| Detailed Product Description： | Overview:
Thermal gas mass flow meter is a gas flow measurement in the new instrument, different from the other gas flow pressure and temperature correction does not require a direct measurement of gas mass flow, a sensor can be range from low to high range. It is suitable for a fixed proportion of single gas and multi-component gas measurement. It is based on the principle of heat absorption rate of the fluid mass flow directly related. Moving gas molecules absorb impact when the heat resistance of the heat away, the greater the flow rate, thermal contact resistance of the molecules the more heat absorbed more heat absorption and a number of molecules of gas, thermal properties and flow characteristics. Features: * Do not need temperature and pressure compensation; ? A flow meter can simultaneously take into account the small flow and large flow measurement, especially for large diameter measurement. * Construction of small amount, the use of plug-in structure, only need to open a pipe M20 ×. * With a ball valve, calibration and easy maintenance. * Smart Digital Flow Totalizer support. * Base meter with alarm for local display and control. Technical performance: For diameter: Ф15-Ф3000mm Medium: gas compatible with stainless steel Accuracy: ± ± 2% FS Repeatability: ±% FS Medium temperature: -10-100 ℃ Media pressure: <3MPa Power: 24VDC three-wire 220V (base-type) Output: 4-20mA (RS232 RS485 Relay output) Process connection: M20 × Straight pipe Requirements: upstream 10D, 5D downstream Phone: |
