 測(cè)量原理        

The principle of electromagnetic flowmeter based on Fala's law of electromagnetic induction:

當(dāng)導(dǎo)電液體流過包圍在磁場(chǎng)中的測(cè)量管時(shí)，在流向和磁場(chǎng)二者相垂直的方向就會(huì)產(chǎn)生與平均流速V成正比的感應(yīng)電動(dòng)勢(shì)E。

When the conductive liquid flows through the surrounding the measurement in a magnetic field in the flow tube, and the two magnetic field perpendicular to the direction of produces and induced electromotive force is proportional to the average flow velocity of V E.

HN-LDG由傳感器和轉(zhuǎn)換器二部分組成，轉(zhuǎn)換器通過勵(lì)磁電纜將勵(lì)磁電流傳輸?shù)絺鞲衅鲀?nèi)部的線圈，從而在傳感器測(cè)量管內(nèi)產(chǎn)生磁場(chǎng)，流過測(cè)量管的導(dǎo)電液體因切割磁力線而產(chǎn)生感應(yīng)電動(dòng)勢(shì)，固定在測(cè)量管管壁二側(cè)的電極接收并通過信號(hào)電纜將該感應(yīng)電動(dòng)勢(shì)傳輸給轉(zhuǎn)換器，轉(zhuǎn)換器將該信號(hào)進(jìn)行濾波、放大、運(yùn)算、變換后，得出被測(cè)介質(zhì)的流量值，并輸出與流量測(cè)量值成正比的標(biāo)準(zhǔn)電流信號(hào)或頻率信號(hào)。

HN-LDG consists of a sensor and converter is composed of two parts, the converter will coil excitation current is transferred to the sensor through the exciting magnetic field sensor cable, resulting in the measuring tube, conductive liquid flow through the measuring tube for cutting magnetic induction electromotive force generated, the electrode is fixed on the measuring tube wall and two side receives the induction electromotive force transmission the signal cable to the converter, converter converts the signal filtering, amplification, operation, after transformation, the measured medium flow value, and outputs and flow measurement value is proportional to the standard current signal or a frequency signal.
