The invention provides a gauging meter temperature correcting method and device and relates to the technical field of fluid metering. According to the method, voltage waveforms of multiple current signal generation modules are collected to obtain first voltage waveform data; the first voltage waveform data is compared with preset second voltage waveform data so as to obtain the phase difference ofthe first voltage waveform data and the second voltage waveform data; the first voltage waveform data and/or a preset collection time period used for collecting a target voltage waveform data segmentin the first voltage waveform data are/is adjusted according to the phase difference, so that the target voltage waveform data segment is collected in a preset collection period; the voltage difference at a preset collection point is calculated according to the adjusted first voltage waveform data, and then the precision of the gauging meter is improved. In addition, the method and device can correct measurement errors caused by temperature changes in real time, and improve the stability and reliability of the gauging meter.
