The World Market
for Flowmeters, 6th
completed our first Volume X study in 2003, and published subsequent editions in
and 2015. We have closely followed the growth in the markets
of all the flowmeter types during this time. The main goal of this study is to
determine the size of the
worldwide flowmeter market, including all technologies, and to see if the trend
towards new technology flowmeters continues. This study contains revenue, unit,
and average selling price data for all flow technologies, segmented by region.
It provides the tools you need to compare market size, market shares, and growth
rates for all the flow technologies. It also provides product analysis and
growth factors for each flowmeter type. Volume X enables you to assess your
competitive position in the flowmeters you supply and the ones you compete
against. Market forecasts through 2020 are included.
The study includes
both new-technology and traditional technology flowmeters, as well as the
emerging flow technologies of sonar and optical. This full-color study includes:
size of the worldwide market
for all of the major flowmeter technologies
• Market size forecasts for
each flowmeter type through 2020
shares for each flowmeter
type in 2015 with annual forecasts through 2020
• Both worldwide and regional market
size and market share data
• A technology
description and analysis for
each flowmeter type, including major competitive strengths and weaknesses
• A product
line analysis for the major
manufacturers of each technology type
profiles with product
information for easy comparison

About Variable Area
Most variable area
(VA) flowmeters consist of a tapered tube that contains a float.
The upward force of the fluid is counterbalanced by the force of gravity.
The point at which the float stays constant indicates the volumetric
flowrate, which can be often read on a scale on the meter tube.
VA meter tubes are made of metal, glass, and plastic.
Metal tubes are the most expensive type, while the plastic tubes are
lower in cost. Metal tubes are used
for high-pressure applications.

While most VA
meters can be read manually, some also contain transmitters that generate an
output signal that can be sent to a controller or recorder.
While VA meters should not be selected when high accuracy is a
requirement, they do very well when a visual indication of flow is sufficient.
They are very effective at measuring low flowrates, and can also serve as
flow/no-flow indicators. VA meters
do not require electric power, and can safely be used in flammable environments.
development for variable area
flowmeters is the development of meters with a transmitter output.
The HART protocol is available on some meters.
This turns the VA meter into more than a visual indicator, and makes it
possible to do control and recording. A
class of VA meters called purgemeters have been developed to handle a variety of
low flow applications. Other areas
of research include float design and materials of tube construction, especially
