Liquid Level And Speed Measuring System Based On Singlechip

Liquid level measuring is related with robotization closely, and almost spreads over all fields of producing and living. In recent years, because of the development and application of new measure principle and micro-electronics technique, the liquid level measuring instruments become more miniature and more intelligentized. They gradually realize fault diagnosis and alarm, high precision, high reliability, high safety and multi-function.This system is developed by this paper to measure liquid level automatically and liquid speed accurately. The system transports the detecting liquid speed signal of lower machine to the upper machine, and the signal of every lower machine is displayed around. When the liquid level of lower machine is under the given lower limit or the liquid speed is much faster or lower, the alarm will be made in the upper machine and corresponding lower machine to remind the paramedic to deal with it.This system, whose kernel is 8051, detects liquid level, liquid speed and whether has bubble or not, thereby can be displayed and alerted. At the same time, it delivers data of lower machine to upper machine in the way of wireless...
