DEVICE FOR AUTOMATED CONTROL OF WORKING FLUID FLOW RATE IN BOOM-TYPE SPRAYERS Russian patent published in 1994 - IPC

Abstract RU 2020818 C1

FIELD: control equipment. SUBSTANCE: pressure line of the sprayer is provided with a flow gage of variable pressure differential. The gage is a pressure transducer (diaphragm) secured between flanges of the inlet and outlet branch pipes. The first pressure sensor is mounted in the inlet pipe, and the second pressure sensor is mounted in the outlet branch pipe. The outlets of both pressure sensors are open to appropriate inlets of an analog signal commutator with the system main line. The information output is connected to the digitizer input. The digitizer outputs are connected to the system main line microcomputer. EFFECT: convenience in operation. 10 dwg
