Abstract

The invention discloses a natural gas flowmeter calibration device and a natural gas flowmeter calibration method, and belongs to the technical field of flowmeter calibration. According to the naturalgas flowmeter calibration device and the natural gas flowmeter calibration method of the invention, a primary standard unit is used for calibrating a first sonic nozzle unit based on a first straight-row calibration module; a first transmission turbine unit is calibrated by using a second sonic nozzle unit based on a second straight-row calibration module; and a to-be-detected unit is calibratedby using a second transmission turbine unit based on a loop calibration module. Pressurizing devices are arranged in the first straight-row calibration module, the second straight-row calibration module and the loop calibration module respectively, the pressure of gas in the calibration device can be adjusted to the pressure required by a user through adjusting the pressurizing devices, and the calibration range of the calibration device is greatly increased.

Description

technical field [0001] The invention relates to the technical field of flowmeter calibration, in particular to a natural gas flowmeter calibration device and method. Background technique [0002] According to national calibration regulations, all natural gas flow meters for custody transfer need to be sent to a natural gas flow meter calibration agency for calibration. [0003] At present, the natural gas flowmeter calibration system commonly used by calibration institutions is an in-line calibration system, which includes: tracing the flow value of the flowmeter to be tested to the transfer turbine unit, tracing the flow value of the transfer turbine unit to the sonic nozzle unit and The flow values ​​of the sonic nozzle unit are traceable to three in-line calibration blocks of the primary standard unit. [0004] The detection pressure and flow range of the above-mentioned in-line calibration system are greatly affected by the upstream gas source and the natural gas transp...
