摘要
本文介绍了实验室内用于测量流量和含沙量的超声波液位测定系统.此系统采用气介式方案,选用复合材料高频换能器作为超声波发射\接收器件,结构简单,静态测量时测量误差在150mm范围内不超过1mm,并可与微机进行远距离通讯.
Presented is a laboratory adapted ultrasonic liquid level measuring system to be used for flow and silt content measurements.We use high frequency piezo-composite transducers to transmit and receive ultrasound through the air.The system is very simple,has high resolution and can communicate with a computer through long distance.
