ABSTRACT:
A method and apparatus for drawing and measuring an amount of liquid agrichemical and dispensing the measured amount of agrichemical for mixture with water and eventual application onto a field. The agrichemical is drawn into a measuring vessel by suction pressure, created in one embodiment by an air compressor and valving system, and in another embodiment by a valve-pump in conjunction with a 3-way valve. The agrichemical is then dispensed from the measuring vessel either by positive pressure created by the same air compressor/valving system, or by suction pressure created by valve-pump/3-way valve. The valve-pump provides both a mixing chamber for the agrichemical and water prior to tank storage for eventual application, and controllable suction pressure for drawing the agrichemical out of the measuring vessel for mixing. The valve-pump is also self-cleaning thereby reducing the possibility of cross-contamination.
