ABSTRACT:
A system for sensing a property of a fluid comprises a fluid channel operable to receive the fluid therein, a flexible arm having a free end positioned within at least a portion of the fluid channel, a fluid actuator disposed sufficiently close to the flexible arm such that actuation of the fluid actuator induces movement of the flexible arm when the fluid is present, and a deflection sensing system operable to quantifiably detect movement of the flexible arm.
