ABSTRACT:
This guage is adapted to measure the depth of fluid flowing past a flume or weir in a generally horizontally disposed conduit. It comprises a transparent tube or stilling well which contains a float, and which is adjustably secured by a pair of clamps to an elongate supporting rod. The float can be clamped against movement in the well by a hose, which extends downwardly in the bore of the well, and which is sealed at its lower end. The hose is connected at its upper end to a manually-operable vacuum device which can be manipulated either to collapse or expand the hose. In use the hose is collapsed and the lower end of the supporting rod is inserted downwardly into a conduit to support the lower end of the well a predetermined distance above the bottom of the conduit, and in advance of the associated weir or flume. The flowing fluid causes the float to rise in the well to a height proportional to the depth of the flowing fluid, after which the vacuum device is operated to expand the hose causing it to engage and clamp the float against further movement in the well. Thereafter the support is removed from the conduit and the now-clamped float is read against a graduated scale which is inscribed on the transparent well, and which is calibrated to indicate numerically the depth of the fluid in the channel.
