为了提高液位定量管中液面检测精度.设计了一套检测装置,精确测量液面经过光电检测器的过程中,光电信号的变化特征曲线.%In order to improve the detection accuracy of the liquid level in the liquid level quantitative tube. A set of testing device is designed to measure the change characteristic curve of the photoelectric signal when the liquid level passes the photoelectric detector.
