热式流量仪表市场类型和应用

Marketing Style and Application of Thermal Flow Instruments

近年来,我国热式流量仪表受到各界关注。从近几届多国仪器展览会参展厂商统计一个侧面考察市场扩展动态,估计了国内生产热式流量仪表的规模。列出热式仪表类型谱系图,阐述了各型号的原理特点和应用领域,最后概述了不同型号仪表应用于半导体、分析仪器采样、公用事业污水治理和环保废气排放监控等典型实例。

In China, all circles have focused on thermal flow instruments in recent years. The paper investigates the marketing expanding trend from statistics of exhibits presented in MICONEX these years, and estimates the domestic productive scale of thermal flow instruments. Pedigree diagram of thermal flow instruments is listed. The principle features of various models and their applications are expounded. Finally, the applications of different kinds of flow instruments in semiconductor, sampling of analytic instrument, utilities, sewage treatment, and gas exhaustion monitoring for environmental protection are described.
