Thermal biogas mass flow meter adopts thermal diffusion principle, designed for biogas containing trace moisture. It directly measures mass flow without temperature/pressure compensation, with 304 probe and multi-output for digester and wastewater biogas monitoring.
Thermal diffusion principle, no pressure & temperature compensation required
Direct mass flow measurement, accurate for methane mixed biogas
304/Hastelloy anti-corrosion probe, resistant to trace water & hydrogen sulfide
Wide measuring range, ultra-low flow detection down to 0.1Nm/s
Multi-signal output: 4-20mA, pulse, RS485 Modbus RTU
Dual relay upper/lower biogas flow alarm function
IP65 transmitter, optional intrinsically safe explosion-proof version
Low maintenance, no moving parts, anti-blocking design
