recording surface

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.

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。
