US Patent Office Approves Yoder Dual Tube Meter
Wakefield, Massachusetts; May 14, 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
Flow Research Invents New
Type of Flowmeter
Flow Research has invented a new type of flowmeter
that has the potential to have a major impact on the flowmeter world.
This device creates a new method of measurement without the use of
external meters that uses an internal measuring methodology to reduce
space, weight, and cost by confining the measuring to the interior of the
pipe. Flow Research’s
flowmeter will increase the efficiency and accuracy of existing flowmeters.
This new method of measurement will work at least with Coriolis,
ultrasonic, magnetic, thermal, vortex, differential pressure, and turbine
The new flowmeter [patent pending] 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. This
new type of meter will enhance the performance of an existing meter and
provide increased accuracy and reliability at reduced cost.
Moreover it may be used to measure flow in large diameter pipes
without external heavy flowmeters.
this New Flowmeter
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
Jesse Yoder, company founder, has also authored more than 200
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.
Flow Research is seeking partners who are interested
in licensing this technology. We
believe that it has the potential to transform the flowmeter market.
