The MF4000 Series is a advanced gas mass flow meter designed for low-flow gas measurement in pipelines with diameters of 3 mm to 8 mm. It utilizes Micro-Electro-Mechanical Systems (MEMS) thermal sensor technology to provide accurate and reliable mass flow measurements without requiring temperature or pressure compensation. Suitable for a wide range of industrial and medical applications, it offers high precision, excellent repeatability, and flexible output options.
The key specifications for the MF4000 series (with models MF4003 for 3mm diameter and MF4008 for 8mm diameter) are summarized in the table below:

The MF4000 series stands out due to several important features:
High Precision & Wide Rangeability: Offers an accuracy of ±(1.5+0.2FS)% and a impressive 100:1 turndown ratio, allowing for reliable measurement across a broad flow range.
MEMS Sensor Technology: The core MEMS thermal sensor provides fast response times (as low as 10 ms), high stability, and measures mass flow directly, eliminating the need for external temperature or pressure compensation.
Flexible Output & Communication: Provides multiple output options including analog voltage (0.5~4.5 VDC), RS232, and RS485, facilitating easy integration into various control and monitoring systems.
User-Friendly Design: Features an LED display for showing instantaneous and cumulative flow, and allows for on-site parameter configuration via buttons.
Compact & Versatile Installation: Its compact design and multiple available connection types (threaded or quick-connect) make it easy to install in diverse applications and space-constrained environments.
Low Power Consumption: With a typical requirement of 50 mA, it is suitable for applications where power efficiency is important, including potentially battery-operated systems.
The MF4000 gas mass flow meter is versatile and is commonly used in:
Medical & Healthcare Equipment: Anesthesia machines, ventilators, respiratory devices, hospital oxygen supply systems, and patient monitoring.
Industrial Process Control & Automation: Monitoring and controlling gas flow (e.g., compressed air, O₂, N₂, H₂, He) in various manufacturing and processing applications.
Environmental Monitoring & Analysis: Air samplers, gas analyzers, and other equipment used for environmental detection and emission monitoring.
Laboratory & Analytical Instruments: Particle counters, spectrometers, and other precision instruments requiring accurate gas flow measurement.
General Purpose Low-Flow Gas Measurement: Any application involving low flow rates of clean, dry gases in small diameter pipes where reliable data is critical.
