Abstract:
An apparatus for monitoring and regulating the flow of liquid in a pipe comprising:a support fixedly connected to the pipe; a control shaft rotatably engaged to said pipe and said support; a valve fixedly engaged to said control shaft; a first impeller fixedly engaged to a first impeller shaft rotatably connected through the pipe to a first meter; a second impeller fixedly engaged to a second impeller shaft rotatably connected through the pipe to a second meter; a bar slidingly engaged in said support; a cable fixedly connected to said bar; a timer mechanism fixedly connected to said cable and to a timing gear; a main gear engaged with said timing gear and fixedly connected to a main gear shaft and a main gear engagement disk; a first impeller shaft disk fixedly connected to said first impeller shaft and engaged with said main gear engagement disk; a second impeller shaft disk fixedly connected to said second impeller shaft and engaged with said main gear engagement disk; and wherein rotation of the first impeller shaft and the second impeller shaft causes the main gear to rotate and create tension in the cable thereby actuating the bar and closing the valve so that the flow of fluid within the pipe is stopped.
