Abstract
PURPOSE:To obtain a window direction/velocity meter having no driving part and capable of measuring window direction and velocity simultaneously, by arranging a plurality of window ducts of a hot-wire type velocity meters radially at a constant angular pitch around a vertical axis. CONSTITUTION:A plurality of hot-wire type window velocity meters have ducts 1 to 4 each of which being provided at its central portion with a heater and at its both end portions with thermistors. Air velocity in the duct, i.e. the window velocity, is detected from the temperature differential between the air inlet side and air outlet side of the duct. It is also possible to detect the direction of flow of air in the duct. These ducts are arranged radially at a constant angular interval around an axis which is perpendicular to the plane of the sheet. According to this arrangement, the actual window direction and window velocity can be detected by composing the signals representing the window velocity and direction from all ducts.
