電磁流量計是目前在工業生產中使用最多的介質測量儀器之一,通過電磁流量計我們可以測量到介質的質量、流量等數據以分析生產過程是否正常。在工業環境中,電磁流量計一般應用于一些腐蝕性介質測量,所以在使用過程中需要定期對其進行保養維護,以確保其正常工作。

電磁流量計通電使用必須在電磁流量傳感器充溢液體靜止狀態下調整零點。投入運轉后亦要對于運用條件定時停流作零點查看;特別對堆積、易污染電極,富含固體的非清潔液,在運轉前期應多作查看,以確定正常查看周期。溝通激磁方法的電磁流量計與矩形波激比,更易發生零點漂移,因而更要留意查看和調整。

在電磁流量計停機之后,需要先測量一下電極間的電阻,然后斷開傳感器與轉換器間信號連線,測量儀器在充滿液體后是否處于制造廠規定值范圍內。每次測量的阻值都需要記錄保存,可以作為以后判別電磁流量計傳感器故障的依據。

Electromagnetic flowmeter is one of the most widely used medium measuring instruments in industrial production at present. Through electromagnetic flowmeter, we can measure the quality, flow rate and other data of medium to analyze whether the production process is normal. In the industrial environment, electromagnetic flowmeter is generally used in some corrosive media measurement, so it needs to be regularly maintained in the process of use, to ensure its normal work.

The zero point of the electromagnetic flowmeter must be adjusted when the electromagnetic flow sensor is filled with liquid. After put into operation, it is also necessary to check the zero point of the operation condition for timing stop flow. Especially for accumulated, easily contaminated electrode, rich in solid non-clean liquid, in the early period of operation should be more check, to determine the normal view period. The electromagnetic flowmeter of communicating excitation method and rectangular wave excitation ratio are more prone to zero drift, so it is more important to pay attention to check and adjust.


After the electromagnetic flowmeter stops, it is necessary to measure the resistance between the electrodes first, and then disconnect the signal connection between the sensor and the converter, so as to measure whether the instrument is in the range specified by the manufacturer after it is filled with liquid. The resistance value of each measurement needs to be recorded and saved, which can be used as the basis for judging the faults of electromagnetic flowmeter sensors in the future.
