ZB-LD electromagnetic flowmeter works:
ZB-LD electromagnetic flowmeter measurement principle is based on Faraday's law of electromagnetic induction. The flowmeter's measuring tube is a lined with insulating material non-conducting alloy short tube. The two electrodes are fixed to the measuring tube in the radial direction through the wall. The electrode tip is substantially flush with the inner surface of the liner. When the field coil is magnetized by bi-directional square wave, a magnetic field with a magnetic flux density B is generated in the direction perpendicular to the axis of the measuring tube. At this time, if a certain conductivity of the liquid flow through the measuring tube, the cutting force line induction electromotive force E. The electromotive force E is proportional to the magnetic flux density B, the product of the inner diameter d of the measuring tube and the average flow velocity V. The electromotive force E (flow signal) is detected by the electrode and sent to the converter via a cable. Converter will flow signal amplification process, can display the fluid flow, and can output pulse, analog current and other signals for the flow control and regulation. E = KBdV
Where: E ---- is the signal voltage between the electrodes (V)
B - magnetic flux density (T)
D - measuring tube diameter (m)
      V - average flow rate (m / s)
   Where K is a constant, the excitation current is constant, so B is constant, then by E = KBdV we can see that the volume flow Q is proportional to the signal voltage E, that is, the flow rate sensing signal voltage E and the volume flow Q into Linear relationship. Therefore, as long as the measurement of E can determine the flow Q, which is the basic working principle of electromagnetic flowmeter.
From E = KBdV, it can be seen that the parameters such as temperature, density, pressure, conductivity, liquid-solid composition ratio of liquid-solid two-phase fluid medium will not affect the measurement results. As for the flow state as long as the axis of symmetric flow (such as laminar or turbulent) will not affect the measurement results. So that the electromagnetic flowmeter is a true volume flowmeter. For the manufacturer and the user, as long as the actual water after the actual calibration can measure the volume of any other conductive fluid medium, without any correction, which is a prominent advantage of electromagnetic flowmeter, is any other flowmeter No. There is no activity and resistance flow in the measuring tube, so there is almost no pressure loss and a high reliability.
ZB-LD series electromagnetic flow meter instrument selection:
1, range range confirmation
General industrial electromagnetic flowmeter measured medium flow rate of 2 ~ 4m / s is appropriate, in special circumstances, the minimum flow rate should be not less than 0.2m / s, the maximum should not be greater than 8m / s. If the medium contains solid particles, the common flow rate should be less than 3m / s, to prevent the lining and the electrode of excessive friction; for viscous fluid, the flow rate can be selected greater than 2m / s, the larger flow rate helps to automatically remove the stick Stagnation of the role, is conducive to improving the measurement accuracy.
The size of the flowmeter diameter D can be determined according to the range of the above-mentioned flow rate V under the condition that the range Q has been determined. The value is calculated by the following formula:
Q = πD2V / 4
Q: flow rate (㎡ / h) D: pipe diameter V: flow rate (m / h)
The range of the electromagnetic flowmeter Q should be greater than the expected maximum flow value, and the normal flow value to slightly larger than the flow meter full scale 50 is appropriate.

ZB-LD電磁流量計工作原理：
ZB-LD電磁流量計測量原理是基于法拉第電磁感應定律。流量計的測量管是一內襯絕緣材料非導磁合金短管。兩只電極沿管徑方向穿通壁固定在測量管上。其電極頭與襯里內表面基本齊平。勵磁線圈由雙向方波脈沖勱磁時，將在與測量管軸線垂直的方向上產生一磁通量密度為Ｂ的工作磁場。此時，如果具有一定電導率的液體流經測量管，將切割磁力線感應出電動勢Ｅ。電動勢Ｅ正比于磁通量密度Ｂ,測量管內徑d與平均流速V 的乘積。電動勢Ｅ（流量信號）由電極檢出并通過電纜送至轉換器。轉換器將流量信號放大處理后，可顯示流體流量，并能輸出脈沖，摸擬電流等信號，用于流量的控制和調節。     E＝KBdV
式中:  E――――為電極間的信號電壓（V）
B――――磁通密度（T）
d――――測量管內徑（m）
      V――――平均流速（m/s）
   式中K，d為常數，由于勵磁電流是恒流的，故B也是常數，則由E＝KBdV可知，體積流量Q與信號電壓E成正比，即流速感應的信號電壓E與體積流量Q成線性關系。因此,只要測量出E就可確定流量Q，這就是電磁流量計的基本工作原理。
由E＝KBdV可知，被測流體介質的溫度、密度、壓力、電導率、液固兩相流體介質的液固成分比等參數不會影響測量結果。至于流動狀態只要符合軸對稱流動（如層流或紊流）就不會影響測量結果的。因此說電磁流量計是一種真正的體積流量計。對于制造廠和用戶來說，只要用普通的水實際標定后就可測量其他任何導電流體介質的體積，而不需作任何修正，這是電磁流量計的一突出優點，是其他任何流量計所沒有的。測量管內無活動及阻流部件，因此幾乎沒有壓力損失，并具有很高的可靠性。
ZB-LD系列電磁流量計儀表選型：
1、量程范圍確認
一般工業用電磁流量計被測介質流速以2～4m/s為宜，在特殊情況下，zui低流速應不小于0.2m/s，zui高應不大于8m/s。若介質中含有固體顆粒，常用流速應小于3m/s，防止襯里和電極的過分磨擦；對于粘滯流體，流速可選擇大于2m/s，較大的流速有助于自動消除電極上附著的粘滯物的作用，有利于提高測量精度。
在量程Q已確定的條件下，即可根據上述流速V的范圍決定流量計口徑D的大小，其值由下式計算：
Q=πD2V/4
Q:流量（㎡/h） D:管道內徑 V：流速（m/h）
電磁流量計的量程Q應大于預計的zui大流量值，而正常的流量值以稍大于流量計滿量程刻度的50為宜。
