Precise Measurement, Smart Choice: A Comprehensive Analysis of Zhongce Sensing's Pipeline-Type Intelligent Electromagnetic Flowmeter

In the fields of industrial process control and flow measurement, the accuracy and reliability of flow measurement directly impact production efficiency, cost control, and quality management. Among these, electromagnetic flowmeters stand out as the preferred solution for measuring conductive liquid flow, thanks to their exceptional advantages such as high measurement precision, minimal pressure loss, and versatility in handling various media. Today, we will delve into a detailed analysis… Zhongce Sensing Pipeline-Type Intelligent Electromagnetic Flowmeter , helping you gain a comprehensive understanding of its technical features and providing you with a professional guide for selecting key components such as electrodes, linings, and housings.

I. Working Principle: Based on Faraday's Law of Electromagnetic Induction

The Zhongce Sensing pipeline-type intelligent electromagnetic flowmeter operates based on Faraday's law of electromagnetic induction. Inside the sensor, there is a pair of measuring electrodes and a set of excitation coils. When a conductive liquid flows through a magnetic field oriented perpendicular to the direction of flow, an induced voltage proportional to the average flow velocity is generated. This voltage signal is captured by the electrodes, then amplified, filtered, and digitally processed by an intelligent converter—ultimately enabling precise calculation of both instantaneous and cumulative flow rates.

Its core advantage lies in:

The measuring tube has no obstructions inside. : Extremely low pressure loss, energy-efficient and environmentally friendly.

The measurement results are independent of fluid density, viscosity, temperature, and pressure. : Simply meet the minimum conductivity requirement.

High measurement accuracy : Accuracy can reach ±0.5%, ±0.2%, or even higher.

II. Core Component Selection: The Best Solution Tailored Specifically for You

Electromagnetic flowmeters are highly adaptable, but their long-term stability and measurement accuracy heavily depend on whether they are properly selected. Among these factors, Electrodes, linings, and casings The selection is of paramount importance, directly determining whether the flowmeter can handle the specific operating conditions.

1. Electrode Selection: The "Sensory Organ" Directly Facing the Medium

The electrode is the core component that directly contacts the fluid being measured and is responsible for signal acquisition. Its material must meet the requirements of corrosion resistance, wear resistance, and anti-fouling properties.

Recommendation Options : Be sure to select based on the chemical properties (composition, concentration, temperature) of the medium being measured. If you're uncertain, consult Zhongce Sensing's technical engineers and provide a medium sample or detailed operating condition parameters to receive the most accurate recommendation.

2. Lining Choices: The Sturdy "Liner Guardian"

The lining is applied to the inner wall of the measuring tube, serving to isolate the conductive metal tube body from corrosive media while also preventing electrode short circuits. When selecting a lining, primary considerations include the corrosivity, abrasiveness, and temperature of the medium.

Recommendation Options Follow the principle of selecting PTFE/FFKM for corrosive media, PU/ceramic for abrasive media, and cost-effective rubber for conventional media. At the same time, be sure to pay attention to the operating temperature range.

3. Shell Selection: A Reliable "External Armor"

The outer casing protects the internal excitation coil and electrical components, with its protection rating and material determined by the installation environment.

Protection Rating (IP Code) ：

IP65 : Splash-proof, suitable for most indoor industrial environments.

IP67 : Splash-proof and temporarily submersible, capable of handling splashes or brief immersion.

IP68 : Submersible type, capable of long-term underwater operation, suitable for applications such as underground wells and swimming pools.

Shell Material ：

Carbon steel + epoxy resin coating : Economical and durable, suitable for general industrial environments.

Stainless Steel (304/316) : Highly corrosion-resistant, making it suitable for applications in food, pharmaceuticals, chemicals, and other environments with hygiene or corrosive requirements.
