El siguiente trabajo estudia nuevamente un sistema automáticod e muestreo de aguas residuales en alcantarillas. En él también se definen las partes del muestreador.

An automatic sewage sampling system in a manhole is provided to rapidly and easily sample std. H2O having no sludge so as to precisely measure H2O quality.  An automatic sewage sampling system includes a compressor installed adjacent to a manhole to generate compressed air, a control panel for operating the compressor and a control room.  A sample exhaust pipe, an air feeding pipe, and an air feeding pipe are installed in the control room.  A bracket is installed at a middle portion of the manhole and an air diaphragm is mounted on the bracket.  A float screen is integrally connected to a flexible suction hole so that the float screen is moved up and down as a H2O level varies.
