In universities or industrial institutions, the need for enhanced laboratory instrumentation has always been identified to increase the quality of laboratory experiments. As a solution to some of these shortcomings, a low-cost computer aided pumps testing system has been developed which can easily be adapted to varying demands of laboratory applications. The computer aided multi-purpose pumps testing system basically consists of pumps characteristics in different configuration. The system developed by upgrading the old system by implementing a data acquisition system with module based control software called COMPUTE (COmputer Multi-purpose PUmps Testing) on a personal computer located in hydraulic laboratory of mechanical engineering department in Eastern Mediterranean University. COMPUTE is flexible user friendly software that has been developed for performing measurements calculation, plotting and automating the operation of laboratory instruments. It provides the use of a number of modules to control various experiments in hydraulic laboratory at the same time such as a minor, majore loses test machine.
