User Survey by Flow Research Finds Shift to New-Technology Flowmeters.WAKEFIELD Wakefield, estate, United States Wakefield, family estate of George Washington, on the Potomac River, E Va.; part of the George Washington Birthplace National Monument (see National Parks and Monuments, table). , Mass. -- A new survey of flowmeter See flow meter. users shows a shift away from traditional flowmeters and towards new-technology flowmeters. New-technology flowmeters are those introduced since 1950, including Coriolis Coriolis can refer to:
ul·tra·son·ic adj. 1. , vortex, and thermal. Traditional flowmeters include differential pressure (DP), turbine turbine, rotary engine that uses a continuous stream of fluid (gas or liquid) to turn a shaft that can drive machinery. A water, or hydraulic, turbine is used to drive electric generators in hydroelectric power stations. , positive displacement A positive displacement meter is a type of flow meter that requires the fluid being measured to mechanically displace components in the meter in order for any fluid flow to occur. A diaphragm meter, with which most homes are equipped, is an example of a positive displacement meter. , and variable area. New-technology flowmeters have been gaining ground on traditional flowmeters in the past few years because they typically have higher accuracy, lower maintenance, and no moving parts Moving parts are the components of a device that undergo continuous or frequent motion, most commonly rotation. "Parts" only include the mechanical components which does not include fuel, or any other gas or liquid. . In the survey, users were asked, for each flowmeter type, whether their firm had purchased or specified that type in 2004. They were also asked for each flowmeter type whether their firm expects to purchase or specify that type of flowmeter in 2008. In the case of new-technology flowmeters, the percentage of respondents In the context of marketing research, a representative sample drawn from a larger population of people from whom information is collected and used to develop or confirm marketing strategy. expecting to purchase or specify these types is greater in 2008 than it is in 2004. And for traditional flowmeters, the corresponding percentage is either flat or declining between 2004 and 2008. For Coriolis flowmeters, just over 40 percent of respondents said that Coriolis flowmeters were purchased or specified at their plant in 2004. When asked about the future, 47 percent of respondents expect that Coriolis flowmeters will be purchased or specified at their plant in 2008. The survey shows similar results for magnetic, ultrasonic, vortex, and thermal flowmeters. Traditional flowmeters present a different picture. While 36 percent of respondents say that turbine flowmeters were purchased or specified at their plant in 2004, less than 32 percent expect that this will be the case in 2008. The survey shows similar results for positive displacement flowmeters. The results for users of differential pressure and variable area flowmeters are almost flat, although both show a slight decline in the percentages between 2004 and 2008. The Internet-based survey was conducted in August 2005 by Flow Research, together with Venture Development Corporation. The results were published in January 2006 as a study called "Worldwide Survey of Flowmeter Users, 2nd Edition" (http://www.flowresearch.com/User_Survey/welcome.htm). The study had 586 participants.
