Abstract

medidor de fluxo baseado na pressão para um bocal de pulverização. a presente invenção refere-se a um bocal de pulverização para um pulverizador agrícola inclui uma primeira válvula ativamente controlada configurada para controlar o fluxo através do bocal de pulve-rização. um primeiro sensor de pressão é disposto a montante da válvula e um segundo sensor de pressão é disposto a jusante da válvula. a posição de um membro da válvula pode ser detectada e um tamanho de um orifício restritivo definido pela válvula pode ser determinado com base na posição detectada do membro da válvula. um controlador é configurado para determinar uma taxa de fluxo através da válvula com base na diferença entre uma primeira leitura de pressão do primeiro sensor de pressão e uma segunda leitura de pressão do segundo sensor de pressão.
