摘　　要：简述了流量测量及仪表技术的发展历程及背景,介绍了节流式差压、靶式、涡街、容积式、浮子和涡轮等传统流量计以及电磁、超声波、科里奥利质量和激光等新型流量计的原理和特点。分析指出,在全球倡导节能减排理念、传统流量计局限性日益突出以及物联网技术不断发展的背景下,流量计产业将向着高精度、高可靠性、智能化和远程化方向发展。The developing history and background of flow measurement and flow instruments technology are described briefly. The principles and features of traditional flow meters, such as throttle differential, target type, vortex, volumetric, float and turbine, etc. , and novel flow meters, such as electromagnetic, ultrasonic, Coriolis mass and laser, etc. , are introduced. The analysis indicates that, under the background of energy saving and emission reduction, limitations of traditional flow meter becoming increasingly prominent and the development of the IoT technology, high accuracy ,high reliability and intellectualization and telemetry are the developing trends of flow meter industry.
