DROP AND DRIP MEASUREMENT
First Claim
1. A method for calculating a volume of an individual falling drop of liquid by analyzing electromagnetic radiation (EMR) reception, said method comprising:
- projecting electromagnetic radiation (EMR) from an EMR source;
measuring said EMR using at least one EMR sensor when said EMR is partially interfered with by a drop falling between said EMR source and said EMR sensor;
calculating a plurality of widths parallel to a vertical axis of said drop, each one of said plurality of widths is calculated according to a reception of a time correlated measured portion of said EMR; and
calculating a volume of said drop by combining said plurality of widths and a velocity of said drop when said drop is falling between said EMR source and said EMR sensor.
