مقياس تدفق كتلة الغاز الحراري

مقياس تدفق كتلة الغاز الحراري

  • No temperature and pressure compensation is required for gas flow measurement, and the measurement is convenient and accurate. The mass flow rate or standard volume flow rate of the gas can be obtained.
  • Wide range ratio, it can measure gas with flow rates as high as 100Nm/s and as low as 0.1Nm/s, and can be used for gas leak detection.
  • Good vibration resistance and long service life. The sensor has no moving parts and pressure sensing parts, and is not affected by vibration on measurement accuracy.
  • Easy to install and maintain. If the site conditions permit, installation and maintenance can be achieved without stopping production. (Customization required)
  • Digital design. Overall digital circuit measurement, accurate measurement and convenient maintenance.
  • Adopting RS-485 communication or HART communication can realize factory automation and integration.

نظرة عامة على المنتج:

Thermal gas mass flow meter is a flow meter designed based on the principle of heat diffusion or heat conduction, which uses the constant temperature difference method to accurately measure the gas. It has the advantages of small size, high degree of digitization, easy installation, and accurate measurement. It is mainly composed of two reference-level thermal resistors (RTDs), one is the velocity sensor RH (heater), and the other is the temperature sensor RMG that measures the temperature change of the gas.

طلب:

Industrial production process: In the fields of chemical industry, petrochemical industry, metallurgy, etc., it is used to measure the flow of reactants, catalysts, raw materials and other substances to ensure the stability and efficiency of the production process.

Environmental protection monitoring: used to monitor the flow of atmospheric, flue gas and other gas emissions, and provide data support for environmental governance.

Medical and pharmaceutical applications: In medical equipment such as ventilators and hyperbaric oxygen chambers, it is used to accurately control the flow of oxygen and air to ensure patient safety and treatment effectiveness.
