Patent ID: 8806960

Claim:
A flow measurement device for measuring fluid flow in a fluid source, said flow measurement device comprising: a housing defining a cylindrical inlet and cylindrical outlet; a pipe for transmitting fluid situated within said housing, with said pipe having a segmented section of the pipe circumferentially detached from the pipe so that said segmented section has an inlet and an outlet and can move independently from the rest of the pipe with the pipe and segmented section in contact with each other longitudinally and both the pipe and the segmented section each having an inner surface and an outer surface; a liner, having an inner surface and an outer surface, inserted into the pipe and the segmented section so that the outer surface of the liner is in contact with the inner surface of the pipe and the segmented section so that the outer surface of the liner is in contact with the inner surface of the pipe and the inner surface of the segmented section of pipe; a flow indicating means located within the housing and connected to the outside surface of the segmented section of pipe therein enabling the flow ascertaining means to detect motion in the segmented section; an electronic signal recorder located within the housing and electrically connected to said flow ascertaining means and configured to record the output of the flow ascertaining means; and a signal converter electrically connected to the electronic signal recorder and configured to convert the output of the electronic signal recorder into a volumetric flow rate therein capturing the flow of fluid passing through the segmented section of the pipe.
