电磁流量计的结构主要由磁路系统、测量导管、电极、外壳、衬里和转换器等部分组成。
The structure of electromagnetic flowmeter is mainly composed of magnetic circuit system,measuring duct,electrode,shell,lining and converter.
特点:
Characteristic:
1、测量不受流体密度、粘度、温度、压力和电导率变化的影响;
2、测量管内无阻碍流动部件,无压损,直管段要求较低。对浆液测量有独特的适应性;
3、合理选择传感器衬里和电极材料,即具有良好的耐腐蚀和耐磨损性;
4、转换器采用新颖励磁方式,功耗低、零点稳定、精确度高。流量范围度可达150:1;
5、转换器可与传感器组成一体型或分离型;
6、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;
7、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;可显示正、反流量,并具有多种输出:电流、脉冲、数字通讯、HART;
8、转换器采用表面安装技术(SMT),具有自检和自诊断功能;
9、测量精度不受流体密度、粘度、温度、压力和电导率变化的影响,传感器感应电压信号与平均流速呈线性关系,因此测量精度高。
10、测量管道内无阻流件,因此没有附加的压力损失;测量管道内无可动部件,因此传感器寿命极长。
11、由于感应电压信号是在整个充满磁场的空间中形成的,是管道载面上的平均值,因此传感器所需的直管段较短,长度为5倍的管道直径。
12、转换器采用国际最新最先进的单片机(MCU)和表面贴装技术(SMT),性能可靠,精度高,功耗低,零点稳定,参数设定方便。点击中文显示LCD,显示累积流量,瞬时流量、流速、流量百分比等。
13、双向测量系统,可测正向流量、反向流量。采用特殊的生产工艺和优质材料,确保产品的性能在长时候内保持稳定。
1.The measurement is not affected by the changes of fluid density,viscosity,temperature,pressure and conductivity.
2.There are no obstructive flow components,no pressure loss in the measuring tube,and the requirement of straight pipe section is low.It has unique adaptability to slurry measurement.
3.Reasonable selection of sensor lining and electrode materials,that is,good corrosion resistance and wear resistance;
4.The converter adopts a novel excitation mode with low power consumption,zero stability and high accuracy.The flow range can reach 150:1.
5.The converter can be integrated or separated from the sensor.
6.The converter uses 16-bit high-performance microprocessor,2x16LCD display,convenient parameter setting and reliable programming.
7.Flowmeter is a bidirectional measurement system with three integrators:total forward,total reverse and total difference.It can display both positive and negative flow,and has a variety of outputs:current,pulse,digital communication and HART.
8.The converter adopts surface mounting technology(SMT),which has self-inspection and self-diagnosis functions.
9.The measurement accuracy is not affected by the changes of fluid density,viscosity,temperature,pressure and conductivity.The induction voltage signal of the sensor has a linear relationship with the average velocity of flow,so the measurement accuracy is high.
10.There is no obstruction in the measurement pipeline,so there is no additional pressure loss;there is no movable parts in the measurement pipeline,so the sensor has a very long life.
11.Because the induction voltage signal is formed in the whole space filled with magnetic field and is the average value on the pipeline surface,the straight pipe section needed by the sensor is shorter,and the length is five times the diameter of the pipeline.
12.The converter adopts the latest and most advanced MCU and SMT technology in the world.It has reliable performance,high precision,low power consumption,stable zero point and convenient parameter setting.Click on Chinese to display LCD,showing cumulative flow,instantaneous flow,flow rate,flow percentage,etc.
13.Two-way measurement system can measure forward and reverse flow.Special production technology and high-quality materials are adopted to ensure that the product performance remains stable in the long run.
