What is the application solution of flow sensor MF5700 in nitrogen control cabinet? I believe many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Nitrogen holder is widely used in semiconductor, solar energy, precious metal, electronics, LED and other industries, mainly for the storage of oxidizable goods. The working principle of the nitrogen tank is to replace the air in the cabinet through the filling of nitrogen, so as to reduce the oxygen content in the cabinet and achieve the purpose of anti-oxidation.

The existing nitrogen tank is provided with a gas charging port on the cabinet body, which is then connected to the nitrogen cylinder or the inert gas cylinder through a pipeline. In order to ensure that the oxygen concentration in the cabinet is maintained at a certain value, the conventional method is to repeatedly charge nitrogen with a small flow rate. However, if we only rely on measuring the pressure and / or flow rate of nitrogen in the cabinet, we can not accurately control the oxygen content in the cabinet, improve the utilization rate of nitrogen according to the difference of storage, and affect the storage quality of storage.

In order to adjust the nitrogen charge according to the gas content in the cabinet, improve the utilization rate of nitrogen or inert gas, and save the use cost. The Industrial and Mining Network recommends the Siargo MF5700 series of portable gas mass Flowmeters in the United States to monitor the flow of gas filled with nitrogen. MF5700 series portable gas mass Flowmeter is a kind of measurement instrument with wide application range, low power consumption, portable, with display and network based on the MEMS flow sensor chip independently developed by our company. The instrument is suitable for the monitoring and measurement of clinical oxygen supply in hospital (medical oxygen meter) and various industrial and commercial applications.

American Siargo MF5700 series portable gas mass Flowmeter features:

1. The sensor chip adopts thermal mass flow measurement without temperature and pressure compensation, which ensures the high precision measurement of the Flowmeter.

two。 High sensitivity, can start to measure the very small initial flow.

3. Multi-sensor integration is realized on a single chip, so that the range ratio can reach 50:1 or higher.

4. Full range high stability, high precision and excellent repeatability

5. Support the measurement of a variety of gases, allowing customers to calibrate some special gases on the spot

6. Quick response

7. The output mode is flexible, providing LC D on-site display, and also providing R S485 communication interface for the upper computer to query and output data.

8. Parameters can be configured by keystrokes

9. It has the function of alarm and indication of overrange.

10. Portable design, battery power supply and external power supply can be switched at will

11. NPT connection mode, easy to install and use, and other interfaces can be customized according to customer requirements.

After reading the above, have you mastered the application solution of flow sensor MF5700 in nitrogen control cabinet? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
