产品特性   product features

1、EMF5000易博体育app官网下载结构简单,无转动部件,因而无摩擦,工作寿命长,计量精度高,性能可靠。

1, the EMF5000 electromagnetic flowmeter has the advantages of simple structure,No rotary parts, So there is no friction, Long working life, High precision measurement, Reliable performance.

 

2、传感器测量管中无节流和阻流部件,因此无附加压力损失,不存在堵塞问题,易博体育app官网下载测量含有悬浮物、固体颗粒、纤维等的两相流(如泥浆、污水、矿浆、纸浆、等粘性较大的浆液)。

2, the sensor measuring tube without throttle and choke component, Therefore, no additional pressure loss, No blocking problem, Suitable for measuring the containing suspended matter, Solid particles, Two phase flow fiber etc. (such as mud, sewage, slurry, pulp, and viscosity of the slurry).

 

3、由于信号在整个充满磁场的空间中形成,它是管道截面上的平均值,因此从而电极平面至传感器上游端平面间所需直管段相对较短,长度为10×D(D为管道的内直径)。

3, because the signal is formed in the magnetic field in full space, It is the average cross section of the pipeline, Therefore thus electrode plane to the sensor upstream the end plane straight pipe section with relatively short, Length of 10 × D (D is the internal diameter of the tubes).

 

4、EMF5000易博体育app官网下载无机械惯性、反应灵敏、可测量瞬时脉动流量,也可与单元组合仪表、计算机配套组成各种主动检测、调节系统和程控系统。

5、传感器输出信号是一个与平均流速成精确线形联系的电动势,并且测量结果与液体的温度、压力、密度、粘度、电导率(不小于最低电导率)等物理参数无关,如用水标定的流量计同样易博体育app官网下载其它介质的流量计量,无压力损失无需修正。因此测量精度高、工作可靠。

5, the output signal of the sensor is an exact linear relation with the average velocity of the electromotive force, And the measurement results and the temperature of the liquid, Pressure, density, viscosity, Conductivity (not less than the minimum conductivity) independent physical parameters, Such as water flow metering flowmeter calibration is also applicable to other media, No pressure loss without correction. Therefore, high measuring precision, reliable work.

四、工作原理  work principle

    EMF5000易博体育app官网下载原理是基于法拉第电磁感应定律。流量计的测量管是一内衬绝缘原料的非导磁合金短管。两只电极沿管径方向穿通管壁固定在测量管上。其电极头与衬里内表面基本齐平。励磁线圈由双向方波脉冲励磁时,将在与测量管轴线垂直的方向上发生一磁通量密度为B的工作磁场。此时,如果具有肯定电导率的流体流经测量管,将切割磁力线感应出电动势E。电动势E正比于磁通量密度B,测量管内径D与平均流速v的乘积,电动势E(流量信号)由电极检出并通过电缆送至转换器。转换器将流量信号放大处置后,可显示流体流量,并能输出脉冲,模拟电流等信号,用于流量的操纵和调节。
