Hi

Can anybody suggest me a good book for starting with Level basics and Level control?

Thanks in advance.

The chapter on level control in my book, the Instrumentation Reference Book, 3rd Edition is pretty good.

Actually, though, you can get a lot from the following article I produced recently for Control:
http://www.controlglobal.com/articles/2007/022.html "First the application, then the product"

You can also download PDF of a handy reference chart from the article called "The level Measurement Continuum" which allows you to see visually what kinds of devices work well in what sorts of applications.

http://www.controlglobal.com/Media/MediaManager/a rticle_022_level.pdf

If you want to go deeper into the subject, David Spitzer and I have written several books in our "Consumer Guide to..." series about level measurement instrumentation, including comparison charts that allow you to compare the
specifications of most manufacturers' products, as well as see who private labels for whom.

This search on http://www.controlglobal.com pulls up several excellent white papers as well as more articles on level measurement: (mind the line-wrap...) http://www.controlglobal.com/search.html?sp-q=level%20measurement& sp-p=all&s
