Product Introduction
The GTMM-26 Micro Electromagnetic Flow Meter is a high-performance, ultra-compact smart sensor designed based on Faraday’s Law of Electromagnetic Induction to precisely measure even the most minute liquid flows. Specifically engineered for ultra-small pipe diameters (DN3 to DN32), it provides exceptional stability and reliability in low-flow environments by converting fluid velocity into electrical signals. With its superior repeatability and robust construction, it delivers dependable real-time flow data even in the most demanding industrial processes.
Product Features
- Ultra-Precise Low-Flow Measurement: Capable of measuring extremely fine flows starting from a minimum of 1 L/h, with a wide dynamic range (0.001 to 10 m/s) ideal for high-precision process control.
- Intuitive LCD Display: Features a built-in digital LCD that allows users to clearly monitor instantaneous flow, totalized flow, velocity, and alarm messages at a glance.
- Versatile Output & Communication: Supports 4–20mA analog output, RS485 (MODBUS RTU), pulse output, and HART protocol, ensuring excellent compatibility with various control systems.
- Superior Durability & Material Options: Offers PEEK or ceramic lining options combined with electrode materials like 316L, Hastelloy C, and Titanium to ensure long-term durability against corrosive fluids.
- High Accuracy & Repeatability: Provides high-accuracy classes (0.2%, 0.3%, or 0.5%) with repeatability maintained within 1/3 of the accuracy class for maximum system reliability.
Applications
- Semiconductor & High-Tech: Optimized for semiconductor manufacturing processes and chemical injection systems requiring precise micro-flow control.
- Pharmaceutical & Food/Beverage: Widely used in pharmaceutical production, breweries, and food processing lines where hygiene and precise ingredient blending are critical.
- Environment & Water Treatment: Suitable for urban water system management and municipal wastewater treatment facilities requiring accurate water resource management.
- Chemical & Petrochemical: Provides a reliable solution for monitoring fluid transfer in corrosive or harsh chemical processing environments.
