一、进口压缩空气流量计概述

压缩空气流量计，在任何工业现场中都有应用，主要用于压缩空气的计量，压缩空气贸易结算，压缩空气计量能耗管理和成本控制等。压缩空气流量计量是工业过程计量中重要的环节，技术选型更是一件很慎重的事情，首先必须了解现场工艺流体的性质，充分考虑到精确度、测量环境、重复性、测量范围、压力损失和响应时间等因素，才能对选型作出正确判断。随着传感器技术和计算机技术的进步，压缩空气流量测量将向高可靠性、广泛适应性等方面发展。

压缩空气流量计，安装过程中前后直管段是否满足要求，管道和流量计之间水平或竖直，管道周围是否便于产品维护，还要考虑到现场的温度，是否有电磁干扰，是否存在振动。经济上：如工厂在线监测选择流量计，要考虑减少压损，节约能耗、在大口径管道上应使用插入式压缩空气流量计，减少管路安装等，以节约成本。另外，应尽可能保证压缩空气的洁净，以免影响测量精度，因此在气体质量不好或者测量小流量时应加装油水分离器、干燥设备等净化设备来保证气体的洁净。

美国威盾VTON品牌的进口压缩空气流量计，产品主要可测量：压缩空气的计量，目前广泛用于石汽车制造、机械、轻工、纺织、电子、食品、医药、玻璃制造、能源、环保等行业。

Compressed air flow meters are widely used in any industrial field, mainly for measuring compressed air, settling compressed air trade, managing compressed air metering energy consumption, and cost control. Compressed air flow measurement is an important part of industrial process measurement, and technology selection is a very cautious matter. Firstly, it is necessary to understand the properties of the process fluid on site, fully consider factors such as accuracy, measurement environment, repeatability, measurement range, pressure loss, and response time, in order to make a correct judgment on selection. With the advancement of sensor technology and computer technology, compressed air flow measurement will develop towards high reliability and wide adaptability.

During the installation process of compressed air flow meters, whether the front and rear straight pipe sections meet the requirements, whether the pipeline and flow meter are horizontal or vertical, whether the surrounding area of the pipeline is convenient for product maintenance, as well as considering the temperature on site, whether there is electromagnetic interference, and whether there is vibration. Economically, when selecting flow meters for online monitoring in factories, consideration should be given to reducing pressure loss, saving energy consumption, using plug-in compressed air flow meters on large-diameter pipelines, and reducing pipeline installation to save costs. In addition, it is necessary to ensure the cleanliness of compressed air as much as possible to avoid affecting measurement accuracy. Therefore, when the gas quality is poor or when measuring small flow rates, purification equipment such as oil-water separators and drying devices should be installed to ensure the cleanliness of the gas.

VTON's imported compressed air flow meters are mainly used for measuring compressed air, and are currently widely used in industries such as automobile manufacturing, machinery, light industry, textile, electronics, food, medicine, glass manufacturing, energy, and environmental protection.
