Compressed Air Thermal Mass Flow Meter SRK-DL for Leak Detection

Product Summary

The Silver Automation SRK-DL thermal mass flow meter is optimized for compressed air flow measurement. With a wide flow range from 2 sccm to 30 SLM and ±1% F.S accuracy, it enables precise monitoring of air consumption, leak detection, and energy optimization. Its robust stainless steel construction withstands industrial environments, while RS232/485 communication facilitates integration with DCS/PLC systems.

Key Selling Points

• Wide Turndown Ratio: Measures flow from 2 sccm to 30 SLM, covering low night flow to high production flow. Source: product parameters.
• Accurate Leak Detection: Demonstrated capability to detect leaks as low as 2 ml/min, helping reduce energy waste. Source: case study (2 sccm low flow air measurement).
• Multiple Output Options: Provides 0-5V, 4-20mA, or 1-5V signals for easy connection to monitoring systems. Source: product parameters.
• Industrial Communication: RS232/485 with MODBUS enables data logging and remote monitoring. Source: product parameters.
• Reliable in Harsh Conditions: Stainless steel body resists moisture, oil, and dust common in compressed air systems. Source: material field and working condition description (contaminants).
