The rod is divided into the first and second portions. The first portion of the rod contains a channel wherein there is a rotating shaft of the fluid monitoring apparatus. The channel is linearly connected with the outlet when the rod is found in the closing positions of the fluid path, and is disconnected when the rod is fixed in the opening position of the fluid path.
