Gas Quality Flow Controllers play a crucial role in various measurement and analysis applications such as coating, semiconductor, petrochemical, coal metallurgy, and gas production and distribution. The main features of the Froome Large Range Gas Quality Flow Controller/Gas Quality Flow Meter are as follows:
1. Heat principle, rapid response, high accuracy.
2. Tubular分流 design, less prone to clogging.
3. Suitable for various low and high-pressure pipelines.
4. Short preheating time, minimal deviation, and high reliability.
5. Digital easy input/output, can be controlled or displayed with flow computers.
6. The Mass Flow Controller is composed of components such as a mass flow sensor, laminar flow divider, flow control valve, and amplifying control circuit. It is manufactured by utilizing the heat conduction distribution effect, where the temperature distribution on the capillary wall is changed through the heat transfer of the flowing fluid.
7. Utilizing the principle of capillary heat transfer temperature difference calorimetry to measure the mass flow rate of gases, unaffected by temperature and pressure. The sensor's flow signal is amplified, then compared to a set voltage, and the resulting difference is used to drive the control of the regulating valve, implementing closed-loop control to match the flow through the channel to the set flow rate.
