An electronic device that monitors flow of a fluid in a vessel (such as a pipe) is described. This electronic device may be mounted on an exterior of the vessel using a mounting mechanism. For example, the mounting mechanism may be attached to the vessel using a clamp, and an impedance-matching material may provide mechanical coupling to the vessel. Moreover, during operation a sensor mechanism in the electronic device may measure flow of the fluid, and an integrated circuit in the electronic device may analyze the flow measurements. In particular, the sensor mechanism may measure flow using non-invasive techniques (e.g., using an ultrasound transducer, an acoustic sensor or a vibration sensor) without contact with the fluid. The sensor mechanism may also facilitate the analysis by determining an orientation of the sensor mechanism relative to a reference direction and/or a cross-sectional area of the flow. |
