Basic Flow Measurments
6.0 Contact Hours (water or wastewater)
Using Technology to Measure Open-Channel Flow
Can’t tell a weir from a flume? Unsure when to use Q=VA or the Manning Formula? Having trouble measuring flow accurately? Alloway’s six-hour course “Basic Flow Measurements” is a practical course for anyone who regularly measures flow or performs sampling. The course will provide an overview of the methods and equipment used to measure open-channel flow in water and wastewater treatment facilities. The course will include a special presentation by Mike Minteer of Advance Instruments.
Who Should Attend
Operators, analysts, managers, and superintendents who work in water and wastewater treatment plants.
Course Description
Flow rate is a necessary detail for operating a treatment plant or regulating a channel, but measuring flow is not always straightforward. There are many variables to take into consideration: channel type, objectives, weather, and equipment available. This course will distinguish between open-channel and closed-channel flow measurements, paying particular attention to open channels. The course will cover the different methods of measuring open-channel flow, including area velocity (Q=VA), hydraulic structure methods, and the Manning Formula. The course will detail the uses and relative advantages and disadvantages of measuring devices. The course format will be a combination of lectures, problem sets, hands-on demonstrations, and field excursions.
Learning Objectives
This course will begin with the basics and progress to more advanced flow topics. At the conclusion of the course, participants should be able to:
- Identify the history and importance of measuring flow.
- Differentiate between open-channel and closed-channel flow systems.
- Describe the methods of measuring open-channel flow, including area velocity (Q=VA), dilution, hydraulic structures, the Manning Formula, and timed gravimetric methods.
- Discuss the uses of primary measuring devices, specifically flumes and weirs.
- List secondary measuring devices and understand when they are needed.
- Select the appropriate flow-measuring device for the task at hand.
- Calculate flow using the Manning Formula and the Q=VA discharge formula.
- Explain flow-proportional sampling.
