Quem estiver passando por aqui, por favor, dê-me uma dica. Obrigado! Isso indica aquecimento de instrumentos? O quadrado com linha ondulada na frente do PG0402 indica um tanque de isolamento?

Amortecedor de pulso, usado para estabilizar o fluxo de saída da bomba; pelo diagrama PID, parece ser do tipo membrana.

O quadrado com ondas indica que a membrana impede o vazamento de substâncias perigosas em caso de danos no recipiente.
