In the field of flow measurement, what is needed in general rule is to design devices that are
inexpensive, fairly accurate, and easy to implement. Some devices are more accurate than …

In this paper, the outflow process of a linear width contraction device for a free-flow condition
is modeled using the dimensional analysis and the incomplete self-similarity condition. The …

Different experiments and numerical simulation research were carried out in order to explore
the hydraulic characteristics and applicability of the cutthroat flume, NACA airfoil-shaped …

Flumes with a local contraction of the channel width are a common way for accurately
measuring the flow discharge. In this paper, the outflow process of rectangular broad and …

This work experimentally investigated a modified venturi flume formed by placing portable
cylinders vertically upright in trapezoidal channels, referred to herein as the cylindrical …

In this study, the flow through a simple low-cost flume constructed using two semi-cylinder
contractions on either side of a rectangular channel was experimentally investigated. In …

Achieving accurate flow measurement in small channels is important to improve water use
efficiency and reduce agricultural water waste. Commonly used fixed flumes have the …

An analytically derived discharge prediction model for a conical mobile flume, referred to as
a conical central baffle (CCB), is presented. The flume is suitable for use in small rectangular …

The article looked at the possibility of making use of a lateral contraction as a flow
measurement device in a rectangular open channel. The contraction under consideration …

In order to improve the fine optimization technology of flow measurement facilities in
irrigation areas, the hydraulic characteristics optimization system of an airfoil pillar-shaped …
