Function Description

The GF4000 series measures the small gas flow rate from 0 to 500SLM based on thermodynamic principles. It can measure dry air, nitrogen and other non-corrosive gas with high precision. It contains a MEMS thermal sensor chip and a high- performance CMOS microprocessor. Combined with a unique calibration scheme , It can output real-time and accurate flow signals.
