What are the structural components of an electromagnetic flowmeter?
Electromagnetic flowmeters have consistently enjoyed strong sales in the market. Recently, many users have raised questions about these flowmeters. So now, let’s take you on a journey into the world of electromagnetic flowmeters and introduce you to their various structural components.
Electromagnetic flowmeters primarily operate on the principle of electromagnetic induction and consist mainly of a magnetic circuit system, a measuring conduit, electrodes, a housing, and other components.
1. Magnetic Circuit System: Its function is to generate a uniform DC or AC magnetic field. The DC magnetic circuit has a simple structure and is less susceptible to interference from AC magnetic fields. However, it is prone to polarization, which increases the internal resistance between the two poles and thereby affects the normal operation of the instrument. For this reason, electromagnetic flowmeters generally employ an alternating magnetic field.
2. Measurement conduit: Its function is to allow the conductive liquid being measured to flow through it. To ensure that the magnetic flux is shunted or short-circuited when magnetic field lines pass through the measurement conduit, materials such as stainless steel, fiberglass-reinforced plastic, and aluminum are typically selected.
3. Electrode: Its function is to extract the induced potential signal, which is proportional to the quantity being measured.
The above is a summary of the main components and functions of electromagnetic flowmeters. We hope this helps you gain a better understanding of these devices. If you have any other questions, feel free to call us at 0314-5932916—we’re here to assist you anytime!

Longzhida Company Successfully Hosted the Victory Parade Commemorating the War of Resistance.
Today is a day that every Chinese person should solemnly remember—the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War.
On July 2, Chengde Longzhida Company held a meeting with the Sino-German Institute. After thorough discussions between the two sides, Mr. Bai, General Manager of Longzhida Company, and the faculty team from the Sino-German Institute reached a consensus: Longzhida Company officially entrusted the Sino-German Institute to carry out the design and R&D work for a new type of ultrasonic water meter.
On May 30, Longzhida Company successfully held an exceptionally meaningful event titled “Welcoming the Eighth ‘National Science and Technology Workers’ Day’: Promoting the Spirit of Scientists.”
