Design for High Precision Power Consumption Meter

This paper discuss the way to measure power consumption,propose the structural design,circuit design and relevant software development of a power consumption meter which can measure the corresponding power consumption while using fluid to cool equipment.Analyze its basic operation principle,the calculation of pipeline loss,the calculation for installation location of sensor,the heat capacity ratio and the calculation of the change of temperature based on fluid density.Also analyze the design for relevant controller,signal regulation and use XTR115 to output standard 4-20mA power signal.
