DFS1 Series Smart Digital Flow Sensor (Flow Meter)

Model: Digital Air Flow Meter 1/2" 10-1000 LT/MIN 1xPNP + 1x4-20mA

The DFS1 Series is a professional digital flow meter designed to monitor air consumption in real-time, detect leaks, and maximize energy efficiency in your pneumatic systems. With its dual-line digital display, compact design, and Industry 4.0 compatible output options, it is an essential component for your automation projects.

Energy Saving Tip: With the DFS1 flow sensor, you can detect air consumption (leaks) even when your system is idle, potentially reducing your operating costs by up to 20%.

Key Features

[cite_start]
Wide Measurement Range: Flexible selection with 500 L/min, 1000 L/min, and 2000 L/min models[cite: 18, 20, 21].
[cite_start]
Dual Screen Technology: Simultaneous display of current flow value and threshold setting value[cite: 35].
[cite_start]
Multi-Output Support: NPN/PNP switching outputs plus 4-20mA Analog or 1-5V Voltage output[cite: 32, 145].
Smart Measurement Modes: Hysteresis, Window Comparator, and Accumulated (Total) Flow tracking.
[cite_start]
Easy Installation: Rotatable screen and integrated mounting brackets[cite: 62, 73].
