Thermal gas mass flow meter diameter 15-3000mm

Thermal gas mass flow meter thermal mass flow meter gas mass flow meter is a gas meter in the new instruments, different from other gas flow, the need for pressure and temperature correction, direct mass flow measurement of gases. A sensor can do range from low to high range. He fit a fixed percentage of single gas measuring and multi-component gas. Principle is based on the speed of the fluid absorbs heat directly related to the mass flow. When the strike movement of gas molecules absorb heat away heat resistance, the greater the flow, the more contact heat resistance of the molecule to absorb more heat, heat absorption and a certain number of molecules of gas, thermal properties and flow characteristics. Features requiring temperature, pressure compensation. A flow meter capable of taking into account the small and large flow measurement, especially for large diameter measurement. Minimal amount of construction, the use of plug-in architecture, you only need to open holes in the pipe of a Φ20. With ball, calibration and maintenance. Intelligent digital flow totalizer deals. Base instrument can control local display and with alarm. User field calibration.
