Executive Editor: Dr. Jesse Yoder; Volume 16, Number 2 - ISSN 1350-7204

1. Letter from the President

These are very exciting times at Flow Research.  We are working on the 3rd Edition of our gas flow studies.  We are also working on a new multiphase flowmeter study.  And we are researching two new flow calibrations studies: one for gas and one for liquid.

I am very pleased that the US Patent Office has approved my application for a new flowmeter design (see #2).  And ISA has published the new book I wrote with Dick Morley called The Tao of Measurement.

Please read the rest of FlowTimes for more information on these and other topics.  And be sure to contact us if you need any market research, or just to say Hello!   Thank you very much for your support over the years.

2. US Patent Office Approves Yoder Dual Tube Meter

Wakefield, Massachusetts; May 15, 2015 — Flow Research is pleased to announce that the United States Patent Office has approved the application by founder Jesse Yoder of a new dual tube flowmeter.  This flowmeter is designed to provide superior and more accurate measurement of flows in large pipes at a reduced cost.  The approved patent application applies to seven different flow technologies, including Coriolis, magnetic, ultrasonic, vortex, thermal, differential pressure, and turbine.

The new Yoder dual tube meter contains two equally sized round tubes placed within a meter body.  A sensor within each tube computes the flow within the tube.  The total flow through the pipe is then computed from the results of the flow measurement within the two tubes, plus a calculation based on testing.  The design works especially well in large pipes.  The Yoder dual tube meter uses smaller, less expensive dual sensors to measure flow more economically than larger sensors that have to cover the entire pipe.   It is also potentially more accurate because, unlike insertion flowmeters that measure flow at a single point, it makes two flow measurements and computes flowrate for each measurement.

According to Dr. Jesse Yoder, the inventor of the “flowtube” meter:

“The flowtube meter represents a major breakthrough in flow measurement technology for measuring flow through large pipes.  Not only does it promise higher accuracy and lower cost, it also opens up the possibility of mixing different flow technologies within a single meter.  This is not a completely new concept, but it is one that has not been adequately explored or implemented by flowmeter suppliers. It is easy to assume the idea that each flowmeter has to use only one sensor type (e.g., Coriolis, ultrasonic, etc.), while much can potentially be gained from using multiple technologies within a single meter.  This is the path already taken by inventors of multiphase meters.  Measuring flow through a pipe by measuring the flow through dual tubes inserted into the pipe is itself a revolutionary idea, and has the potential to change the flowmeter landscape across many flow technologies.”

The geometry underlying the flowtube meter is explained in Chapter Seven of Yoder’s new book, The Tao of Measurement, which was published in March 2015 by the International Society of Automation (ISA).  This chapter describes traditional Euclidean geometry, and proposes the round inch as a substitute for the square inch as a fundamental unit of geometric measurement.  The design of the flowtube meter follows logically from the use of the round inch as a unit of measurement for circular area.  However, the utility of the flowtube meter does not depend on circular geometry, and the geometry of the flowtube meter is completely consistent with traditional Euclidean geometry.

4. Rheonik No Longer Part of GE Measurement and Control

Wakefield, Massachusetts; April 8, 2015 — Rheonik, a supplier of large size Coriolis flowmeters, has undergone a management buyout and is no longer part of GE Measurement and Control.


GE acquired Rheonik in 2008.  Since that time, GE has marketed the Rheonik line of Coriolis meters, divided between RHE flow transmitters and RHM flow sensors that feature the Omega flow tube design with an increased signal to noise ratio.  This line included Coriolis flowmeters for inline pipe installations ranging from ¼ inch (threaded connection) up to 12 inches (flanged end) in diameter.  Rheonik models are approved for use in custody transfer applications, and can measure flowrates from as low as 0.07 lb/hour up to a high of 3,300,000 lb/hour.  The entire line is engineered for use in hazardous conditions as it has both ATEX and CSA approvals.

In 1984, Karl Küppers began the design of a new Coriolis flowmeter that later became the patented Omega tube Coriolis Mass Flowmeter that is marketed by Rheonik today.  This meter was granted a patent based on its unique operational and construction features.  Karl Küppers founded Rheonik Messgeräte in 1986.  It was initially located near Munich , Germany , but as it grew, the company relocated to Odelzhausen , Germany , where it is currently located.

