Abstract:
Pluviometric device for measuring the diameter of liquid droplets passing though a measuring space, comprising:a) optical emission means for emanating light; b) reception means for receiving light emanating from said optical emission means after said light has passed through said measuring space, wherein said reception means comprises: i) a first sensor that produces a first output signal in response to receiving a first portion of said light, and ii) a second sensor that produces a second output signal in response to receiving a second portion of said light; wherein the passage of a droplet through said first and said second portions of light results in a change in luminous intensity at said first and said second sensors, and wherein said first and said second output signals change their values in correspondence with said change in luminous intensity; and c) processing means for processing said output signals, wherein said processing means determines the diameter of said droplet by correlating said first output signal and said second output signal.
