Measuring the velocity and flow of fluids, both liquids and gases, has been a daily issue since the beginning of human civilization. Water clock was, for instance a tool used in ancient land of Persia that worked based on measuring the volume of water. In addition, industrial development requires the use of new technologies that are consistent with the methods of measurement of fluid flow and velocity, and therefore various flow meters have been developed since the eighteenth century (e.g. gas flow measuring tools in tubes, and velocity measurement in airplanes and other flying devices). In the present work, an interactive device has been made and presented to teach instruments and methods of measuring the velocity and flow of gases. This device consists of 4 sections; gas meter, anemometer, orifice plate, and Pitot tube. The mentioned project will be used as an educational device at the Science and Technology Museum. One of the main goals of the Science and Technology Museums is the growth and upbringing of the citizens. This device represents technology education which is based on interaction with the visitors of the Science and Technology Museum.
