What are the applicable liquids for electromagnetic flow meters?

Case introduction

1. Working principle of electromagnetic flowmeter

Electromagnetic flowmeter measures liquid flow based on the principle of electromagnetic induction. Its basic structure consists of two parts: a measuring tube and a signal converter. When a conductor (liquid) flows through the measuring tube, an electromagnetic field is generated. The potential difference on the electrode pair is the induced potential. The induced potential is proportional to the liquid flow rate, and is converted into a standard signal output through a signal converter. The advantages of electromagnetic flowmeter for measuring liquid flow are large measurement range, high precision and good reliability, so it is widely used in the field of industrial automation.

2. Scope of application of electromagnetic flowmeter

Electromagnetic flowmeter can measure various conductive liquids, including applications in chemical, pharmaceutical, petroleum, fertilizer, papermaking, metallurgy, food and other industries. Wide range of acid, alkali, salt solution, sewage, clean water and other media. For non-conductive liquids, such as emulsions, paints, vegetable oils, petroleum, etc., it is necessary to add sensing electrodes to improve the measurement effect.

3. How to choose a suitable electromagnetic flowmeter

Selecting a suitable electromagnetic flowmeter requires consideration of many factors, such as application scenarios, measurement range, accuracy requirements, electromagnetic compatibility, etc. When selecting, a comprehensive evaluation should be conducted based on the liquid's conductivity, temperature, pressure, flow rate and other parameters, and merchant products that can provide corresponding specifications and technical support should be selected.

In short, the electromagnetic flowmeter is a widely applicable and high-precision flow meter that can measure the flow of various liquids, including non-conductive liquids. When choosing, you should choose suitable products and configure them reasonably according to the actual application scenarios and parameters.
