1. Letter from the President

Ultrasonic, Coriolis, and multiphase flowmeters grab Intellectual mindshare











An elk at the top of the Rockies.

Take a step forward with us!

During the third week of June, I was fortunate enough to spend nine days in Colorado at the foot of the Rocky Mountains .  The main reason for my visit was to attend the Ultrasonic Meter Workshop (USM) and the International Symposium on Fluid Flow Measurement (ISFFM), held in Colorado Springs .  Both conferences, which were held from June 17 – 22, were sponsored by Colorado Engineering Experiment Station, Inc. (CEESI).  The first USM was held in 1999 with 30 attendees, and this was the 14th annual conference.  This year the USM drew 213 participants.


The purpose of both conferences is for speakers to present the results of ongoing research.  There were also exhibits, including an exhibit by Flow Research, but the emphasis of the conferences is more on intellectual exchange than on product announcements.  Topics included ultrasonic recalibration intervals, installation effects, flow conditioning, and self-monitoring devices.  There was ample chance for networking at both conferences, and many of the leaders in the field of ultrasonic flowmeters attended.


One topic that came up but was not resolved is the difference between the terms ‘path’ and ‘chord’ as applied to multipath ultrasonic meters.  I discussed this with representatives from both Cameron and KROHNE.  According to my best understanding, a “chord” is an ultrasonic signal that travels from one side of a pipe to the other.  A “path” is an ultrasonic signal

that typically travels from one side of the pipe to the other and back.  So in many cases an ultrasonic flowmeter has more chords than paths.  This discussion is important because many people associate a larger number of paths with higher accuracy, but the terms ‘chord’ and ‘path’ sometimes are used as if they mean the same thing.  For example, Elster’s Q.Sonic Plus ultrasonic meter has six paths and 16 measurement chords.  

Ultrasonic is one of the few flow technologies that has spawned its own conference or workshop.  In addition to CEESI’s USM, the North Sea Flow Workshop is held every year, alternating between Norway and Scotland .  I attended the North Sea Flow Workshop in October 2011, held in Tønsberg , Norway .  The focus of this conference is on ultrasonic, multiphase, and Coriolis flowmeters.  This conference presents another opportunity for researchers to present their findings, and to discuss cutting edge topics related to these flowmeter types.  Both the CEESI conference and the North Sea Flow Workshop provide excellent opportunities to see the latest products and to discuss key topics in flow.  

Flowmeter conferences provide more than the ability to present papers and view exhibits.  A lot of interaction among the participants goes on at these conferences, and technical problems are discussed by suppliers and end-users alike.  This facilitates research and promotes the development of new features and products.  This type of interaction is not typically going on among positive displacement, turbine, and variable area flowmeter suppliers and users.  The growing interest in and attendance at ultrasonic, Coriolis, and multiphase conferences helps demonstrate that these technologies are at the cutting edge of flow.  Today, ultrasonic, multiphase, and Coriolis flowmeters have grabbed much of the intellectual mindshare of the flowmeter world.

2. Flow Research conducts three-pronged multi-study analysis of the ultrasonic flowmeter market

Flow Research is conducting a 3-study analysis of the worldwide ultrasonic flowmeter market.  This is our 4th edition of this study.   The three component studies are as follows:

Core Study: The World Market for Inline Ultrasonic Flowmeters

Module A: The World Market for Clamp-on and Insertion Ultrasonic Flowmeters

Module B: Worldwide Ultrasonic Flowmeter Market View

Module A is already shipping and covers both clamp-on and insertion ultrasonic flowmeters.  This module gives detailed market sizes, analysis, and forecasts for clamp-on and insertion ultrasonic flowmeters worldwide, including break-outs for eight geographic regions.  It gives market size for 2011, and forecasts the market through 2016, in both US dollars and in units.

This study accomplishes the following objectives:

·        Determine worldwide supplier market size for clamp-on and insertion ultrasonic flowmeters

·        Determine worldwide market shares for the clamp-on and insertion ultrasonic flowmeter market in 2011

·        Forecast market growth through 2016

·        Identify the industries and applications where clamp-on and insertion ultrasonic flowmeters are used, and to identify market growth sectors

·        Provide strategies to manufacturers for selling to the clamp-on and insertion ultrasonic flowmeter market

3. The World Market for Mass Flow Controllers, 2nd Edition is now shipping!

Our first edition of this study was published in 2008.  We published this new edition in response to requests from a number of companies for an update.  We had very good participation in the study, and are very excited about the research, which we designed for an expanded look at the mass flow controller market.

Our first edition included the semiconductor, industrial, and lab/research markets.  In addition to the original segmentation, we have added some new segmentation in this 2nd Edition.  For example, we have expanded the geographic regions, added distinctions for liquids and gas, and added segments related to flowrates.

One reason for doing an update of this study is that some companies that mainly supply to the semiconductor industry are looking to expand into the industrial segment, or to expand their offerings in this segment.  Therefore, we took a more in-depth look at MFC applications in other industrial segments, such as fuel cells, biotech, and solar/photovoltaic, as well as taking a new look at the lab/research markets.  Some of these markets are growing rapidly, and offer significant opportunities for mass flow controller suppliers.  This edition segments the Semiconductor, Industrial, Lab/Research industries by eight geographic regions, providing both revenues and unit sales for each.

