If your keyword flowmeters is a common one, or if it has multiple other meanings, you could end up with a lot of irrelevant hits. And if your keyword is a subject about which you desire information, you don't need to see it repeated over and over. It is the information about that word that you're interested in, not the word itself.
Do you want broad information on flowmeters? Are you looking for something very specific or perhaps a unique product? Are you looking for a narrow aspect of a topic with a huge Web presence? When you search, are you overwhelmed by too many or off-target results?
