![]() ![]() Separate display systems in indicator provide a digital read-out of average wind speed and an analog(LED) display for instantaneous wind direction and speed.ĥ.Unit of wind speed can be switched between m/s and knotĦ.Digital display updates avarage wind speed every 10 minutesħ. Both features provide increased reliability and accuracy.Ĥ.Easy-to-read Analog and Digital Displays The cups catch the wind, turning a dial attached to the instrument. Wind velocity or speed is measured by a cup anemometer, an instrument with three or four small hollow metal hemispheres set so that they catch the wind and revolve about a vertical rod. Patented non-contact system for wind measurement uses optical fiber instead of the traditional spring mechanism and the wind direction detector employs an 8-bit encoder. A WIND VANE is an instrument that determines the direction from which the wind is blowing. Wind speed detecting propeller is made of highly durable, lightweight glass fiber polycarbonate.ģ.Increased Accuracy Through Optical Technology The transmitter housing is made of plastic, reducing weight by 1/5 and overall area by 2/3 which allows for easy installation. In anemometers, the essential choice is the Marine Vane FV-301A.ġ.Compact and Lightweight. In pursuing the highest achievements in design and function, Tamaya has engineered a more compact and lightweight anemometer.Ī new compact design (2/3 smaller and 1/5 the weight of recent models), and improved function through a patented internal optical pulse system, make this wind speed and direction instrument more durable and accurate than ever before. It can be used on a wide variety of vessels – small boats, fishing boats, and work ships. ![]() This equipment shows on display the relative direction and relative speed of wind flowing above a travelling vessel. KOSHIN Marine Vanes (Anemometer) 〈FV-301A〉Īn anemometer is an equipment which measures both wind speed and wind direction, simultaneously. About Wind Speed and Wind Direction Sensors Wind vanes measure wind direction and are often used with anemometers, which measure wind speed. ![]()
