Abstract

A sensor apparatus and a method of operating the sensor apparatus can include one or more sensors and a circuit board, wherein the one or more sensors can include a rotatable component (e.g., pulse disk, crank, pin, shaft, etc), and an angular circuit board assembly that maintains the circuit board in an angular position with respect to the rotatable component in an arrangement that allows the rotatable component to dive through the circuit board. The sensor can be, for example, a magnetic sensor, a light emitting diode or a photo diode. The sensor apparatus can include a flow channel and the rotatable component can oscillate to provide a measurement of a flow of fluid through the flow channel. The sensor apparatus can be used for the mechanical/electrical detection of pulses of a rotary motion.
