Simple and Accurate Flow Measuring Devices in Agriculture Industry

Efficient water management in a developing country like India is of paramount importance. One critical aspect of this endeavour is the accurate measurement of flow in open channels, a task that comes with its share of challenges. Commonly used methods such as weirs and measuring flumes have their limitations, including issues like head loss, complexity, and sensitivity to changes in bed levels. Moreover, they often rely on intricate flow equations, making them less than ideal for practical water management. This study introduces a novel approach to flow measurement in open rectangular channels. Challenging conventional wisdom, it demonstrates the possibility of achieving a nearly linear depth-discharge relationship, even in a rectangular channel. The research introduces a novel optimization technique to determine flow parameters, offering a near-linear equation that holds true within a specific range of flow depths with minimal deviation, typically within ±2% error. In case of earlier flow measuring devices the devices were intrusive weather it is weirs or flumes, a modification in the structure was required whereas in the proposed flow measuring device no change is required.
