Mass flow meters/controllers need to be calibrated regularly, do you know

Working measuring instruments included in the 'Compulsory Verification Catalog of Measuring Instruments' for trade settlement, safety protection, medical hygiene, environmental monitoring, etc. Mandatory third-party calibration is required on a regular basis. In order to ensure the consistency of the production process, regular calibration of the flowmeter can maintain the quality and accuracy of the equipment. Update the firmware to help you update the program version. Azimuth detects the usage status of the flowmeter and eliminates hidden troubles. the“It is used in the four fields of trade settlement, security protection, medical and health care, and environmental monitoring, and must be regularly calibrated by a third party”If the flowmeter/controller you use is used in the four fields of trade settlement, safety protection, medical and health, and environmental monitoring, it needs to be regularly calibrated by a professional metrology and verification department, and a third party will issue a verification certificate or Calibration certificate. The thermal gas flowmeter verification regulations JJG1132-2017 document stipulates that the flowmeter verification cycle generally does not exceed 2 years. For fields other than the above four types, customers can determine the calibration cycle that meets their own needs according to the working conditions and gases used by the flowmeter. If customers want to maintain the quality and accuracy of measurement and control products, Qixing Flowmeter can also provide you with calibration services. Qixing flowmeter calibration service“four steps”1. Assessment and inspection. Before recalibration, our service engineers will conduct a comprehensive evaluation and inspection of the equipment. The inspection items include: analog signal, parameter setting, sensor status, electrical interface, interface thread, and even equipment appearance problems. 2. Parameter adjustment. After careful evaluation, we will make necessary adjustments to the parameter settings of the equipment to optimize the working performance. 3. Serial calibration. Afterwards, the engineer will connect the equipment in series with the standard table, and use the standard table to calibrate the equipment. 4. After the calibration is completed, a calibration certificate will be generated. Annual calibration which contains both before and after calibration data. On the calibration certificate we list certain parameters and conditions related to the calibration: Process gas: pre-selected gas from the gas menu. This can be changed via the front panel or during recalibration. Calibration gas: The gas used to calibrate the device. We generally use nitrogen unless the customer has a specific request for a calibration gas. Range: the full range of the device. Since our products can customize the range, this range may be different from the body range in the main model. Gas temperature: the gas temperature when the equipment is calibrated. Ambient Humidity: The humidity when the device is calibrated. Helium mass spectrometer leak detection: Exposed leak rate during equipment calibration. Response time: the response speed during calibration. Working pressure difference: the working pressure difference when the equipment is calibrated.
