摘　　要：根据第15届流量测量国际会议(FLOMEKO2010)概况,讨论国际流量测量界关注的热点及流量测量技术和仪表的发展趋势。对于超声波流量计,主要研发应用于火炬气的仪表,具有自诊断功能的仪表,以及用于大水轮机的仪表。对于热式流量计,推出终端用户收费计量燃气表,研发医用一次性微流量传感器,探索不受气体成分变化影响的仪表。对于电磁流量计,开发测量液态金属和含铁磁性物质液体的仪表。论述了高速喷嘴、文丘里流量计、层流流量计的技术发展方向。According to the 15th International Flow Measurement Conference survey, the focus by the international flow measurement academia and the flow measurement technology and development trend of the instrument is discussed. For the ultrasonic flow-meter, it is focus on the instrument for flare gas with self-diagnosis function, as well as the instrument used for large diameter water turbine. For the thermal flow-meter, end user charged gas-fired meter is designed, and disposable micro flow-rate sensor for medicine is developed, and the instrument without influence by the gas composition varcation is also developed; and for electromagnetic flow-meter, the instrument for measuring liquid metal and liquid with ferric contained magnetic material is developed. The development trend is discussed for the high speed nozzle, venturi flow-meter and laminar flow-meter.
