摘　　要：燃气流量计体积修正仪中的压力和温度传感器,在长期使用过程中会出现老化以及零点漂移,导致温度和压力值不准,及燃气流量计计量不准。目前燃气流量计的压力和温度传感器长期使用又未进行检定,体积修正仪的误差就会导致偏差越来越大,而且可能会引起贸易纠纷。因此,对燃气流量计中的压力和温度传感器增加定期的检定或比对十分必要。The pressure and temperature sensors in the volume corrector of gas flowmeters will age and zero drift during long-term use,resulting in inaccurate temperature and pressure values and inaccurate measurement of gas flowmeters.At present,the pressure and temperature sensors of the gas flow meter have been used for a long time and have not been verified.The error of the volume corrector will lead to an increasing deviation,and may cause trade disputes.Therefore,it is necessary to add regular verification or comparison to the pressure and temperature sensors in the gas flow meter.
