Articles about Coriolis flowmeters

Flow Research is working on a new study on the worldwide Coriolis flowmeter market, one of the fastest growing flowmeter markets, and this groundbreaking new study reveals the size of the 2024 worldwide Coriolis flowmeter market, including the market shares of all major suppliers and forecasts for the market through 2029.

The World Market for Coriolis Flowmeters, 8th Edition builds on studies Flow Research published in 2001,  2003, 2008, 2013, 2016, 2020, and 2023. We are determining:
• Worldwide supplier market size and shares for Coriolis flowmeters in 2024
• Market growth forecast through 2029
• Industries and applications where Coriolis flowmeters are used, including market growth sectors
• Strategies for manufacturers for selling into the Coriolis flowmeter market
• Company profiles and product analysis for the main Coriolis suppliers 
• Product descriptions and average selling prices in the market

The popular Coriolis flowmeter requires little maintenance and is highly accurate --  many Coriolis flowmeters achieve 0.1% or even 0.05% accuracy. In addition, Coriolis flowmeters can measure mass flow, which is useful for products sold by weight rather than by volume and for chemical reactions that are based on mass rather than volume. Process plants are increasingly selecting Coriolis meters to replace differential pressure (DP) devices.  Mass flow is especially appropriate for measuring gases, which are more readily affected by temperature and pressure than are liquids, and their use is growing in the oil & gas industry.  

Companies that need flowmeters for custody transfer, or want highly accurate measurement of mass, have a good reason to select Coriolis flow meters.  They find that despite a relatively high price tag, Coriolis flowmeters can provide a good return on investment.  

How they work

The roots of today’s Coriolis flowmeters can be traced back to the 1950s. This study includes a review of the early patents filed in the 1950s, 1960s, and 1970s.  it was not until 1977 that Micro Motion was founded and soon afterwards introduced the first  Coriolis flowmeter for laboratory applications. Since that time, a number of other suppliers have entered the market, including Endress+Hauser, KROHNE, Yokogawa, Rheonik, and ABB and have introduced a wide variety of models and types of Coriolis flowmeters.

Coriolis flowmeters contain one or more oscillating tubes. These tubes are usually bent, although straight-tube meters are also available now. The fluid to be measured passes through the oscillating tubes. The momentum of the fluid deflects the oscillating tubes. Pickoff coils passing through a magnetic field generate a sine wave on the inlet side and the outlet side. The phase shift or time difference between the defection in the tubes on the inlet and outlet sides is directly proportional to mass flow.

Why the Coriolis market is growing fast

A number of factors are contributing to the growth in the Coriolis flowmeter market:  

Custody Transfer. Custody transfer of natural gas is a fast-growing market, especially with the increased popularity of natural gas as an energy source, and Coriolis flowmeters are feeling the effects. Natural gas changes hands, or ownership, at a number of transfer points between the producer and the end-user. These custody transfer points are tightly regulated by standards groups such as the American Gas Association (AGA), which approved a report on the use of Coriolis flowmeters for custody transfer of natural gas in 2003. This report, AGA-11, has provided a significant boost to the use of Coriolis flowmeters for natural gas flow measurement. The majority of Coriolis suppliers now have meters that can measure gas flow.

In addition, suppliers have made a number of improvements in Coriolis technology, and Coriolis meters are now much better able to measure gases.  

Technological improvements

Suppliers continue to make technological improvements in Coriolis flowmeters. Straight tube meters have become more accurate and reliable, thereby addressing some of the drawbacks of bent tube meters, including pressure drop, the inability to measure high-speed fluids, and the tendency of bent tubes to cause fluid build-up. 

While bent tube meters still have advantages over many conventional meters, they do introduce pressure drop into the system. Pressure drop is an issue because in many cases the fluid has to be speeded up back to its original velocity. This costs money, as it requires the use of pumps. Another issue has to do with the tendency for build-up to occur around pipe curvatures. This can be a special problem for sanitary applications. Having a bent pipe also slows down the fluid, making it more difficult to meter high-velocity fluids.

Other improvements include the use of titanium and other construction materials that make the meters stronger and longer lasting, as well as a trend toward flowmeters that can effectively handle larger line sizes. More than any other meter, Coriolis meters have line-size limitations. Due to the nature of the technology, Coriolis meters get large and unwieldy once they reach the six-inch size. Even two-inch, three-inch, and four-inch meters are quite large. Rheonik has combined two six-inch Coriolis meters to create a meter that can handle larger line sizes. While it has sold a very limited number of these meters, it does represent an interesting and creative way to deal with the line-size issue. Other companies that have introduced Coriolis flowmeters for line sizes above six inches include Endress+Hauser, KROHNE, Micro Motion, and Shanghai Yinuo.

Low maintenance. Even though Coriolis meters have a higher purchase price than many other flowmeters, they may cost less over the lifetime of the meter due to reduced maintenance costs. Unlike turbine and positive displacement meters, Coriolis meters do not have any moving parts, apart from the vibrating tube. They are not subject to wear in the way that orifice plates are. With many companies reducing their engineering and maintenance staffs, having a meter that does not require a great deal of maintenance can be a major advantage.

Lower cost meters. Micro Motion, Endress+Hauser, and other companies have broken the price barrier, by offering lower-cost Coriolis meters in the $4,000 range rather than the more typical $9,000 to $12,000 range and up (depending on size). The lower price also means lower accuracy -- published accuracies are in the 0.5% range -- but these meters give end-users the option to buy into the advantages of Coriolis technology at a more affordable pricepoint..
