一、概述电磁流速仪是近代发展较快的一种新型测试水流的仪器,它克服了旋桨流速仪受泥沙、杂物影响无法工作的弱点,以其受水质影响小、传感器形式多样等特点,表现出顽强的生命力。但是目前使用的这类仪器尚未利用微机技术实现智能化,这样影响了仪器优点的充分发挥。例如,在原观测量中,指针式显示器受船体晃动、水流不稳的影响而无法读数或读数不准;在读取 I. Overview Electromagnetic flowmeter is a new type of rapid testing instrument developed in recent times. It overcomes the weakness that the propeller velocity meter can not work due to sediment and debris, and it has little influence on water quality and diversified sensors Features, showing tenacious vitality. However, the current use of such devices have not yet been using intelligent computer technology, thus affecting the full advantage of the instrument. For example, in the original observation, the pointer display by the hull rock, instability of the water flow can not be read or reading is not allowed; reading
