Abstract—In this study, an FPGA-based monitoring system that can analyze the characteristics of an automobile cooling system and various fluid systems was implemented. The system can simultaneously measure changes in the temperature, flow rate, and pressure of a fluid flowing inside a pipe. Furthermore, the measured data can be displayed on a computer screen in real time so that changes in the fluid’s condition can be observed and recorded. The cooling efficiency of the system was measured using contact and noncontact temperature sensors. A 24-bit analog-to-digital converter was used for accurate temperature measurements. The system was also constructed using a digital semiconductor pressure gauge and a turbine flow meter. The FPGA-based system consists of a temperature IP, a flow IP, a pressure IP, an LCD IP, and a communication IP.
