Beijing Huaxu CenturyThe HXMF05 series gas mass flowmeter/controller adopts digital technology, which improves accuracy and digitalization compared to analog technology. It adopts capillary thermal sensing technology and thermal temperature difference principle 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 HXMF05 series small flow thermal mass flow products adopt a compact design, with a small and exquisite volume, and are 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 traditional wired methods, but also wireless transmission of data through local area networks and interconnectionPowerful features such as remote data monitoring cloud platform.
