 電磁流量計在現代自動化工業生產中非常重要,不少工廠已經在普及使用中。設備在我們使用過程中,難免會出現一些故障問題,電磁流量計在運行過程中的故障主要有外因和內因兩種,想要及時解決問題的話,就必須要了解其故障原因。


當我們發現流量測量值與實際值不符時,首先要檢查變送器的電路板問題。液體流速過低時,被測液體中含有微小氣泡,氣泡上升在管道上方逐漸會萃,則液體暢通流暢面積發生變化,氣體多時還會產生干擾信號,影響丈量正確度。另外,信號電纜連接不好或使用過程中電纜的絕緣機能下降也會引起測量值不準的問題。在這個時候,可以選擇更換電路板以解決問題。


當出現輸出信號超滿度量程的現象時,一般原因在于信號電纜接線接錯或者斷開,另外轉換器的參數設定不準確也會引起該現象的發生。對于這個問題我們應該檢查信號回路連接是否正常,若信號回路斷開,輸出信號將超滿度值,應該將線路重新接好。

Electromagnetic flowmeter is very important in modern automation industry and many factories have been widely used. In the process of our use of the equipment, there will inevitably be some fault problems, electromagnetic flowmeter in the process of running the fault mainly has two kinds of external cause and internal cause, want to solve the problem in time, it is necessary to understand the cause of the fault.

When we find that the measured flow value does not match the actual value, we must first check the transmitter circuit board problem. When the liquid flow rate is too low, the measured liquid contains tiny bubbles, which will gradually emerge when the bubbles rise above the pipe. Then, the smooth and smooth area of the liquid will change, and when the gas is too long, interference signals will be generated, affecting the accuracy of measurement. In addition, the signal cable connection is not good or the insulation function of the cable in the process of use will also cause the measurement value is not accurate. At this point, you can choose to replace the circuit board to solve the problem.


When the output signal overfills the range, it is usually caused by wrong connection or disconnection of the signal cable. In addition, inaccurate parameter setting of the converter may also cause this phenomenon. For this problem, we should check whether the signal loop connection is normal. If the signal loop is disconnected, the output signal will exceed the full value, and the circuit should be reconnected.
