Product Introduction
The GTMM-26-RR micro electromagnetic flowmeter is an ultra-compact smart sensor designed to precisely measure even extremely fine flow rates based on Faraday's law of electromagnetic induction. It detects the velocity of conductive liquids flowing inside the pipe and converts it into an electrical signal. Specifically engineered for ultra-small diameters (DN3 to DN32), it provides excellent stability even in low-flow environments. In particular, based on its high repeatability and durability, it delivers reliable real-time flow data even in harsh industrial processes.
3-in-1 Integrated Sensing (Flow + Temperature + Pressure) There is no longer a need to install separate temperature or pressure gauges. With just a single GTMM-26, you can simultaneously monitor flow rate, medium temperature, and pipe pressure in real time, reducing equipment costs and increasing efficiency.
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.
- Smart Bluetooth App Control Is it installed in a location with difficult on-site access? Configure parameters and check data wirelessly through a smartphone app. This dramatically improves operator safety and convenience.
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.
