一、概述 YR—A型液面计适用于各种导电、非导电液位的测量。但该仪器,如用作水工试验室浪高的测量,则其传感部分就显得异常笨重,难以满足经常性装卸和标定的要求,入水棒径也过粗,影响测量精度及流态。本文总结了对传感器结构的改进,改进后的传感器经过多年来的使用证明具有轻便、灵 First, an overview YR-A-type liquid level gauge for a variety of conductive, non-conductive liquid level measurement. However, if the instrument is used as a hydraulic laboratory wave height measurement, the sensing part becomes very bulky and difficult to meet the requirements of regular loading and unloading and calibration. The water inlet rod diameter is also too coarse, which affects the measurement accuracy and flow pattern. This article summarizes the sensor structure improvements, the improved sensor after years of use proved to be lightweight, Ling
