【Abstract】 The system built for automatic flow measurement is to meet the needs of flood controland water management. It consists of information collection, transmission, microcomputer, peripher-al equipment and a protection part. Having run for one year, it works well and gets the design goal.This paper centres on introducing such important techniques as rating and functioning the relation be-tween the discharge and water level of river gate, interface of microcomputer and peripheral equip-ment, how to protect the system from lightning and the manufacture of the type 2P- 5 lightning ar-rester board.更多还原
