High Protection Performance

a) The sensor protective housing adopts high-performance composite materials instead of traditional metal casings, surpassing metal casings in corrosion resistance, humidity and heat resistance, and sealing. It is better suited for harsh environments. The new material casing has an internal electromagnetic shielding coating, providing the same anti-electromagnetic interference capability as metal casings.

b) Using patented technology, the sensor excitation coil is vacuum-sealed with epoxy resin to form a uniform, dense, and robust insulating layer, eliminating short circuits, leakage, and other electrical faults. It effectively isolates the coil from external environmental influences such as humidity and temperature shocks, making it less prone to corrosion and damage. This ensures long-term stable performance of the coil in harsh environments, guarantees precise and stable signal output, and effectively extends the lifespan of the instrument.

2. Excitation component vacuum sealing technology:

Epoxy resin vacuum sealing is an advanced packaging technology that involves injecting liquid epoxy resin into the excitation components under a vacuum environment, and then curing it at high temperatures. The full-bore (DN15-DN2400) SF series electromagnetic flow meters use this technology to treat sensor excitation components. Despite the high manufacturing cost and complex process, it can significantly optimize the performance of the instrument and solve the pain points of on-site use:

a) Improving electrical insulation performance: The vacuum encapsulation process ensures that the epoxy resin fully penetrates into every gap of the coil, forming a uniform and dense insulation layer. It greatly improves the electrical insulation performance of the coil, effectively preventing short circuits, leakage, and other electrical faults.

b) Enhancing Mechanical Strength: Through the vacuum infusion process, epoxy resin and the excitation components are tightly bonded to form a robust unit. This structure not only improves the mechanical strength of the coil but also enhances the sensor's resistance to pipeline vibrations and impacts, stabilizes the output flow signal, and extends the lifespan of the sensor.

c) Enhancing sealing and environmental resistance: Epoxy resin can better fill the tiny gaps and cracks of the excitation components in a vacuum state, forming a dense encapsulation layer. This improves the sealing performance of the excitation coils, effectively isolating the invasion of gases, moisture, and other corrosive substances, such as underwater or in corrosive environments. It ensures that the core components maintain stable performance in harsh environments, making them less susceptible to corrosion and damage.

d) Improved temperature resistance: High-quality epoxy resin maintains good stability at high temperatures, and vacuum encapsulation further enhances the sensor's temperature resistance, enabling it to work in more severe environmental conditions.

e) Improving Thermal Management: The use of high-quality epoxy resin modified with thermally conductive fillers for vacuum impregnation of the excitation coil can form a dense insulation layer. This helps improve the heat generated by the excitation coil, reduce linear drift caused by fluid or ambient temperature changes, and optimize instrument output signals.

f) Enhancing product reliability: Since vacuum sealing technology offers better protection and isolation, flow meters using this technology generally have higher reliability and a longer service life.

3. Signal shielding system:

The instrument uses double Signal shielding system: The instrument uses doubles that meet the GJ The instrument uses double-layer shielded cables that meet the GJB774A quality requirements, with a silver-plated shielding layer density of ≥99%, ensuring that millivolt-level flow signal output is free from interference. Coupled with a special electrode sealing and shielding process, the sensor possesses long-term stable zero points, excellent linearity, and strong anti-interference capabilities. In practical applications, there is no need to use methods for adjusting the zero point for linear compensation, simplifying the operation process and enhancing measurement accuracy and reliability.

4. Composite Material Assembly Shell:

 

The SF series flowmeters (DN15-DN300 size) utilize high-performance fiberglass composite material shells, which offer the following significant advantages over traditional metal casings:

 

a) Magnetic System Protection: Traditional metal casings undergo high-temperature heating and rapid cooling during welding, a thermal cycle that can change the microstructure of soft magnetic materials, leading to a decrease in their magnetic properties such as reduced permeability and increased loss factors. The design of the new material assembly shell avoids the impact of thermal effects on the magnetic system's performance.

b) Good Maintainability: The sensor casing uses lightweight and high-strength materials, characterized by high strength and low density, making it both light and robust. Compared to metal casings, the modular design of the sensor casing is easy to maintain and repair, addressing the pain point of non-repairable metal casings. Additionally, this design not only facilitates the environmental recycling of materials but also simplifies the installation and maintenance process, enhancing the product's lifespan and reliability.

c) Superior Interference Resistance: The new material casing is coated with a graphene electromagnetic shielding layer internally. Graphene's unique two-dimensional structure and electronic properties enable it to efficiently block electromagnetic interference. Compared to traditional metal casings, this design not only maintains excellent interference resistance but also significantly improves the casing's lightweight and durability, providing more comprehensive protection for the sensor.
