unit and receives a signal from the sensing element of the sensor so as to perform a measurement of a complex impedance of a fluid;
wherein the sensing unit is adapted to perform the measurement, the measurement being a magnetic induction spectroscopy (MIS) sweep of the fluid; and
wherein a property of the fluid is determined based on the measurement, the property being an electromagnetic induction fingerprint of the fluid, based on impedance exhibited due to inductance of particles in the fluid, collected over the MIS sweep.
