达州High-precision electromagnetic flowmeter

Product Description

I. Product Introduction

The export-oriented electromagnetic flowmeter is an electromagnetic flow instrument based on Faraday's law of electromagnetic induction, specifically designed to meet the stringent regulations, extreme operating conditions, and diverse media requirements of overseas markets. The product offers a wide range of structural configurations, including split, integrated, insertion, hygienic, and high-pressure designs, with nominal diameters ranging from DN8 to DN300. It delivers a linear signal proportional to the average fluid velocity, enabling precise measurement of all conductive liquids with conductivity ≥ 0.5 μS/cm², as well as uniform liquid-solid two-phase flows. The entire device complies with standards such as CE, MID, ISO 9001, and ISO 14001, making it suitable for commercial trade applications.

3. Product Features
1. Ultimate Compatibility
• Flange standards: ANSI 150/300, DIN PN10/16, JIS 10K/20K, EN1092-1, AS2129, and more
• Electrode/liner materials: Hastelloy C-276, Ti, Ta, Pt-Ir, tungsten carbide, PFA, ceramics—resistant to strong acids, strong bases, seawater, and oil-sand slurries;
• Communication Protocol: Features a built-in multi-language menu, adaptive to 50/60 Hz power grids, and supports seamless integration with mainstream DCS/SCADA systems worldwide.
2. Zero pressure loss, zero blockage
Fully open-flow design with no moving or obstructive components, resulting in pressure loss of less than 1 kPa—leading to energy savings and reduced consumption. Ideal for handling highly abrasive media such as fibrous materials and mineral slurries.
3. Broadband Excitation & Intelligent Diagnosis
Dual-frequency rectangular wave excitation technology offers zero-point stability and is unaffected by fluctuations in conductivity, media buildup, or the presence of bubbles. It also features over 20 advanced self-diagnostic functions, including detection of empty pipes, electrode contamination, excitation coil short circuits, and ground faults.
4. Long lifespan, low maintenance
Whole machine requires no daily calibration; modular design.
5. Export-Quality Assurance
• Full Lifecycle Traceability: Laser Marking + Digital Twin Archive;
• Undergoes -40°C ↔ +80°C cyclic damp heat, 5 g vibration, 10 kV surge, and EMC burst pulse testing before leaving the factory;
• Packaging complies with the ISPM-15 standard for export wooden crates, and accompanying documents meet the customs and metrology registration requirements of the destination country.
4. Product Application Scenarios
