description The invention relates to water meter metering, in particular to a self-adaptive metering method of an ultrasonic water meter, which comprises the following steps of: measuring upstream and downstream time and Ttotal and real-time water temperature for multiple times during static flow, and calculating an average value Tref of the upstream and downstream time and Ttotal which are measured for multiple times; the ultrasonic water meter measures upstream and downstream time and Ttotal and the current water temperature in real time in the metering process, and the upstream and downstream time and Ttotal are converted into the upstream and downstream time and Ttotal 'under the set water temperature, and the average value Tref is converted into the average value Tref' under the set water temperature; and the signal receiving threshold value is adjusted based on the comparison result between the upstream and downstream time and Ttotal 'under the set water temperature and the average value Tref' under the set water t
