Research on calibration device of mobile high pressure natural gas flowmeter
As a big energy consumption country,China's demand for natural gas is increasing year by year,and long distance pipeline has become the main way of natural gas transportation.In order to en-sure the accuracy of the flow meter,according to the national verification regulations,the verification period of the flow meter shall not exceed two years,and the flow meter in the process of use often due to on-site working conditions,environmental factors and other reasons can not be sent in time,resulting in the use of the flow meter overdue,resulting in metering disputes.To solve this problem,a mobile high pressure natural gas flowmeter verification device is proposed in this paper.The verification device is placed in a special box with U-shaped structure,which can be used for on-site real flow verification in different places and under different working conditions.The experiment and results show that the mobile high pressure natural gas flowmeter verification device has stable performance under different working conditions and meets the requirements of flowmeter verification.