This study includes both thermal and non-thermal mass flow controllers.  Non-thermal mass flow controllers are typically DP-flow based, with a laminar flow element.  It distinguishes between those mass flowmeters that are shipped as controllers, and those that are shipped as flowmeters without control.  It gives detailed market sizes, analysis, and forecasts for the mass flow controller market worldwide, with market size for 2011, and forecasts the market through 2016.

The study accomplishes several important objectives:

·        Determine the 2011 market size in US dollars and unit volumes for mass flow controllers worldwide, both thermal and non-thermal types

·        Determine the 2011 market shares of leading suppliers of mass flow controllers worldwide

·        Forecast market growth for all types of mass flow controllers through 2016

·        Identify industries and applications where mass flow controllers are used, and identify growth areas

·        Provide company profiles of the main suppliers of mass flow controllers

·        Provide a product analysis for the main companies selling into the mass flow controller market

·        Provide strategies to manufacturers for selling into the mass flow controller market

4. KROHNE launches the OPTIMASS 6400: new twin bent tube Coriolis mass flowmeter for liquid and gas applications

The following are excerpts from a KROHNE press release.


·        New twin bent tube Coriolis mass flowmeter for liquid and gas applications

·        Advanced Entrained Gas Management (EGM): no loss of measurement with gas entrainment up to 100%

·        For high temperatures +400°C / 752°F down to cryogenic applications -200°C / -328°F

·        New signal converter with advanced device and process diagnostics, compliant to NAMUR NE 107

·        Liquid and gas custody transfer approval

Duisburg , June 14, 2012:  At Achema 2012, KROHNE introduces the new OPTIMASS 6400. Enhancing KROHNE’s OPTIMASS portfolio of Coriolis mass flowmeters, the OPTIMASS 6400 is an all-new twin bent tube Coriolis mass flowmeter to meet standard liquid and gas applications in the chemical and petrochemical, oil & gas, pharmaceutical, food & beverage, energy & power industries.

The OPTIMASS 6400 is the world’s first Coriolis mass flowmeter to feature advanced Entrained Gas Management (EGM). In the past, gas entrainments in liquid media presented a huge challenge for mass flowmeters because the relative movement between gas and fluid dampens the amplitude of the measuring tube. This dampening leads to inconsistent sensor amplitudes, which interfere with the electronics’ capability to determine the actual resonant frequency. While other mass flowmeters simply "freeze" their last stable reading to cover this "loss of measurement", the OPTIMASS 6400 with EGM is able to follow and correct for the varying amplitudes. This is achieved for entrained gas up to 100% of volume and continues to present an actual measured reading, together with an indication or configurable alarm for the user.

The entire press release will also appear in our upcoming Market Barometer.

Market Barometer, part of our Worldflow Monitoring Service, is a quarterly publication that focuses on the flowmeter industry, reporting on important technology introductions, mergers and acquisitions, and application trends.  For more information, visit http://www.worldflow.com.


5. Some thoughts on Ultrasonic Flowmeters – terminology, uses, and calibration

This is an excerpt from the Ultrasonic Flowmeters section of an article, Gas and oil measurement still dominate the complex world energy picture, by Jesse Yoder, PhD, Flow Research, in our most recent Energy Monitor.

Multipath ultrasonic flowmeters rely on three or more ultrasonic pulses that cross a pipe and then bounce back to the other side.  This is typically done at an angle.  Each path is associated with a pair of transducers.  One transducer sends the pulse and the other transducer receives it.  Multipath meters are more accurate than single and dual path meters because they measure the flow at multiple locations.  Mutipath flowmeters typically have four, five, or six paths, although some have been developed with eight or more paths.

The terminology of multipath ultrasonic meters has become somewhat confusing because some suppliers have introduced the term ‘chord’ to describe their multipath meters.  The term ‘chord’ refers to an ultrasonic pulse that travels from one side of a pipe to the other.  In this sense, a chord is half a path.  The new Elster Q-Sonic Plus has 16 chords and six paths.  There is nothing wrong with the “chord” terminology, as long as it is understood that a chord does not equal a path.

Many companies are changing from DP and turbine meters to ultrasonic meters because of their marked advantages.  Ultrasonic meters are nonintrusive, cause virtually no pressure drop, do not have moving parts, are highly reliable, and are very accurate.  Leading suppliers of ultrasonic flowmeters for custody transfer of natural gas are Emerson Daniel, Elster, and SICK.  KROHNE has also entered this field.  These meters are widely used for pipeline measurement of natural gas.  Like turbine meters, they can accommodate the large sizes of gas pipelines, but they can more easily handle particles and impurities in the flowstream than turbine meters.  The market for custody transfer of natural gas has become the fastest growing niche in flowmeters, with the possible exception of the market for multiphase meters.

One issue that has remained unresolved is how often ultrasonic flowmeters need to be recalibrated.  Some companies look for a period of years, such as five years or seven years, as a guide.  So far none of the standards bodies, such as AGA, the American Petroleum Institute (API), or the International Organization for Standardization (ISO) have adopted such a standard.  While the number of years would be a convenient guide, there are also diagnostic tests that can be run that may provide a better guide to the need for recalibration of an ultrasonic flowmeter than a standard that is stated in terms of a number of years.

The entire article can be found in the Issues and Perspectives section of our most recent Energy Monitor, Q1 2012.

Energy Monitor, part of our Worldflow Monitoring Service, is a quarterly publication that focuses on the oil & gas, refining & petrochemical, and power and renewable industries in relation to flow and temperature measurement, and other instrumentation.  Each issue surveys the energy scene to discover significant new events, trends, and opportunities.  For more information, visit http://www.worldflow.com.
