ABSTRACT:
This paper concerns both, a development of a software and a development of a peripheral for pressure and flow data acquisition in hydraulic research. The program was developed using Delphi language and the external communication was made by the computer’s parallel port. A simple and low cost peripheral can be assembled by the user with commercially available electronic components. For testing the equipment, pressure was determined using silicon transducers, and flow by means of an electromagnetic sensor. The program allows the user to choose time interval between reading and display average values on the screen at the end of a reading process. Data are stored in “.txt” format to be accessed by other computer applications.
Keywords: delphi, A/D converters, hydraulic, data acquisition.
