Flow Measuring Equation of Ultrasonic Open Channel Flowmeter:
- The flow is often calculated based on the equation: Flow Rate = Velocity × Area. For standard flumes or weirs, specific empirical formulas are used to determine the flow rate from the water level.
Common Channel Configurations:
- Flumes: Devices such as Parshall flumes are commonly used to standardize open channel flow measurements. They control the flow and create a known relationship between water depth and flow rate.
- Weirs: Weirs are structures over which water flows, and the height of the water above the weir provides a direct measurement of the flow rate.Technical data of Ultrasonic Open Channel Flowmeter:
