Abstract

Patente de Invenção: <B>"CONTROLE DE NìVEL DE LìQUIDO EM UM EMISSOR DE GOTìCULA ACúSTICO"<D>. Um emissor de gotícula acústico, o qual uma placa de controle de nível de líquido tem um lábio em contato íntimo com a superfície livre de um líquido, é construído. A placa de controle de nível de líquido também tem um diâmetro de abertura efetivo na borda de saída da placa o qual é maior do que o diâmetro de abertura efetivo no lábio. Isto reduz a sensibilidade à pressão da superfície livre do líquido e permite que a superfície livre do líquido seja efetivamente pregada na superfície inferior da placa de controle de nível de líquido para variações mais amplas na pressão do que utilizando os métodos convencionais.
