Abstract
A flow rate meter comprises a disposable fluid transport portion and a reusable interface connector removably attached to the transport portion. The transport portion includes a flow conduit having an input and an output, while the interface connector provides feedback to a desired location. First and second portions of control circuitry are, respectively, associated with the transport portion and the interface connector. The first circuitry portion includes a plurality of electrodes and derives flow rate. The device measures a range of flow rates and is adapted, for example, for use in micro-fluidic systems including fluids administration to a patient's body.
