Open Channel Weirs - Volume Flow Measurements - Engineering ToolBox

Weirs are structures consisting of an obstruction such as a dam or bulkhead placed across the open channel with a specially shaped opening or notch. The flow rate over a weir is a function of the head on the weir. Common weir constructions are the rectangular weir, the triangular or v-notch weir, and the broad … Prikaži več The flow rate measurement in a rectangular weir is based on the Bernoulli Equationprinciples and can be expressed as: cd must be determined by analysis and calibration tests. For standard weirs - cd- is well defined or … Prikaži več The triangular or V-notch, thin-plate weir is an accurate flow measuring device particularly suited for small flows. For a triangular or v-notch weir the flow rate can be expressed as: Prikaži več For measuring the flow rate it's obviously necessary to measure the flow levels, then use the equations above for calculating. It's common to measure the levels with: 1. ultrasonic level transmitters, or 2. pressure transmitters … Prikaži več SpletSutro weirs are not used very often, due to their inherently weak structure and tendency to clog with debris. A rare example of a Sutro weir appears in the following photograph, … fully managed it services
