Flow Measurement and Control Based on MCS-51 Single Chip Computer Ning Xinguo (Lect.,Dept. of Mechanical Engineering, WUT, Wuhan 430070, China.)Design of flowmeter based on MCS-51 single chip computer is introduced in this paper. The flowmeter has many functions such as pre-setting parameters, displaying data, printing results, on-line controlling flow and so on. Connected with flow transducer outputting impulsive signal, it can measure the instant flow, accumulative flow, mass flow of the liquid, the gas or the vapour.: 8031 single chip computer; flow measurement; compensation of measurement
