S451 Thermal Mass Flow Meter for Heavy Duty and Ex Applications (Insertion)

The S451 Compressed Air Flow Meter is a robust and highly accurate thermal mass flow meter designed specifically for heavy-duty applications and hazardous environments. With its advanced insertion-type sensor, the S451 is perfect for monitoring compressed air and gas flow in a wide range of industrial settings, including those requiring explosion-proof equipment.

Key Features:

• Durable Design: IP67-rated with stainless steel or nickel-plated components for corrosion resistance.
• High Accuracy: Measures mass flow, standard flow, consumption, pressure, and temperature.
• Data Logging: Built-in data logger with wireless access via the S4C-FS app for Android and iOS.
• Easy Installation: Insertion sensor installable under pressure through a ball valve; rotatable sensor head for display visibility.
• Comprehensive Outputs: Supports Modbus/RTU, Modbus/TCP, 4-20 mA analog outputs, and pulse/alarm outputs.
• Explosion Proof: Certified for ATEX, IECEx, and other safety standards.
