摘要
翻斗式自记流量计从工作原理的角度看,属于容积式流量计的一种,但从应用范围看,又与目前各种形式的容积式流量计均有所不同。目前传统的容积式流量计主要应用于有压管道情况,而翻斗式自记流量计主要应用于各种无压、低水头、小流量的地表和地下径流的监测。针对水文科学中有关无压、低水头、小流量的地表和地下径流的监测手段较为落后的局面,在分析翻斗式自记流量计基本构成、工作原理的基础上,对其制作工艺、误差及主要应用情况进行了阐述,旨在能够提高我国水文监测的水平。
Tipping bucket and self-recording flow meters belonged to one of flow meters based on volumetric method, but were different from normal. Normal or traditional flow meters mainly applied to pressured pipes at present, and yet tipping bucket and self-recording flow meters mainly applied to monitoring ground and surface runoff which were none-pressured, low water head or small flow rate. Based on thestructure, work principle and application areas of tipping bucker and self-recording flow meters, the making course and notices were introduced.
