Flowmeter survey reveals shift toward new-technology devices
Flowmeter users are turning away from traditional devices and towards new-technology instruments, according to a recent survey by Flow Research Inc. New technology flowmeters include those introduced since 1950, among them Coriolis, magnetic, ultrasonic, vortex, and thermal units, the research firm says.
Flowmeter users are turning away from traditional devices and towards new-technology instruments, according to a recent survey by Flow Research Inc . New technology flowmeters include those introduced since 1950, among them Coriolis, magnetic, ultrasonic, vortex, and thermal units, the research firm says. Traditional devices include differential pressure (DP), turbine, positive displacement, and variable area types. New-technology products have been gaining in popularity because they offer greater accuracy and lower maintenance and have no moving parts. More than 500 users participated in the survey.
In the survey, users were asked, for each flowmeter type, if they had purchased or specified that type in 2004 and if they anticipated purchasing or specifying that type in 2008. The results indicated that more users expect to buy or specify new-technology devices in 2008 than in 2004. The percentage of those buying or specifying traditional units is flat or declining between 2004 and 2008.
More than 40% of respondents said they bought or specified Coriolis meters in 2004; 47% plan to do so in 2008. Results for other new-technology types were similar. On the traditional meter side, 36% said they purchased or specified turbine meters in 2004; only 32% anticipated doing so in 2008. Similar results were obtained for positive displacement flowmeters. Results for DP and variable types were flat to slightly declining between 2004 and 2008.
One noteworthy finding, said the study report, was that more DP meters are installed in plants than any other type, indicating that the move to new-technology devices likely will be a gradual one.
