FlowTime Clock ...
What flowtime is it?

Time displayed is Flowtime.
Flow Research Establishes Flow Recalibration Working Group (FRWG)
Flow Research has established a new working group called the Flow Recalibration Working Group (FRWG). The purpose of this group is to arrive at a group of criteria that end-users can employ to determine if their flowmeters need to be recalibrated.  This does not necessarily equate to a specific time interval.  Instead, the goal is to have some tests, programs, or criteria that can be run to determine when a flowmeter needs to be recalibrated.

Coriolis Force or Coriolis Effect?
One common example given to illustrate the Coriolis force is that of a ball propelled through the air a long distance in a straight line from the North Pole towards a target on the equator.  By the time the ball arrives at the equator, it will not land at its apparent target, because the earth will have rotated sufficiently underneath the moving ball so that it will land some distance away from the perceived target on the equator.  From the perspective of the person standing where the ball is “thrown,” the ball will appear to have curved.

Volume X Reveals Flowmeter Market Trends
In 2013, new-technology flowmeters accounted for 59 percent in the market.  This is quite a change from 2002, when traditional flowmeters edged out new-technology flowmeters slightly.  By 2007, new-technology flowmeters had the edge.

Magnetic Flowmeters Now the Largest Market in terms of Revenues
Flow Research has just completed a study of the worldwide flowmeter market. One of our findings is that magnetic flowmeters generate more revenues worldwide than any other type of flowmeter.

What is the difference between Coriolis and ultrasonic flowmeters? 
Our research shows that these are the two fastest growing flow technologies. But there are important differences between the two.

The difference between thermal dispersion and calorimetric flowmeters
I believe I now see a difference between the thermal dispersion and calorimetric flowmeters. 

Calorimetric and Thermal Musings
Is a calorimetric flowmeter a type of thermal flowmeter or is it a distinct technology?

The History of Thermal Flowmeters
The history of thermal flowmeters is fascinating. Thermal flowmeters were born on the West Coast of the United States —the result of independent development by first two, then three separate companies. One company was Fluid Components International (www.fluidcomponents.com), which began by developing thermal flow switches that were used in the oil patch. The switches detected the movement of oil in oil well pipes, but they didn’t evolve into actual flowmeters until 1981.

Important Ultrasonic Conferences Sponsored by CEESI
One of the most important events in the flowmeter world is the annual Colorado Engineering Experiment Station, Inc. (CEESI) Ultrasonic Meter Workshop (USM).   The first of these events was held in Clear Lake, Iowa in 2001 and drew 37 attendees.   In 2013, the conference took place in July in Denver, Colorado with more than 180 participants.  The purpose of the workshop is to bring together many of the leading decision makers and theorists in the ultrasonic flowmeter community with end-users to discuss key topics related to products and applications. 

The World Outlook on Oil
Flow Research has recently completed a six volume study of the world oil and oil flow measurement markets. Here are some of our conclusions.

Part 1: Emerging Trends of Thermal Flowmeters
In this guest post, I’ll be comparing the Coriolis and Thermal flowmeter markets, an interesting undertaking when you consider some of the facts. Both technologies were introduced about the same time, in the mid-1970s. But the worldwide Coriolis meter market has grown to exceed $1 billion, while the Thermal flowmeter market is valued at less than 15 percent of that. Why the difference?

Part 2: Emerging Trends of Thermal Flowmeters
Last week in the first part of my guest post, I shared some of the reasons why the Coriolis flow meter has cornered such a large part of the flowmeter measurement market. Accuracy is the main reason why this type of flowmeter has been so commonly used in industrial applications up to this point. But this week I’ll provide some interesting facts that might just change your mind about the effectiveness of thermal flowmeters.
