Flow Research has invented a new type of flowmeter with the potential to have a major impact on the flowmeter world. This device, first announced in August 2013, creates a new method of measurement that uses an internal measuring methodology to reduce space, weight, and cost by confining the measuring to the interior of the pipe — without the use of external meters.

We believe this dualtube flowmeter can increase the efficiency and accuracy of existing flowmeters, enhancing the performance of an existing meter and providing increased accuracy and reliability at reduced cost. Moreover it may be used to measure flow in large diameter pipes without heavy external flowmeters.
The dualtube method of measurement will work with Coriolis, ultrasonic, magnetic, thermal, vortex, differential pressure, turbine, and other types of flowmeters. The meter works with an existing inline flowmeter by making a measurement in a reduced area of the pipe. Advantages of this method include enhanced accuracy, reduced pressure drop, less sensitivity to flow profile, and reduced cost.
Jesse Yoder’s first received a patent for the meter in July 14, 2025 (US 9,080,908) and a second broader patent in August 8, 2017 (US 9,726,530).
CEESI successfully tested prototypes of a vortex dualtube meter built by Vortek Instruments and a turbine dualtube meter built by Hoffer Flow Controls.
Background
Flow Research has been researching and analyzing the flowmeter and instrumentation markets since 1998. During this time we have visited over 100 flowmeter and end-user companies in many parts of the world. We have seen many flowlabs, and talked to hundreds of people about the advantages and disadvantages of different flowmeter types. We have also published more than 150 market studies that include analyses of every type of flowmeter. This includes market size, market shares, company profiles, and product analyses. Dr. Yoder, company founder, has also authored more than 300 published articles on instrumentation topics in industry journals. During this time, we have come to appreciate the need for more accuracy and reliability in the available flowmeters.
We believe that this newly invented flowmeter will fill a critical need in the flowmeter community. On the one hand, it will not require end-users to become familiar with and invest in completely new technology. On the other hand, it will enable suppliers to manufacture flowmeters with enhanced accuracy and reliability at reduced cost. While this may not be the “perfect” flowmeter, it is a step in the direction of a better flowmeter.
Seeking partners
Flow Research is seeking partners interested in licensing this technology. We believe that it has the potential to transform the flowmeter market.
