PROBLEM TO BE SOLVED: To provide a compact anemometer device with reduced acoustic noise which enables highly accurate measurement of wind direction and velocity.SOLUTION: An anemometer device 100 includes a housing 4 with a flow channel section 6 for a measured fluid 2 to flow formed therein and a pair of ultrasonic transceiver units 1A and 1B, each mounted at a predetermined tilt angle with respect to the flow channel section 6, and is designed to measure wind direction and velocity of the measured fluid 2 on the basis of propagation time of an ultrasonic wave transceived between the pair of ultrasonic transceiver units 1A and 1B. A pair of separate fixing plates 51 and 52 is provided with a space therebetween along an axial direction of the flow channel section 6 to fix the pair of ultrasonic transceiver units 1A and 1B onto the housing 4. The effect of acoustic noise is reduced by attaching each of the pair of ultrasonic transceivers 1A and 1B to each of the pair of the separate fixing plates 51 and 52 with an anti-vibration member 20 for preventing transmission of vibration therebetween. |
