P-553 ABSTRACT OF THE DISCLOSURE An agricultural spraying assembly including a plurality of nozzles divided into groups with each group being supplied liquid through a solenoid valve with a motorized proportioning valve being adjustable to control the pressure supplied to the solenoid valves and, in turn, to the plurality of nozzles. The assembly includes a main control box which is normally situated on a spraying trailer and a remote control box which is normally situated on the pulling tractor and is supplied power from the tractor's battery. Each of the control boxes includes switches for each of the solenoid valves as well as a pressure adjusting switch for adjusting the pressure supplied to the nozzles. Each control box has a pressure gauge for indicating the operating pressure supplied to the nozzles. Each nozzle is supported by a nozzle body with transverse passages, one being a flow-through passage and the other being a nozzle passage with a platform having a wall common with the nozzle passage and a transducer encapsulated in a potting material for responding to vibrations of the flow through the nozzle for providing a signal to the control boxes. In the event the flow through the nozzle is insufficient, the main control box will interpret the signal from the transducer and provide an indication on both of the control boxes. Each nozzle also includes a no-drip valve associated with the inlet end of the nozzle passage for termin- ating liquid flow to the nozzle passage in the event the pressure of the liquid being supplied is below a predetermined level.
