我们一直致力于流体控制和测控领域的持续创新，始于2005……
进口热式气体质量流量计是利用流体流过外热源加热的管道时产生的温度场变化来测量流体质量流量，或利用加热流体时流体温度上升某一值所需的能量与流体质量之间的关系来测量流体质量流量的一种流量仪表。无须压力、温度补偿，就能方便地检测在管道中流动的天然气、空气、氧气、氮气、氩气、煤气、烟道气等气体的质量流量。
retzThermal gas mass flowmeter is a flow instrument that measures fluid mass flow using the temperature field changes generated when a fluid flows through a pipe heated by an external heat source, or uses the relationship between the energy required for the fluid temperature to rise to a certain value when heating the fluid and the fluid mass to measure fluid mass flow. Without pressure and temperature compensation, it is convenient to detect the mass flow of natural gas, air, hydrogen, oxygen, chlorine, nitrogen, argon, ammonia, biogas, coal gas, flue gas (excluding acetylene), and other gases flowing in the pipeline.
A true mass flowmeter eliminates the need for temperature and pressure compensation for gas flow measurement, making measurement convenient and accurate. The mass flow rate or standard volume flow rate of the gas can be obtained.
Wide range ratio, capable of measuring gases with flow rates as high as 100 Nm/s and as low as 0.1 Nm/s, and can be used for gas leak detection.
Good seismic performance, long practical life, sensor without moving parts and pressure sensor components, and measurement accuracy is not affected by vibration.
Installation and maintenance are simple and convenient, and installation and maintenance can be achieved without stopping production if site conditions allow.
According to different on-site process pipelines, it can be installed horizontally, vertically, and obliquely at different angles.
Digital design, overall digital circuit measurement, accurate measurement, convenient maintenance.
Using RS-485 communication or HART communication can achieve factory automation and integration.
