Abstract: A method and a system for temperature measurement of fluid in a pipe, an electronic device and a storage medium are provided, and relates to the technical field of temperature measurement in a pipe. The method includes: determining fixed parameters of an object to be measured, a flow rate of the fluid, a noise variance and an observation variance; determining a predicted temperature at a current moment according to an optimal internal pipe temperature and a flow rate of the fluid at a previous moment; determining a covariance at the current moment according to the noise variance and an optimal covariance at the previous moment; determining a weight coefficient at the current moment; and determining an optimal internal pipe temperature at the current moment, thereby expanding the application range of temperature measurement in a pipe.
