  • Flow measuring apparatus
    Patent number: 4571997
    Abstract: A flow measuring apparatus adapted to be installed temporarily in the end of a sewer pipe or water pipe or conduit is provided with a weir/orifice plate and a bubble tube for sensing the hydraulic pressure at a critical point below the weir/orifice plate to facilitate determination of the flow rate by a calibrated relationship with the measured pressure. A cylindrical support frame is provided for placement in the pipe outlet, together with an inflatable collar which, when inflated, provides a seal between the inside diameter of the outlet pipe and the support frame. A base weir/orifice plate is fixed across the upstream face of the support frame and means are provided for fastening interchangeable weir/orifice plates to the base weir/orifice plate. An extension handle is provided so that the operator can install the measuring device in an exposed pipe or conduit located in a vault or manhole without entering the vault or manhole.
