Product Description
The digital gas mass flow meter series is based on the thermal principle and calculates the mass flow rate of gases by measuring resistance changes. The product adopts independently developed MEMS flow sensor chips, which have good accuracy, excellent performance, stability and reliability in the full range. It has the characteristics of intuitive, accurate, stable, high and low temperature resistance, good linearity, and rapid response. It has two modes of battery power supply and external power supply, achieving the advantages of flexible use and cumulative flow measurement.
Application:
This item is used to monitor the mass flow rate of dry, clean, and non corrosive gases such as carbon dioxide (excluding flammable and explosive gases). It can be widely used in scientific research, fire protection, environmental monitoring, tobacco, smart agriculture, food, medicine and other industries in universities.
