依据JJG257-2007《浮子流量计检定规程》,笔者研制了一套气体流量计检定装置。该检定装置主要由空气压缩机、湿式流量计、稳压装置、信号采集装置和计算机组成。该装置由湿式流量计作为主标准器,空气压缩机提供气源,经三级稳压装置进行稳压,气源经被检流量计接入主标准器,在被检流量计入口设有压力和温度传感器,通过流量调节使被检流量计达到要检定的刻度值,湿式流量计气体体积通过数字化处理,在计算机上直接读取检测值。 According to JJG257-2007 “float flow meter verification procedures,” I developed a set of gas flowmeter calibration device. The verification device is mainly composed of an air compressor, a wet flowmeter, a voltage regulator, a signal acquisition device and a computer. The device consists of wet flow meter as the main standard device, air compressor to provide gas source, the voltage regulator by three regulators, the gas source was seized by the main gauge access meter, the seized at the entrance meter pressure And the temperature sensor, through the flow adjustment to be seized flow meter to be calibrated scale value, wet flow meter gas volume through digital processing, the computer directly read the test value.
