Gimme that old time flow
Size guide, vortex video
This website, “Vortex flowmeters,” has multiple content sources, including a selecting and sizing guide, a video on the vortex flow measuring principle, and articles on flow measuring for liquids, gases and stream, and a steam generation and distributions handbook.
Video and shedding history
This online article, “What is a vortex flowmeter?,” starts with a short video on how they work, and traces vortex-shedding history and Theodor von Kamen’s principles, as well as flowmeter design, style, accuracy and rangeability, and installation recommendations.
Curves for float shapes
This five-minute video, “Flow measurement (rotameters),” is part of a process-engineering lecture series by Kevin Harding at the University of Witwatersrand, Johannesburg, South Africa. It addresses float issues, orifice plate equations, and performance results for different float shapes.

Calibrating rotameters
Because rotameters or variable area flowmeters employs floats and other mechanical components, they need routine calibration to maintain accuracy. This online article, “Rotameter calibration,” shows how to do it, what equipment is needed, how to connect/adapt flow paths, several scenarios, and a video about specific solutions.
Bubblers, weirs, flumes
This hour-long video, “Open-channel flow measurement” by Darrell Kuta, flowmeter business development manager at Teledyne ISCO, covers sensor types, ultrasonics, radar level, bubblers, submerged pressure probes, flow calculations, primary devices, weir and flumes, In addition, it covers the sensors that serve them, such as velocity and non-contact radar sensors.

Changing open channels
This online article, “Measuring open channel flows” by Andrew Helbling, product specialist at Tracom, covers the Manning formula, time gravimetric, area-velocity, dilution and other issues.
Turbine basics and rates
This online article, ‘What is a turbine flowmeter?,” answers some basic questions, and covers high-flow-rate models for wastewater, advantages and limits, application recommendations, comparison with other methods, and installation and accessories.
Compare to paddle wheel
This multi-part blog post, “The ultimate guide to turbine flowmeters: operation, design and applications,” covers functions, construction, common applications and sensors, and a comparison with paddle-wheel flowmeters.
Magnetics explained
This online article, “Magnetic flowmeter explained/working principles,” covers Faraday’s law, signal transmission, conductive fluids and installation considerations. It even comes with a complementary 10-minute video on the same principles.
Pros, cons, comparisons
This webpage, “Understanding magnetic flowmeters,” covers functions, advantages, accuracy, straight-pipe requirements, turndown ratios, sizing, limitations and applications, as well as comparisons with Coriolis, mass flow and ultrasonics flowmeters.
