Abstract
A unitary molded venturi flume unit, for use in measuring liquid flow through a conduit, has a closed-end well section at one end of the flume throat and a connecting nipple section defining an access passage which extends from the lower portion of the well for sealed connection with a conduit. The walls of the throat and well sections extend substantially above the access passage and cause all liquid flowing through the conduit to flow through the throat. In use, a tranquil flow pool of the liquid is formed at the inlet side of the throat section. The depth of this tranquil flow pool exceeds the depth of normal rapid flow in the conduit, and may substantially exceed the height of the access passage and connecting conduit, for accurate measuring of flow through the conduit over a wide range of flow rates by sensing of the amplified liquid head on the inlet side of said throat.
