Abstract

"DETECTOR DE PRODUTO VAZIO". O mecanismo de alarme da invenção sinaliza a ausência de um líquido de uma fonte de líquido aquoso. O mecanismo de alarme compreende um corpo de alarme tendo um orifício de saída; o orifício de saída; o orifício de entrada em comunicação de líquido com uma fonte de líquido, o orifício de saída em comunicação de líquido com um local de uso. O mecanismo de alarme adicionalmente compreende uma câmara de flutuador colocada em comunicação de líquido paralela com o orifício de entrada e o orifício de saída. A câmara do flutuador contendo um flutuador conectado de forma operável em um alarme. O flutuador, quando uma câmara é cheia com fluido, inabilita o interruptor de gerar um sinal. O flutuador, a medida que a câmara é esvaziada do líquido, alcança uma posição e é detectado energizando o interruptor para enviar um sinal de "pouco ou produto vazio". O aparelho opera passando o líquido através do corpo. A medida que o líquido na fonte de líquido é esgotado e não está mais disponível para passagem através do corpo, o corpo torna-se vazio de líquido a medida que a fonte de pressão remove o líquido do corpo e particularmente da câmara, fazendo com que o flutuador alcance uma posição gerando um sinal.
