Diameter: DN25 (1"), internal thread G1"
Range (air, 20°C/1 atm): 2–100 m³/h (standard)
Accuracy: ±(2.0% reading + 0.5% FS)
Repeatability: ≤±0.5%FS
Range ratio: 50:1 (wide range)
Response time: ≤2 s
2. Electrical and Interfaces
Power supply: 24 VDC ±10%
Output: RS485 (Modbus-RTU) + 4-20mA (flow rate)
Display: LED, 4-digit instantaneous flow + 8-digit cumulative quantity
Power consumption: ≤2 W

III. Main Applications
1. Industrial gas measurement (core)
Compressed air: Monitoring of workshop / equipment gas usage, energy cost allocation, energy-saving audit
Nitrogen / oxygen / argon: Chemicals, electronics, welding, heat treatment gas flow control
Carbon dioxide: Food packaging, greenhouses, welding shielding gas
2. Environmental and energy
Waste gas / exhaust gas: Monitoring of low-concentration clean emissions gases
Gas / biogas: Domestic / industrial gas quality flow measurement (dry and free of impurities)
Energy management: Factory gas energy consumption monitoring, cost accounting
3. Manufacturing support
Electronics / semiconductor: Precise ratio and flow control of high-purity gases (N2/O2/Ar)
Food /: Monitoring of sterile gas, protection gas flow
Welding / cutting: Stable control of protection gas (Ar/CO2)
4. Laboratory and general equipment
Experimental gas: Small flow, high precision gas ratio and measurement
Combustion control: Quality flow closed-loop control of gas / auxiliary gas
IV. Model Comparison (same series)
MF2025BE-AB-A: DN25, 2–100 m³/h, RS485 + 4-20mA, with display (this model)
MF2032: DN32, 5–160 m³/h
MF2050: DN50, 10–400 m³/h
V. Installation and Notes
Medium must be dry, clean, free of oil, and without condensate water
Avoid strong vibration, strong electromagnetic interference (away from frequency converter)
When installed horizontally, the display faces upwards; when installed vertically, the flow direction is from bottom to top
