<p>MEASURING DEVICE FOR WATER FLOW IN A BURIED PIPE A measuring device to determine the depth of sediment in the floor of a buried pipe and the rate of flow of water through the pipe. The device includes a first shaft with a sleeve telescoped on the shaft with the lower end of the shaft being adapted to engage the floor of the pipe and with the lower end of the sleeve being adapted to rest on the surface of sediment in the pipe so that the relative axial displacement of the sleeve in relation to the pipe will measure the depth of sediment in the floor and float which is connected to the sleeve and includes a lift member for raising and lowering the float on a suspension means which is operably connected to a switch so that when tension on the suspension means is relaxed when the float is supported by the water instead of a suspension means, energy from a source flows through the switch and indicates the relaxation of the tension and o the float there is provided a member which is movable in reponse to the rate of water flow through the pipe and which is connected to an electrical circuit to indicate the rate of flow of water through the pipe.</p> |
