A tool designed to determine the flow rate of liquids passing over a triangular-shaped obstruction in an open channel. This instrument provides estimations of volumetric discharge based on the height of the liquid above the vertex of the triangular notch. For instance, if a stream flows through a constructed channel incorporating this specific obstruction, the calculator, when supplied with the liquid level, will approximate the quantity of fluid exiting the channel per unit time.
Accurate liquid flow measurement is critical in various fields, including irrigation, wastewater treatment, and industrial process monitoring. Devices which perform this function provide a cost-effective and relatively simple method for assessing flow rates in open channels. Historically, these structures have been employed for centuries to manage and quantify water resources, leading to standardized equations and calculation methodologies implemented in the automated version.
