The gas mass flow controller mainly adopts the principle that the temperature change corresponds to the mass flow

The gas mass flow controller mainly adopts the principle that the temperature change corresponds to the mass flow, and can measure and control the flow of different gases. Therefore, the gas mass flow controller is widely used in the industry. As a relatively precise instrument, If we want the instrument to have a relatively long service life, it is inseparable from our maintenance during use, and we must also make good records. Then let's talk about the daily maintenance of the gas mass flow controller. 1. After the gas mass flow controller has been used for a period of time, it is necessary to regularly disassemble the gas mass flow controller to sort out the internal debris, and check whether there are damaged parts; 2. Check the pipeline rigidity of the gas mass flow controller Whether it is a lack of state, if it is, it is recommended to fix the pipeline with a bracket to avoid oscillation during operation; 3. Don’t forget to clean the inside and outside of the gas mass flow controller to avoid damage to the sealing surface; 4. Pay attention to the detection of mass flow Concentration measurement range of the controller: All kinds of mass flow controllers have their fixed detection range. Only when the measurement is completed within its measurement range can the mass flow controller be accurately measured. 5. Pay attention to regular calibration and testing: gas mass flow controllers, like other analytical and testing instruments, are measured by relative comparison methods. Therefore, zero calibration of the gas mass flow controller at any time and frequent calibration of the instrument are the only tasks to ensure accurate measurement of the instrument. To sum up, when we use gas mass flow controllers, we need to maintain them as carefully as other instruments, and make records during use, so that we can find out the cause in time if an instrument fails. . And we should pay attention, once the instrument breaks down, we try to find a professional gas mass flow controller manufacturer for maintenance. Of course, some gas mass flow controller manufacturers with good service attitude will regularly overhaul the instrument to reduce losses .
