Supply tube assembly for monitoring a directed stream measuring the liquid of an agricultural product application rate through a supply tube

A method for measuring a liquid agricultural product application rate of liquid agricultural product flowing through a supply tube, comprising:

• a) providing a supply tube assembly of the type comprising:
• a sensor body assembly incorporated in said supply tube, comprising:
• i. a sensor body having a sensor inlet end positioned to receive an inlet flow of said liquid agricultural product from said upstream portion and a sensor outlet end positioned to receive an outlet flow of said liquid agricultural product, said sensor body being an enclosure having a cross sectional area larger than the cross sectional area of said upstream portion of the supply tube and said downstream portion of the supply tube, said sensor body being configured and constructed so that the liquid agricultural product does not come in contact with an inside surface of the enclosure while flowing from the sensor inlet end to said sensor outlet end;
• ii. a first sensing plate located on a first operable position of said sensor body;
• iii. a second sensing plate located on a second operable position of said sensor body opposite said first sensing plate;
• iv. electronic sensing components operably connected to said first sensing plate and to said second sensing plate configured to measure the liquid agricultural product application rate between said first sensing plate and said second sensing plate;
• and,
• b) flowing liquid agricultural product through said sensor body assembly;
• and,
• c) measuring the liquid agricultural product application rate between said first sensing plate and said second sensing plate utilizing said electronic sensing components,
• wherein the cross sectional area of the upstream portion outlet end of the supply tube is sufficiently large so that the liquid agricultural product builds up on said upstream portion outlet end and falls off due to gravity as a drip, said sensor body being oriented substantially vertically, wherein said enclosure is hollow.
