Insertion thermal gas mass flow meter uses thermal diffusion principle, with plug-in stainless probe for DN25 above pipelines. Directly measures gas mass without pressure-temperature compensation, equipped local LCD, supporting pulse,4-20mA, RS485 signals, easy mounting without pipe cutting.
Plug-in structure, no pipeline cutting, convenient installation and disassembly
Suitable for gas pipelines DN25~DN2000
SS316L corrosion-resistant measuring probe
Direct mass flow measurement, no T&P compensation needed
Ultra-low starting flow, tiny pressure loss
Local LCD shows instantaneous and cumulative flow
Multiple outputs: 4-20mA, pulse, RS485, relay alarm
Low cost compared with full pipe type for large pipes
Wide adaptability for air, biogas, nitrogen, natural gas
IP65 protection, optional intrinsic safety explosion-proof
