    • PROBLEM TO BE SOLVED: To detect a wind speed by detecting ions carried by wind.SOLUTION: A linear ventilation passage 4 is formed in a case 3. A plurality of collector electrodes 6 are arranged in a line while facing the ventilation passage 4. A repeller electrode 7 is arranged with facing the collector electrodes 6. An ion generator 5 is arranged on one side of the ventilation passage 4. Ions generated by the ion generator 5 flow in the ventilation passage 4 by wind, and are collected by the collector electrodes 6. The amount of ions collected by each of the collector electrodes 6 differs according to the wind speed. A detection unit 2 detects an ion distribution along the wind flow direction based on detection signals from the collector electrodes 6, and obtains the wind speed from the ion distribution.

    • PROBLEM TO BE SOLVED: To provide a flow rate measuring apparatus capable of correct measurement of the flow rate of liquid without contact, a generating device of a temperature distribution within liquid for measuring flow rates, and a measuring method of a flow rate. SOLUTION: The flow rate measuring apparatus 100 includes a light source 12 for exciting light which is connected to a modulator 14 and irradiates exciting light into liquid in the channel 11; a light source 13 for detecting light which irradiates liquid at downstream of the channel 11 with detecting light; a generating device 1b of a temperature distribution within liquid, which is connected to the light sources 12 and 13; and a receiver 1c for detecting temporal variation of detected light through its reception. The generating device 1b of a temperature distribution within liquid is composed such that a spacing d' in the longitudinal direction of channel 11 between the irradiated position of exciting light and irradiating position of detecting light within liquid is a predetermined range. The flow rate measuring apparatus 100 computes the time Δt from modulation onset/end time of modulator 14 and the signal strength I max of detecting light and thus the flow rate v is computed from the spacing d' and the time Δt.
