In today’s fast-paced flow meter market, user demand for higher accuracy and reliability is causing a shift towards new technology flow meters, especially ultrasonic and coriolis. It is marked that new technologies are replacing traditional meter types. As a result we can see ultrasonic, vortex, magnetic, coriolis and thermal flow meters are supplanting differential- pressure, turbine systems and positive displacement in many applications. This development is going on from minimum ten years.
These new technology flow meters are less invasive, more precise and more consistent than Nearly all traditional- technology meters. There was a time when few companies were facing lessening of engineering staff and end-users were more and more looking for “place it and forget it” tendencies in flow measurement systems. New technology meters such as coriolis and ultrasonic are practically costly in comparison of traditional meter. End-users found that this meter gives higher performance and it also reduces the maintenance cost. These users also realized that it is more important to look at total cost of ownership rather than just purchase price. This thought gave breathing space to new technology flow meters and now they are used in more and more applications.Market of ultrasonic and coriolis flow meter are two of the fastest growing flow meter sectors. In particular ultrasonic flow meter’s market has shown an express development in last five years. According to the study by Flow Research, in 2002, worldwide size of ultrasonic flow meter market was $ 255 million. By 2007 market became greater than ever the growth was of from $ 255 million to $ 440 million. The statistics assembled by Flow Research shows that in global flow meter market ultrasonic meters now account more than ten percent of the generated revenues.
From other flow meters ultrasonic flow meters have some sole advantages. Many ultrasonic flow meters are in clamp-on style. As per need clamp-on meters can easily be moved from one place to another. As meters are mounted on the outer side of the pipe that means there is no disturbance into the pipe. Ultrasonic flow meters have one or more paths. It is known that signal moves more rapidly when it travels with the flow, but signal slows down when it moves against the flow. The proportional to flow rate is the variation between two transit times.
Supplies of ultrasonic flow meter have been able to improve measurement accuracy by building flow meters with more than one path. With more paths extremely precise results can be acquired. Than also there are only few suppliers who offer meters with more paths.
