RS485 4-20mA CO2 Thermal Mass Flowmeter – DN50 Compressed Air & Biogas Measurement
High-precision thermal mass flow technology ensures ±1% accuracy for real-time monitoring of CO2, compressed air, and biogas flows. Rugged stainless steel sensor with PTFE lining resists corrosion in harsh environments like sewage treatment plants. Seamless RS485/4-20mA output integrates with SCADA or PLC systems for industrial automation. DN50 flange design enables easy installation in pipelines without flow disruption. Calibrated for multiple gases (CO2, methane, air) with wide 0.3-30m/s velocity range. IP65-rated housing withstands dust and moisture, ideal for outdoor/plant use. Low power consumption (12-24VDC) with zero moving parts ensures maintenance-free operation. Includes NIST-traceable certificate for compliance with ISO/IEC standards.
Key Applications:
- Compressed air leak detection in manufacturing - Biogas flow monitoring in wastewater facilities - CO2 emission tracking for environmental reporting - HVAC system balancing in commercial buildings
