Features and advantages of electromagnetic flowmeters
2011-10-12 15:33:16

随着科学技术 在迅速的 发展 起来 ,新型的 电磁 流量 仪表 也紧跟着 涌现 了出来 ,性能各异,品种繁多,使用条件 产品的各种优质 技术参数 也各尽不 In recent years, with the rapid development of science and technology , new types of electromagnetic flow meters have emerged , with different performances and varieties, and different use conditions and various high-quality technical parameters of products . 根据以往所使用的各种流量仪表的实际应用情况、安装难度、性能价格比等 问题进行了认真地 总结问题所在、 分析比较 失误 反复进行 论证 一系列程序后 ,认为电磁流量计具有 以下几大特点与优势: Jinhu Dongxiang Instrument Co., Ltd. carefully summarized the problems, analyzed the errors and repeatedly demonstrated a series of procedures based on the actual application situation, installation difficulty, performance price ratio and other issues of various flow meters used in the past . The electromagnetic flowmeter has the following characteristics and advantages:

反应灵敏、线性好、精确度高、在测量过程中,不受被测介质的温度、流体密度 黏度。 1. Sensitive response, good linearity, high accuracy, during the measurement process, it is not affected by the temperature, fluid density and viscosity of the measured medium . 不但 精度高 线性好 ,而且运 还比较的 稳定, 这就很在很大程度上 提高了计量的准确性和数据的可信度,克服了 以往 仪表运行不太稳定,由此而造成了测量数据不可信的问题。 The advantages of factors such as pressure and conductivity changes; the electromagnetic flowmeter not only has high accuracy and good linearity , but also operates relatively stably, which greatly improves the accuracy of the measurement and the credibility of the data. It overcomes the problem that the previous meter operation is not stable, which causes the problem of unreliable measurement data. 对电磁流量计的 比对,误差均在控制范围之内,增强了对 电磁流量计 信任程度, 因此也 结束了按水泵的性能曲线计算水量的不科学计量方法, 真正意义上的 做到 电磁流量计 采集数据为准, 从而也 避免了人为 造成的不精确度; After many on-site comparisons of electromagnetic flowmeters , the errors are within the control range, which enhances the trustworthiness of the electromagnetic flowmeters , so it also ends the unscientific measurement method of calculating the water volume according to the performance curve of the pump. The above is based on the data collected by the electromagnetic flowmeter , which also avoids human-made inaccuracies;

测量管内无阻碍流动部件,无压损,直管段要求较低; 电磁流量计结构简单, 传感器 没有 任何一个可以移动 部件, 因而也就 不存在因 机械运动磨损或 杂质缠绕 等内部因素所 产生的测量误差或仪表故障 ,因 而也大大的降 了电磁流量计的 故障率, 从而也 大大减少 维修量, 真正意义上做到了 大量人力 物力 节约 程度了; 2. There are no obstructing flow parts in the measuring tube, no pressure loss, and low requirements for straight pipe sections; the structure of the electromagnetic flowmeter is simple, and the sensor does not have any movable parts, so there are no internal factors such as wear due to mechanical movement or entanglement of impurities. The resulting measurement error or instrument failure country also greatly reduces the failure rate of the electromagnetic flowmeter , thereby greatly reducing the amount of maintenance, and in the true sense has achieved a lot of labor and material savings .

电磁流量计 系列公称通径DN15 DN3000 3. Nominal diameter of electromagnetic flowmeter series DN15 ~ DN3000 . 传感器衬里 着相应的 多种选择; 具有多种电路接口, 因此更大程度上的 方便 与计算机或数据采集终端联接 因此也真正意义上 实现数据采集、分析、管理 自动化 There are corresponding choices for electrode materials and sensor linings ; there are also multiple circuit interfaces, so it is more convenient to connect with a computer or data acquisition terminal , so it also truly implements data collection, analysis, and management. Automation

电磁流量计 转换器可 与传感器组成一体型或 分离型; 5. The electromagnetic flowmeter converter can be integrated or separated with the sensor ;

电磁流量计 转换器采用16 位高性能微处理器, 2x16LCD 显示,参数设定方便,编程可靠; 6. The electromagnetic flowmeter converter adopts a 16 -bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting and reliable programming;

流量计为双向测量系统,内装三个积算器:正向总量、反向总量及差值总量;可显示. 7. The flow meter is a two-way measurement system with three totalizers: forward total, reverse total, and difference total; it can be displayed. Zhuang, anti-flow, and has multiple outputs: current, pulse, digital communication, HART ;

电磁流量计 转换器采用表面安装技术(SMT) ,具有自检和自诊断 功能; 8. The electromagnetic flowmeter converter adopts surface mounting technology (SMT) , which has the functions of self-test and self-diagnosis ;
正确使用、维护电磁流量计 就更 为重要 Of course, the correct use and maintenance of electromagnetic flowmeters is even more important .

测量原理是法拉第电磁感应定律,传感器主要组成部分是:测量管、电极、励磁线圈、铁芯与磁轭壳体。 The measuring principle of the electromagnetic flowmeter is the Faraday's law of electromagnetic induction. The main components of the sensor are: a measuring tube, an electrode, an excitation coil, an iron core and a yoke housing. It is mainly used to measure the volumetric flow of conductive liquids and slurries in closed pipes. Including strong corrosive liquids such as acid, alkali and salt. 广泛应用于石油、化工、冶金、纺织、食品、制药、造纸等行业以及环保、市政管理,水利建设等领域。 Jinhu Dongxiang Instrument Co., Ltd.'s new products have been widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
