Influence of Calibration Period of Natural Gas Metering Device

Abstract: The information on the influence of the calibration cycle of natural gas metering devices is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Influence of natural gas metering device verification period Natural gas metering According to the requirements of JJF640-1994 'differential pressure flowmeter' verification regulations, the verification period of the orifice metering device is 1 year. Industrial natural gas metering devices are generally distributed in the field, under climate and environmental conditions. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the impact of the natural gas metering device calibration cycle. Influence of the verification period of the natural gas metering device According to the requirements of the verification regulations of JJF640-1994 'Differential Pressure Flowmeter', the verification period of the orifice metering device is 1 year. Industrial natural gas metering devices are generally distributed in the field, and the climate and environmental conditions are complex, so the stability inspection of the device is particularly important. In order to further improve the stability and accuracy of the orifice plate metering device, it is necessary to strengthen the period checking of the metering device. The main contents of the verification during the period: (1) Natural gas measurement to test the zero point range and linearity of the pressure/differential pressure transmitter; (2) Test the temperature transmitter; (3) Carry out the transmitter and flow accumulation calculation (4) Correct parameters such as temperament and pipeline. Strengthen the role of period verification: (1) Through regular verification, the changes of the flowmeter (such as transmitter drift, pressure pipe leakage, etc.) can be found in time to reduce the failure frequency of the metering device; (2) It is conducive to metering management, It is convenient for the measurement department to understand the accuracy and reliability of the flowmeter; (3) it is helpful for the user to understand the status of the natural gas metering device and strengthen the relationship between the natural gas supply and demand sides. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
