Context[edit]

The intro should say what it is, what it does, when it is used. NickelShoe 16:38, 14 February 2006 (UTC)[reply]

Multiple problems with this article. Doppler is not a 'recent' developement, as far as I know it is the oldest ultrasonic flowmeter technology and mostly discredited or at least highly unpopular with most knowledgable flowmeter engineers in industrial applications. I cannot speak for their use in medical applications. There are also at least two other ultrasonic flowmeter technologies not mentioned, correlation tag and transflection methods. The line about ultrasonic flowmeters being affected by temperature, viscosity and density is very misleading. There is at least one ultrasonic flowmeter system that is viscosity, temperature and density independent. Inexpensive to use? Another misleading line, ultrasonic flowmeters range in cost from $1000 to >$100,000. Principles section ignores all systems other then transit time.

Why is there a section on doppler systems but not any other? It appears that the article is written or has been edited by someone who either has knowledge of only or bias towards doppler. As someone who has twenty years experience in multiple ultrasonic flowmeter technologies, my opinion is this article is at best highly misleading and uninformed. At worst, it is complete rubbish and should be removed. This is precisely the kind of article that gives wikipedia such a poor reputation as a serious reference. —Preceding unsigned comment added by 83.147.135.60 (talk) 10:43, 9 April 2011 (UTC)[reply]
