Insertion thermal gas mass flow meter adopts plug-in probe design, suitable for large-diameter gas pipelines. Direct mass measurement without T&P compensation, easy hot-tap installation, ideal for biogas, compressed air and industrial gas monitoring.
Plug-in structure, hot tapping installation without pipeline shutdown
Applicable pipe diameter DN25~DN2000, cover large industrial pipelines
Thermal diffusion principle, direct mass flow output, no compensation needed
Ultra-low flow detection down to 0.1Nm/s, wide turndown ratio
Hastelloy/316L anti-corrosion probe, adapt biogas & trace corrosive gas
Multi-signal output: 4-20mA, RS485 Modbus, dual relay alarms
Low pressure loss, no blockage, long service life with low upkeep
Compact probe, small space requirement for complex pipe layouts
