Abstract
A flow rate-velocity sensor device includes a package including a light receiver and a light emitter, a transparent substrate including a light shield, and a flow rate-velocity calculator. The flow rate-velocity calculator includes a receiver, a correction unit, an arithmetic unit, and a transmitter. The receiver receives data on a first power spectrum. The correction unit corrects the data received by the receiver to calculate a second power spectrum. The arithmetic unit calculates at least one of a flow rate or a flow velocity from the second power spectrum calculated by the correction unit. The transmitter transmits, to an external unit, at least one of the flow rate or the flow velocity calculated by the arithmetic unit.
