Thermal Mass Flow Meter (Gas Flow, RS485 / 4–20mA, High Precision Controller)
High-precision thermal mass flow meter for accurate gas flow measurement with digital and analog outputs.
This thermal mass flow meter is designed for precise measurement and control of gas flow in industrial and laboratory applications. Using thermal dispersion technology, it directly measures mass flow without requiring temperature or pressure compensation under stable conditions.
The unit supports multiple output options including RS485, 4–20mA, and digital switching outputs, enabling seamless integration with PLCs, SCADA systems, and automation platforms. Its wide turndown ratio allows accurate measurement across a broad flow range.
Suitable for clean, dry gases, the device is commonly used in process control, gas monitoring, and flow regulation applications. With fast response time and stable repeatability, it provides reliable performance in both continuous monitoring and control environments.
