Product Overview

The PFMB7202-N06-FN is a high-precision digital flow switch designed for monitoring and controlling the flow of air or nitrogen in pneumatic systems. With a clear two-colour display, flexible outputs and compact design, it offers both real-time monitoring and control functions in a single device — ideal for automation, energy-saving, and system diagnostics.

Key Features

• Two-colour digital display that improves visibility of flow conditions and alarm states.
• Wide flow rate measurement range (for the “7202” series) enabling use in larger systems.
• Integrated flow adjustment valve for easier commissioning and fine-tuning.
• Dual switch outputs plus analogue output (depending on variant) for flexibility in control and signalling.
• Compact, lightweight body (approx. 155 g) simplifies installation in confined spaces.
• Threaded ports (e.g., N06 = 3/4″) and NPT or Rc types make it compatible with common piping.
• Unit-selection function and accumulated flow/hysteresis settings for versatile use.
• Digital set-point adjustment and LED status indicators for switch outputs.

Applications

• Monitoring compressed air systems for flow verification and fault detection.
• Automation systems where flow thresholds must trigger control actions or alarms.
• Pneumatic distribution networks in factories – tracking consumption, identifying leaks or abnormal flows.
• Preventive maintenance programmes for air-supply systems, instrument air or nitrogen utilities.
• OEM integration into pneumatic control panels or custom systems requiring flow feedback.
