Description of SUTO S451

The S451 Compressed Air Flow Meter is a reliable and highly accurate thermal mass flow meter designed specifically for use in harsh operating conditions and explosive environments. The S451’s advanced built-in sensor makes it ideal for monitoring compressed air and gas flow in a wide range of industrial applications, 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.
  • Vacuum measurement: Built-in absolute pressure sensor, specifically designed for vacuum applications.

Specifications:

  • Medium: Air, N₂, O₂, CO₂, and non-corrosive gases.
  • Temperature: -30 to +140°C (Non-Ex), -30 to +90°C (Ex)
  • Pressure: 0 to 5.0 MPa (Non-Ex), 0 to 1.6 MPa (Ex)
  • Protection Class: IP67 (standard), IP65 (Ex option)

The S451 is designed to perform in demanding environments, making it ideal for a variety of industrial applications:

  • Chemical and Petrochemical Industries: Monitors gas flow, ensures safety in explosive atmospheres, and optimizes compressed air systems.
  • Oil and Gas: Measures gas flow in extreme conditions, maintains safety in hazardous locations, and monitors equipment efficiency.
  • Energy and Utilities: Manages compressed air in power plants, ensures pneumatic system reliability, and monitors emissions.
  • Food and Beverage: Maintains gas purity and quality, operates efficiently under all weather conditions, and reduces operational costs.
  • Pharmaceuticals: Monitors gases in manufacturing under strict safety conditions, ensures compliance, and enhances production efficiency.
  • Automotive: Manages pneumatic tools and machinery in robust environments, ensures efficient assembly lines, and reduces waste.
  • Metal and Mining: Measures gas flow in extreme conditions, ensures safety in explosive environments, and optimizes compressed air use.
