Beijing Huaxu CenturyThe HXMF03 series gas mass flowmeter/controller adopts capillary thermal sensing technology and the principle of thermal temperature difference, that is, the heat exchange relationship between the fluid and the heat source in the flow, to measure and control the mass flow rate of gas. Since the thermal temperature difference is only related to the mass flow rate of the gas, its measurement value is not affected by changes in gas temperature and pressure.
The HXMF03 series of medium flow thermal mass flow products adopts a compact design, with a small and exquisite volume, and the product is sturdy and durable. The product uses a linearization correction circuit and EMI protection, which has the characteristics of safety, reliability, stable performance, low power consumption, and long service life.
In terms of data transmission, it not only has the traditional wired type, but also has powerful functions such as wireless data transmission through LAN, Internet remote data monitoring cloud platform, etc. Can effectivelySatisfy the different working conditions of various customers, widely used in many industrial and scientific research fields.
