Small thermal gas mass flowmeter
A small thermal gas mass flowmeter uses highly sensitive sensors to directly measure flow inside the pipeline, without laminar flow or pressure loss, and has a fast response speed and small drift. Solved the inherent defects of traditional thermal flow meters; The long-term heating mode generates thermal drift and slow reaction speed. For applications involving corrosion and crystallization, stainless steel sensor specifications can also be used.

The small thermal gas mass flowmeter is designed for analog and digital compatibility, and can be set and displayed for instantaneous flow through analog secondary instruments and PLC. It can also communicate directly with a computer through a digital interface. It has the characteristics of being applicable to both analog and digital control systems. This product adopts a multi gas and multi range design to facilitate users’ existing configuration of flow meters.

Applicable occasions: vacuum, coating, solar energy, semiconductor, petroleum and petrochemical, coal metallurgy, gas production and distribution, environmental protection, various analytical instruments.
