This paper gives an introduction to the development of a multi\|channel fluid flux real\|time monitoring device. It is based on the application of Intel 8751 single chip microcomputer. The device applies analog multiplexer to monitor 5 revolving flowmeters in 5 channels respectively, implements frequency measuring using Intel 8253 Timer/Counter. Applications have proved that the device completes fluid flux measurement and results display in real time. The function index of the application system meets the design requirements. The technology can be applied to other frequency measuring systems.
