  • Sampling apparatus for fluid
    Patent number: 3962922
    Abstract: Fluid flowing in an open channel or aqueduct having a notched dam or weir produces a hydraulic head at the weir which is proportional to the rate of flow of the fluid in the aqueduct. A sampling device is provided in association with the aqueduct just upstream from the weir which is adapted to scoop up a sample of the flowing fluid in a quantity which is proportional to the hydraulic head. That quantity of fluid may then be measured as a function of the flow rate.
