Patent Images
1. A device for measuring a continuous flow rate of an air stream comprising:
- a fluidic oscillator;
a nozzle to direct a portion of the airstream into the fluidic oscillator;
a detachable mouthpiece to reduce back pressure within the device, wherein the detachable mouthpiece defines a plurality of channels, at least one of the plurality of channels directs the portion of the airstream to the nozzle and at least one other channel vents another portion of the airstream to an environment external to the device;
the fluidic oscillator having a housing and at least one obstacle, to induce oscillations in the airstream, wherein a frequency of the oscillations correlates to the continuous flow rate of the airstream; and
at least one sensor to measure the oscillations of the airstream, the at least one sensor to generate an electronic signal corresponding to the oscillations measured and transmit the electronic signal to a computing device.
