ATO Digital Gas Flow Meter, designed for accurate instant flow testing and volume accumulation, the ATO MF5700 Series Digital Gas Flow Meter covers flow ranges from 0-20 L/min up to 0-250 L/min (DN6 to DN12). Ideal for clean, dry gases such as compressed air, nitrogen, oxygen, argon, and carbon dioxide, this meter operates at working pressures up to 0.8 MPa. It features an intuitive LCD screen displaying flow rates in real-time, low pressure loss, and an ultra-low power design running on 4 AA batteries or a 5-24V DC adapter. Equipped with a versatile Type-C USB port for power and RS485 communication, it offers a compact, cost-effective, and user-friendly solution for industrial and laboratory gas monitoring.
