The present set-up is designed to study two types of differential pressure based flow measuring devices. One is an orifice meter and other is Venture meter. The set-up also facilitates the end user to calculate fluid discharge through it. By determining the co-efficient of discharge of these flow meter these can be used as a direct flow meter and can be installed in a fluid line. The apparatus consists of two pipe line emerging out from a common manifold. Both pipe line has been installed with a test section. One has venturi meter and other one has an orifice meter. A valve arrangement is given to operate any one selected test section at a time. Pressure taping from these flow meters are taken out to differential pressure transmitter. Present set-up is self-contained water re-circulating unit, provided with a sump tank, centrifugal pump etc. Water is pumped by means of centrifugal pump and passing through the test sections, it returns back to the sump which make the system re-circulating type. Flow control valve and by-pass valve are fitted in water line to conduct the experiment on different flow rates. Flow rate of water is measured with the help of flow sensor fitted in water line. The supplied set-up is complete in all respect. Only water supply and electricity supply is to be provided by the end user for running the set-up. The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of LabView. This software is compatible to interfacing unit designed by  Engineers. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.
