EXPERIMENTAL, AND THEORETICAL DETERMINATION OF CHARACTERISTICS OF DALL FLOW TUBES AND A COMPARATIVE STUDY OF THEM WITH THE OTHER. FLOW MEASURING DEVICES

Abstract

Invention is always dynamic. With the in. crease of scientific knowledge, the industrial prod1ts are getting new shapes to suit the increasing demands of greater accuracy an better working. There is also keen competition amongst the industrial enterprises to put in the market their products having better usage to mankind. To that and they use the latest techniques of design and production to win the market. The same is also true in case of fluid flow measuring devices. This thesis work deals with the latest type of different-tial pressure flow measuring device know as ' Dali Flow Tube'. The work embodies the characteristic study of this new device and a comparative study of it with other types of differential pressure producing flow metering devices.. The author hopes that this work may give some informations to those who are interested in fluid flow metering problems.