Management Buyout

On October 10, 2014 GE divested itself of Rheonik through a management buyout of Rheonik.  This former division of GE Measurement and Control became Rheonik Messtechnik GmbH, and assumed the assets of the former Rheonik division of GE.  Rheonik Messtechnik is continuing to offer the same lines of RHE flow transmitters and RHM flow sensors with the Omega flow tube design.  This makes it one of four companies in the world that offer large line size Coriolis flowmeters; the other three are Emerson Process Management (Micro Motion), KROHNE, and Endress+Hauser.  Large line size Coriolis meters are those for line sizes above six inches.

Coriolis meters are prized for their high accuracy and reliability.  They play a major role in the downstream market for measuring petroleum liquids, where they mainly compete with positive displacement meters.  While they perform best on liquids, recent technology improvements are making them more competitive in the gas measurement market.

5. FMC Technologies and Technip to launch Forsys Subsea : Revolutionizing subsea field architecture from concept to delivery and beyond

Houston, TX; March 22, 2015 — FMC Technologies, Inc. and Technip today signed an agreement to form an exclusive alliance and to launch Forsys Subsea, a 50/50 joint venture that will unite the skills and capabilities of two subsea industry leaders. This alliance will redefine the way subsea fields are designed, delivered and maintained.

Bringing the industry's most talented subsea professionals together early in the project concept phase, Forsys Subsea will have the technical capabilities, products and systems to significantly reduce the cost of subsea field development and provide the technology to maximize well performance over the life of the field.

By combining the industry-leading technologies of the parent companies, Forsys Subsea will reduce the interfaces of the subsea umbilical, riser and flowline systems (SURF) and subsea production and processing systems (SPS). It will also simplify the seabed layout, reducing complexity, accelerating time to first oil, and maximizing sustainable peak production. This unique combination will drive a new, step-change approach to how equipment designs and installation methods converge in a new generation of subsea architecture.

Gathering the expertise and experience of its parent companies, Forsys Subsea will focus on:

·        Early involvement in the concept selection phase of front-end engineering and design, when ability to influence cost is greatest.

·        Integrated life-of-field well surveillance, monitoring, data interpretation and advisory services.

·        Joint R&D to drive technological innovations that will boost efficiency and further reduce development costs.

In addition, the alliance will be uniquely positioned to deliver and install a seamless subsea infrastructure from seabed to topside by eliminating interfaces and by integrating SPS with SURF, attaining the highest reliability and uptime and the lowest total ownership cost available in the industry.

6. The Growing Popularity of LNG and its Importance to the Flow Industry

By Jesse Yoder, PhD, Flow Research

The world’s demand for energy is continuing to expand. This is true based on population growth alone.  However, most countries in the industrialized world are continuing to build new plants and improve their standard of living. All of this takes more energy, and it has many people and companies around the world scrambling to find the energy to power their constantly upgraded economies.

Because coal, nuclear, and renewables all have their problems as sources of energy, much of the world has come to rely on oil and gas as their main energy sources. Since August 2014, the average price of a barrel of oil has dropped from the $90 to $100 range to about $50. This is due to increased supply and decreased demand in some countries. The practice of drilling for oil by fracking has significantly increased oil production in the United States and elsewhere. And China and some other developing countries have experienced slowdowns in their economies. At the same time, the Organization of Petroleum Exporting Countries (OPEC), led by Saudi Arabia , has chosen not to cut production to maintain high price levels.

It is not clear to what extent the drop in oil prices will impact natural gas consumption around the world. Natural gas has been viewed as a cleaner and often more economical form of energy than oil. And the motivation to develop renewable energy is reduced with lower oil prices. However, considering the history of oil price fluctuations, and the fact that the worldwide demand for oil is increasing at a rate of about one million barrels per day every year, it seems likely that the drop in oil prices is temporary. And while the price of oil may not return to the $100 per barrel range anytime soon, it seems more likely that the oil price trend over the next year will be up rather than down. 

LNG Presents Opportunities for Flow Measurement

While coal is plentiful in many Asian countries, where oil and gas is scarce, the environmental consequences of burning coal is turning many of these countries toward natural gas.  LNG is the most efficient way to transport natural gas to many of these countries. Some companies such as GE Measurement and McCrometer have developed flowmeters specifically for LNG. Others are selling into this market with cryogenic flowmeters. While much of the world’s natural gas is still delivered by pipeline, the use of LNG is growing in popularity, especially in the Asia-Pacific region. This presents an opportunity for flowmeter companies who are in a position to take advantage of it.
