Duonyms
Read more: DuonymsA duonym is a word made up of two words that are put together to make a word with a new meaning. For example, in the word “butterfly” the words “butter” and “fly” are put together to form a word with a new meaning. Other examples are “baseball” and “egghead.” The word “duonym” is formed…

Patently important
Read more: Patently importantWhy are patents important? Today, much of the discussion around flowmeters focuses on present innovations and future developments. Examples include communication protocols, the Internet of Things (IoT), the limits of accuracy and repeatability, lighter and more durable materials of construction, and artificial intelligence. These examples are all important, and they influence the direction of flowmeter…

Why some meters are more accurate than others
Read more: Why some meters are more accurate than othersWhy are some flowmeters more accurate than others? There are many types — e.g., Coriolis, ultrasonic, vortex, magnetic, DP, turbine, and variable area (VA). Each measures flow in a different way and with its own accuracy. But the deeper question is why some flowmeters are more accurate than others. I believe the single most important…

Is Our Universe Rotating due to the Coriolis Effect?
Read more: Is Our Universe Rotating due to the Coriolis Effect?Have you wondered what the rotating graphic is in this post? This is a graphical representation of a proton in the form of a hurricane. The idea is that a proton with its quarks, gluons, and other subatomic particles traveling at near-light speed resembles a hurricane in structure. The elements of a proton are held…

Why care about pi?
Read more: Why care about pi?Knowing the value of π is crucial to accurately measuring flow through a round pipe. The formula for determining the volumetric flow through a pipe is Q = A * v. Here Q is volumetric flow, A is the cross-sectional area of the pipe, and v is the average velocity of the flow. We need…

Looking behind to look ahead
Read more: Looking behind to look aheadWhen you think about the flowmeter industry, it is natural to want to look ahead to see where the industry is going. If you look ahead, you might think about the future of smart instrumentation, self-diagnostics, lighter-weight materials, and artificial intelligence. Looking ahead is important and is part of strategic planning. On the other hand,…

Filling in the Blanks in the Vortex Story
Read more: Filling in the Blanks in the Vortex StoryI’ve learned a lot since I first set out to determine who introduced the first working commercial vortex flowmeter. I found out that it was Yokogawa in Japan, who introduced insertion vortex meters for flare stacks. The development of this meter was done in Japan, and was based on university and academic research. This was…

The Rope Experiment and the Area of a Circle
Read more: The Rope Experiment and the Area of a CircleCalculating a Rational Value for the Area of a Circle I would like to go back to “The Rope Experiment” to explain more completely how this gives us a rational value for the area of a circle. The Rope Experiment. Start with a rope shaped as a circle with a radius of 2. Now cut…

Calculating the Cross-Sectional Area of a Pipe
Read more: Calculating the Cross-Sectional Area of a PipeWith all the sources of uncertainty in flow measurement, the last thing we need is another source of uncertainty based on the geometry of flow. Yet there is such a source of uncertainty that has to do with calculating the cross-sectional area of a pipe.
