Design of low power consumption intelligent metal tube rotameter

In this paper a design of a novel metal tube rotameter is presented. The system structure in which MSP430 chip microcomputer holds the key position is introduced to lower the power.Parts of the system such as signal detecting,temperature-pressure compensation,LCD display,man-machine interface and accumulative flow store are expatiated upon.Key points of software design and main program processing are also presented.The performance of the rotameter is satisfying in use.
