A portable digital liquid density measurement system was designed. According to Archimedes principle that a sinkers buoyant force in some liquid is related with liquid density, the system proposed converted analog signal of a pressure sensor into digital signal which can be processed by AT89C52 microcontroller using ADHX711 with high accuracy. Temperature calibration was considered in data processing, which made it possible to accurately measure liquid density at different temperatures. Experiment results show that the method proposed is superior to traditional methods.
