產(chǎn)品簡介 / PRODUCT INTRODUCTION

科恩科KNKE電磁流量計是一種常用的流量測量儀器,用于測量液體或氣體在管道中的流量。它通過感應(yīng)電磁場來測量流體的流量,利用法拉第電磁感應(yīng)定律,在導(dǎo)電介質(zhì)(如水、污水等)中通過兩個電極產(chǎn)生磁場,當(dāng)導(dǎo)電介質(zhì)在磁場中流動時,會在兩個電極間產(chǎn)生感應(yīng)電動勢,這個感應(yīng)電動勢與介質(zhì)的流速成正比,從而實(shí)現(xiàn)了流量的測量。

電磁流量計的工作原理是利用液體或氣體中帶電顆粒的運(yùn)動狀態(tài)改變磁場的感應(yīng)電動勢,通過檢測感應(yīng)電動勢的大小來計算流速和流量。

電磁流量計的測量范圍較寬,精度高,可用于各種液體和氣體的測量,特別是對于帶有固體顆粒和腐蝕性介質(zhì)的測量,電磁流量計也具有很好的適用性。

電磁流量計廣泛應(yīng)用于水處理、化工、食品、醫(yī)藥、石油化工等領(lǐng)域,是目前流量測量領(lǐng)域中最常用的一種流量計。

An electromagnetic flowmeter is a commonly used flow measurement instrument that is used to measure the flow of liquids or gases in pipes. It measures the flow of fluid by sensing the electromagnetic field produced by the flow of the fluid. It works on the principle of Faraday's law of electromagnetic induction. In a conductive medium, such as water or wastewater, a magnetic field is generated by two electrodes. When the conductive medium flows in the magnetic field, an induced electromotive force (EMF) is generated between the two electrodes. This induced EMF is proportional to the flow rate of the conductive medium, and this makes it possible to measure the flow rate accurately.

The operating principle of an electromagnetic flowmeter is to detect changes in the induced EMF caused by the movement of charged particles in the liquid or gas being measured, and to use the detected changes in EMF to calculate the flow velocity and flow rate. The electromagnetic flowmeter has a wide measuring range, high accuracy, and can be used to measure a variety of liquids and gases. It is particularly suitable for measuring media containing solid particles and corrosive media.

Electromagnetic flowmeters are widely used in water treatment, chemical, food, pharmaceutical, petrochemical, and other industries. They are currently the most commonly used flowmeter in the field of flow measurement.
