Flowmeter
The Valeport ‘Braystoke’ Model 001 flowmeter is an easy to use and reliable method of measuring water velocity in a variety of open channel environments, making it ideal for field study use and hydrometric work.
The portable flowmeter and display unit are particularly useful for:
- education and outreach activities
- research and monitoring projects
- flow gauging technique training
This short video explains how to assemble and use our flowmeter to measure the velocity (speed) of water in a stream or river. By taking several velocity measurements at different points and depths in a stream, it’s possible to calculate an average velocity, and from this the flow rate.
The flowmeter in this video is a Valeport Model X which was kindly gifted to JBA Trust by the Canal and River Trust. It’s an impeller device which means it works by counting the number of revolutions of the yellow impeller over a fixed time period.
Factsheet: More information about the the flowmeter is available in this factsheet.
If the flowmeter would be useful for your work with students, professional groups or communities, please contact us for more information.
