流量仪表和传感器在现代工业生产中占有重要地位。为了进一步降低能源和原材料费用,除了需要在昂贵的石油、化工材料计量方面进一步提高精确度,对诸如冷却水、蒸汽一类低成本流体也提出了流量计量要求,以节约泵送费用,降低能耗。近年来,随着流量检测对象的广泛化,各种新装置如电磁式、超声波式和涡街流量传感装置得到较快的发展。与此同时,利用μp、μc的智能增进装置功能的开发也十分活跃。流量 Flow meters and sensors occupy an important place in modern industrial production. To further reduce the cost of energy and raw materials, in addition to the need to further improve the accuracy of expensive petroleum and chemical material metering, flow metering requirements have also been put forward for low-cost fluids such as cooling water and steam to save pumping costs and reduce energy consumption Consumption In recent years, with the wide range of traffic detection objects, various new devices such as electromagnetic, ultrasonic and vortex flow sensing devices have been developed rapidly. At the same time, the use ofμp, μc smart promotion device function is also very active. flow
